The company we know today as The Omega Watch Company was founded in 1848 as a comptoir in La Chaux-de-Fonds by Louis Brandt (1825-1879), then 23 years old. Brandt was a merchant who purchased ébauches and other watch parts from specialised makers and had them assembled and finished into watches by other workshops or home workers. Brandt travelled to many countries Europe to take orders for his watches.
In July 1877 Louis Brandt's second son Louis Paul (1854-1903) was named as a partner and the business renamed Louis Brandt & Fils. Louis Brandt died in July 1879. In November 1879 Louis Paul's younger brother, Brand's third son, Charles César (1858-1903) joined him in partnership.
Following a collapse in the Swiss textile trade, the town of Biel/Bienne offered tax breaks to watchmakers who moved there, and the Brandt brothers saw a business expansion opportunity. In December 1879 they signed a lease on the second floor of a factory at 119 Rue de Boujean and moved the company there in January 1880, in the process turning it from a comptoir into a manufacture, where complete watches were made “under one roof”. Their first product was a watch with a cylinder escapement. The first brand names they used were Jura, Patria, Helvetia, Celtic and Gurzelen.
The history of the company begins to divide at this point. In 1880 both “Louis Brandt & Fils” and “Brandt & Frères” were registered in Bienne as watchmakers. In 1882 the Brandt brothers took a lease on a second factory in the Gurzelen quarter of Bienne at 96 Rue Jakob-Stämpfli. They purchased this factory the same year and it remains the home of Omega today. The business separated into two parts; one part making watches with cylinder escapement movements aimed at the lower end of the market and another part making higher quality watches with lever escapement movements.
In 1885 a largely machine made watch with a 19 ligne lever movement was launched under the name “Labrador”. In 1891 the partnership was renamed Louis Brandt & Frère. The name Labrador was registered as a trademark by Louis Brandt & Frère in October 1892.
In 1894 a completely new 19 ligneA ligne, pronounced line, is 1/12 of an old French inch (27.07mm), which itself is 1.0657 of an English inch. So a ligne is 2.256mm. pocket watch movement was introduced which proved extremely successful. Its salient points were the simplicity of its construction, and the interchangeability of its parts which were made by ground breaking new automated manufacturing processes. The company's banker, Henri Rieckel, suggested the name “Omega” for the new watch. The new calibre won a gold medal at the 1896 Swiss National Exhibition in Geneva and made Omega the principal watchmaker in Switzerland, both technically and numerically. The overwhelming success of watches bearing the Omega name led to it being adopted as the sole name used for watches by the company from 1903.
To handle the manufacture of lower quality watches a new company was created, “La Generale” or the General Watch Company. In 1895 a number of trademarks including Helvetia were transferred from Louis Brandt & Frère to the General Watch Company but remained in the ownership of the Brandt brothers. In 1906 the Brandt brothers withdrew from involvement with the General Watch Company, which went on to become Montres Helvetia, Société d'Horlogerie La Générale”.
Omega are well known for making wristwatches and sports timing equipment, but two early waterproof Omega watches are not so well known. One was the Omega Marine, which was the first “dive watch”. The other was the Omega Marine Standard, which has an unusual clip back waterproof case.
In the 1960s, Lanco movements were used in Omega branded watches.

The first British agents for Omega watches appear to have been John Troup & Sons, importers and wholesale jewellers, 36, Hatton Garden, London, who in 1901 advertised that “ We desire to call attention to the Omega Watches, which have come to the front with rapid strides, in Gents', Boys' and Ladies' sizes. Also the New Omega Chronograph (19 Line) in steel, silver, and gold (Crystal Face). A Large Selection of Foreign-made Watches, e.g., The "Helvetia," the "Paradox," the "Fortuna," &c, &c, and the far-famed "Labrador" watch always in Stock.” These will be recognised as all being Brandt trademarks or brad names.
There was some competition for Troup & Sons from Mojon, Manger & Co. who began in November 1902 to advertise that they were “Special Agents for the Omega Watch Factory. Both companies continued to advertise Omega watches until April 1907.
SA: Selling Agency, London
From 1 June 1907 British law required that all imported watches be assayed at a British assay office and stamped with special import hallmarks. The person submitting items for hallmarking had to have a British address and their details and a punch mark registered with the assay office. Swiss watch manufacturers who did not have a permanent office established in Britain at the time used local agents to submit watch cases for hallmarking.
Omega watches imported into Britain from 1 June 1907 carry the sponsor's mark SA in a diamond surround as shown in the image here. The letters SA stand for Selling Agency. This punch mark, shown here, was entered at the London Assay Office on 20 September 1907 by Dimier Brothers of 46 Cannon St. London.
At the time, Dimier Brothers were one of the largest and longest established Swiss watch importers in Britain. After the British law was changed to require all imported gold and silver watches to be assayed and hallmarked in a British assay office, it appears that Dimier Brothers took over the import of Omega watches and formed the subsidiary Selling Agency for this purpose.
O.W.C Omega Watch Company Ltd.
Dimier Brothers acted as sole British agents for Omega until a British subsidiary of the Swiss parent company was formed as the “Omega Watch Company (England), Ltd.” 26-30 Holborn Viaduct, London, E.C.
The Omega Watch Company (England), Ltd. entered its details at the London Assay Office and four punches with the sponsor's mark “O.W.C” in cameo within a rectangular surround with cut top corners on 28 January 1922.
The recorded details were “Omega Watch Company, Gold & Silver Workers, 100 Hatton Gardens EC. The directors were Adrian Brandt, Gustav Brandt, Leon Jobin and Gilbert Dennison. This last person was also Managing Director of the Dennison Watch Case Company. Dennison was an established supplier of watch cases for Omega watches imported into Britain,

Omega's First Wristwatches
In Omega: A Journey Through Time (AJTT) by Marco Richon, a watch on page 104 is described as the first Omega wristwatch dated 1900. The description says that it has a 12 ligne Lépine movement, a .900 silver double-jointed case with fixed central lugs and "a blank shield and floral decoration on the guilloché back", an enamel dial with skeleton Arabic numerals, and blued steel Poire (pear shaped) hands.
This description shows that the watch was originally a fob watch that was later converted into a wristwatch. Here are the points that show this:
- The engraving on the back shows that it was originally made as a small pocket or fob watch. The guilloché engraving on the back with a blank shield in the middle for the owners initials surrounded by floral decoration is usually found on pocket and fob watches but never on purpose made wristwatches.
- The enamel dial has skeleton Arabic numerals to take luminous paint, which dates it to much later than 1900. Luminous dials were not used in 1900, or much at all before 1914, but became an essential feature of military wristwatches during World War One (1914-1918).
- The hands are wrong for a luminous dial, they should be skeletonised to take luminous paint like the numerals. There would be little point in making the numbers glow in the dark if the wearer couldn't tell where the hands were!
- The Lépine movement has the fourth wheel planted in line with the centre line of the winding stem, which would put the small seconds at 9 o'clock. Because of this, the small seconds has been omitted. If this really was a first wristwatch, where the location of the small seconds had not yet been established, then why not bring it out at 9 o'clock? The fact that the small seconds has been suppressed suggests that this happened after the usual location of the small seconds had been standardised at 6 o'clock.
- The fixed central lugs are rather roughly executed, and don't bear any resemblance to the lugs of other early Omega wristwatches. They have clearly been added later in the life of the watch, probably during World War One when many fob watches were converted to wristwatches when the demand for wristwatches by newly commissioned officers exceeded the supply of new wristwatches.
Given all these points, there can be no question that this watch was converted from an open face small pocket or fob watch into a wristwatch. An open face watch was chosen because that is what is required for convenience in a wristwatch, but the layout of the Lépine movement is wrong for a wristwatch so a new dial was made with the small seconds omitted. The fact that this dial has skeleton numerals for luminous paint shows that it was most likely made during or after 1914.
The original fob watch might have been made in 1900, but the dial is in the wrong orientation for an open face fob watch, showing that it was replaced when the watch was converted into a wristwatch. This skeleton numbers for luminous paint show that this was done during World War One as a result of the demand for luminous wristwatches from newly commissioned officers anxious to get to the front. Luminous dials were not used on wristwatches before the war.
The AJTT book also says that the supposedly 1900 wristwatch was followed in 1902 with a man’s wristwatch for jeweller Edwin J. Vokes of Bath. I have yet to see any evidence that this is true - if you have anything that supports this assertion, please let me know. I have a suspicion that this watch was actually the same as the one shown in advert from 1901 by Mappin & Webb for their Campaign wristlet watches, which are known to have contained Omega fob watches.
The watch in the advert is described as: “Mappin & Webb's 'Campaign' Watch. Solid leather wristlet. Small compact watch is absolutely Dust and Damp Proof. Oxydised Steel Case. Reliable timekeeper under the roughest condition. Complete, as illustrated. £2 5s.” The advert says that the watches can be delivered at the front for an extra one shilling. In 1901 the front was the Boer War war in South Africa, although the same watches had been used at the battle of Omdurman, which was fought on 2 September 1898 when a British army commanded by General Sir Herbert Kitchener defeated the army of Abdullah al-Taashi as part of British efforts to re-conquer the Sudan.
I have seen a number of early Omega wristwatches, most if not all with the crown on the left hand side at 9 o'clock. There is no documentation about this but I imagine it was to put the crown in a less vulnerable position when worn on the left wrist - broken stems and missing crowns have always been a regular occurrence with the crown in the “normal” 3 o'clock position.
Although the crown is convenient at 3 o'clock to wind and set the watch when it is being worn on the wrist, this is really very bad for the stem bearings - see Stem Bearings- and Omega perhaps thought that people would not “do the right thing” and take off the watch to wind and set it, so they put the crown on the left side to effectively force them to do so. As far as I recall, all of these early Omega wristwatches carry the Déposé No. 9846 mark in their case backs, showing that they were made after 1903, most likely well after.
This all leaves the story of Omega's earliest wristwatches rather in the dark.
Back to the top of the page.
Early Omega Wristwatch Movement
This is a movement from a wristwatch dated by the case hallmarks to circa 1914/15, so almost certainly a trench watch from World War One. Thanks to Tom at Gungadin Watches for the heads up on this watch, and to Tom and Colin for the photographs.
The screw bezel swing ring case (not shown) has London Assay Office import hallmarks for sterling 925 silver, with the date letter "t" for the years 1914 to 1915 – remember that date letter punches were used over two calendar years. It also has the sponsor's mark SA of the Selling Agency, a branch of Dimier Brothers who were Omega's distributors in the UK at that time.
The Selling Agency sponsor's mark suggested Omega, but definitive proof of the manufacturer is found in the keyless mechanism, the “fingerprint” of a movement. I couldn't find anything like this in the Bestfit and Swartchild books because they are much later, but the keyless mechanism is so unusual with the intermediate wheel is attached to yoke that I managed to find a post Watchmaker Forum which shows a repair to a watch clearly marked Omega on the top plate which has the same keyless mechanism. This led me to a patent granted to Louis Brandt & frère in 1894.
This keyless mechanism is very unusual because, although it is a sliding pinion type mechanism similar to that patented by Adrien Philippe in 1845, the yoke that moves the sliding sleeve also carries the intermediate setting wheel of the hand set mechanism as you can see in the photograph of the keyless mechanism. When the yoke moves the sliding sleeve and intermediate wheel downwards, the intermediate wheel engages with the wheel labelled ‘D’ in the figure, which is the minute wheel of the motion work. Turning the minute wheel sets the hands.
In the usual design of keyless mechanism, the intermediate setting wheel or wheels turn on pivots fixed to the plate and are permanently engaged with the minute wheel. When the stem is pulled into the hand set position, the sliding pinion is moved to engage with the intermediate wheel. In the patented Omega design, the sliding pinion and the intermediate setting wheel are always engaged and the yoke moves them both into gear with the minute wheel. It is an unusual hybrid of sliding sleeve and rocking bar mechanism. The benefit is that intermediate wheel is not permanently engaged with the keyless mechanism so its turning friction cannot affect the normal running of the watch.
The image here of a figure from the Swiss patent granted to Louis Brandt & Frère on 1 August 1894 shows this design of keyless mechanism. The yoke carrying the moveable intermediate wheel is easily seen. Although the mechanism in the figure is reversed left right compared to the one in the photograph, the similarity is clear.
The keyless mechanism definitively identifies the movement as being manufactured by a Brandt company, and movements with the same shapes of the top plates are shown in A Journey Through Time (AJTT) by Marco Richon, Chapter 1, Sister Brands, on page 41 under the brand Celtic, and on page 42 under the brand Regina. (Thanks to Tom C. for pointing this out). I have never seen an imported watch from this period bearing either of these brand names, principally because English retailers refused to stock watches with the names or brands of foreign manufacturers on them, see Names on the Dial.
The serial number in the 4,76x,xxx range is in the right range for an Omega movement made circa 1914/15 and ties in perfectly with the case hallmark date of 1914 to 1915. I doubt that Omega's sister brand movements were given serial numbers from the same sequence as Omega movements. This suggests that the watch would have been branded Omega if English retailers allowed that at the time, hence my identification of this as an Omega watch.
The case was probably sent to England empty and unfinished to be hallmarked, and then returned to the case maker in Switzerland. Unwanted marks from the hallmarking process, scrapes where a sample of material had been drawn and bruises on the outside of the case from where it had been punched inside, were removed and the case was polished. The finished case was then sent to the Omega factory, where it was fitted with its movement.
The finished wristwatch was then sent back to Britain where, at the time, there was a tremendous demand for trench watches from newly commissioned officers getting kitted out before heading off to the front in World War One.
Although the movement does not carry any name at all, the Selling Agency sponsor's mark, Omega sequence serial number, and the coincidence of another watch with the same keyless mechanism that is branded Omega, persuaded me that this watch would have been branded Omega if English retailers allowed that at the time, which they did not. However, Brandt also sold the same movement under the brands Celtic and Regina.

Omega Marine: First Dive Watch
Omega Marine. Photo by Mike Katz, © www.clockfixer.com
In 1932 Omega introduced a waterproof wristwatch based upon Swiss patent CH 146310 granted to Louis Alix of Geneva. This watch was called the Omega Marine and given the Omega reference number 679. The Omega Marine was the first true dive watch; the first watch specifically tested and qualified for diving.
Rolex had a firm grip on waterproof screw down crowns through the patented Oyster crown, so Alix's patent design used for the Omega Marine overcame the problem of making the winding stem water proof without infringing Rolex's patents by the simple expedient of sliding the whole watch inside a second outer casing. The patent was also taken out in France, Britain, the USA and Germany.
In 1936 an Omega Marine was sunk to a depth of 73 metres in Lake Geneva for 30 minutes. In May 1937 the Swiss Laboratory for Horology in Neuchâtel certified the Omega Marine as being able to withstand a pressure of 13.5 atmospheres, equivalent to a depth of water of 135 metres. These were the first tests to establish the depth capabilities of a watch and qualify its suitability for diving.
The Omega Marine was worn whilst diving by Commander Yves Le Prieur, a French Naval Officer and inventor, in 1925, of the aqualung, a self-contained underwater breathing apparatus or SCUBA. The Marine was also worn and endorsed by Dr William Beebe, the American naturalist and explorer who took up underwater exploration in the late 1920s.
Yves Le Prieur (1883 - 1963) was an interesting character. He followed his father into the French navy and served in the far east. He went diving using traditional diving equipment with a weighted belt so that the diver walked on the sea bed and a big, heavy, helmet fed with air down a tube from a pump on the surface. He learnt Japanese, became military attaché at the French Embassy in Tokyo, earned a black belt in judo and was the first person in Japan to take off in an aeroplane, a glider. He returned to Europe and during World War One invented, inter alia, a rocket to bring down balloons and airships, and gun sights that computed the correct angle of fire. He was a creative, restless, inventor all his life.
Commander Yves Le Prieur with his Omega Marine © Captain Jacques-Yves Cousteau and Frédéric Dumas 1957.
In 1925 Le Prieur saw a demonstration of a diver using a breathing apparatus invented by Maurice Fernez. This consisted of a mouthpiece supplied with air through a tube from the surface, a nose clamp and goggles. Le Prieur was impressed by the simplicity of the Fernez equipment and immediately conceived the idea of using Michelin cylinders as the air supply. Michelin cylinders contained three litres of air compressed to 150 kg/cm2 and were supplied by the Michelin tyre company to garages without air compressors for inflation of car tires.
For the first time this invention allowed a diver to submerge without any connection to the surface; Le Prieur had invented the self-contained underwater breathing apparatus, in French "scaphandre", rendered into English as the aqualung or by the acronym SCUBA. The use of unpressurised goggles prevented the diver from going deeper than about 10 metres because the goggles were squeezed onto his face, so in 1933 Le Prieur invented the full face diving mask, a rubber cylinder that covered the eyes, nose and mouth with a glass front to see through. The mask was supplied with air and Le Prieur remarked that the diver could breath through his mouth or nose, or both, at will, and could even talk to other divers by bringing the mask close their ear, the glass acting as a microphone.
In 1934 Le Prieur created a second version of the equipment with a full face mask and automatic pressure reducer. The first diving club was created in France in 1935 by Le Prieur and Jean Painleve, it was called the "club des scaphandres et de la vie sous l'eau", the club for divers and life under water. In 1936 the Le Prieur apparatus was officially adopted as diving gear by the French Navy.
The 1957 book "The Silent World"Ref. 2 by Captain Jacques-Yves Cousteau and Frédéric Dumas shows this picture of Le Prieur diving with his aqualung and wearing an Omega Marine. The face mask is the later version of the equipment so the picture dates from after 1934. The book tells how Cousteau started diving with Fernez goggles in 1936, and in 1939 used Le Prieur equipment for the first time. In 1942 Cousteau made an improvement to Le Prieur's apparatus by adding a demand regulator, invented by his friend Émile Gagnan, which reduced air consumption and thereby extended the length of time that could be spent under water. It made the apparatus better, but Cousteau did not invent the SCUBA.
Dr Beebe is most famous for his 1934 descent in the "Bathysphere" to a depth of 3,028 feet beneath the ocean surface. But Beebe also dived with the older heavy helmet gear and in 1936 he made a dive in the Pacific wearing an Omega Marine. Afterwards he wrote I wore my Omega Marine in the Pacific Ocean at a depth of 14 metres, where the pressure is twice the normal one. My watch sustained this test with success. Its tightness to water and dust and its robustness to corrosion represent a true progress for watchmaking science.
The Omega Marine Design
Louis Alix's design for the waterproof double case, shown in the figure from the patent, had a curved shape in an arc of a circle. Alix doesn't explain in the patent why this was: it may have been to follow the shape of the wrist, or it may have been a purely aesthetic consideration, this was the age of Art Deco after all. I don't think this curved shape was actually ever used by Omega, all the pictures of Omega Marines which I have seen have been of straight (linear) cases. The elegant curved shape envisaged by Alix would have been difficult and expensive to make at the time and challenging even today.
The watch movement, dial, and hands were contained in a rectangular section interior case. This interior case had a shoulder at the end with a groove which contained a gasket. The interior case slid into a rectangular section outer case, the end of which contacted the gasket in the shoulder of the interior case, forming a water tight seal. A large spring clip on the back of the outer case held the two parts of the case together. The clip was necessary to provide the initial seal between the inner case, the gasket, and the outer case, but as the watch was submerged, the air pressure inside the case would remain constant while the water pressure outside the watch increased, pressing the two parts of the case more firmly together, increasing the force on the gasket and making the seal more water tight.
Louis Alix patent CH 146310
The spring clip described by Alix is not how the case clips were actually manufactured. There were two different generations of the Marine case; the first had a massive clasp on the back of the outer case, running right from the top to the bottom. A second generation of the Marine case, from about 1935 onward, had a much shorter clasp hinged close to the bottom edge of the case more like the clip Alix envisaged.
The cases of the Omega Marine were mostly made in steel with the prefix CK, so CK 679, but they were also made in precious metals e.g. OJ 679 (OJ = Or Jeune, yellow gold). The cases were made by the company of Frédéric Baumgartner of Geneva. Although Baumgartner’s name doesn’t appear on any of the cases, his company's Poinçon de Maître is found in gold Omega Marine cases.
In his patent, Louis Alix suggests that the gasket, the item labelled "q" in the figure, should be made of rubber (" caoutchouc"). In contemporary adverts and in the book by Marco Richon OMEGA - A Journey through TimeRef 1 this gasket is said to be leather. Leather is not a very satisfactory gasket material but at the time it was probably better than the rubber that was available.

The patent illustrated a slim crown recessed into a depression on the side of the interior case, but this was not very practical and production models had the crown at the top of the movement, at the 12 o'clock position like a pocket watch. This can be seen in the second of the two pictures here, kindly provided to me by Mike Katz.
The Marine was at first fitted with the manual winding stem wind and set calibre 19.4 T1, created in 1930, then later with the improved 19.4 T2, created in 1935, still a manual winding movement. Omega was rather unusual at the time in referring to their calibres in millimetres rather than ligne sizes, and 19.4 means these movements were 19.4 mm diameter. They were round movements, not shaped to the form of the watchcase. The 19.4 T1 and T2 calibres were available with either 15 or 17 jewels and operated at 18,000 vibrations per hour. Although the Marine would have been an ideal candidate for an automatic winding movement, Omega did not introduce their first automatic movements until 1943, with the bumper automatic 28.10 and 30.10 calibres, and the Marine was never fitted with an automatic movement.
The outer case had a sapphire crystal in the front so that the dial of the watch in the interior case could be seen. Sapphire was chosen because it was much stronger than glass and this was one of the first uses of it for a wristwatch. The watch strap was made of seal skin, which was thought to be more resistant to water than ordinary leather, and had a unique deployment type clasp. If you have one of these original clasps I would like to know.
A longer version of this description of the 1932 Omega Marine and 1939 Omega Marine Standard was published in the NAWCC Watch & Clock Bulletin, February 2012.
The Omega Marine was not an automatic self winding movement so it would have to be manually wound every day. To wind the watch or set the hands obviously meant removing the inner case from the outer. In addition to being a nuisance, this might have worn the sliding surfaces and imposed wear and tear on the sealing gasket, so the watch would need regular attention to retain its full waterproof capability. The Omega Marine would also have been an expensive watch to make, and hence expensive to buy. I would have guessed that this, together with the inconvenience of its design in daily use, would have restricted its popularity to those who really needed a fully waterproof watch or wanted something unusual and were prepared to pay more for it, which is why it is scarce and valuable today.
In A Journey Through Time1, numerous examples of the Marine are illustrated in mixtures of steel and gold, as well as 18 carat gold versions retailed by Tiffany and Cartier in New York. The case design naturally lent itself to the art-deco style in vogue at the time, and Marine's with art-deco dials and strap lugs were produced. Obviously these precious metal cases and art-deco design features weren't necessary in a diver's watch, and are in stark contract to the strictly functional steel cases and easy to read dials of today's diver's watches. It would seem that, just as today, watches with unusual technical features attracted the attention of those who like something different, perhaps because they like impressive gadgets, or to impress their friends, and the Omega Marine sold to many people who wouldn't dream of diving deeper than their local swimming pool.
In 2007 Omega added a reproduction of this watch, the Marine 1932, to its Museum Collection of vintage timepieces. The double case was made in contrasting 18-carat red and white gold, and the series was limited to 135 pieces to commemorate the official certification of water resistance to a depth of 135 metres.
The watch in Mike Katz's pictures is actually a version of the Marine produced by Omega's sister company Tissot. It is branded "Omega Watch Co. Tissot" in the case back and on the movement. Paul Brandt began the process of bringing Omega and Tissot together in 1925, and by 1930 Paul Tissot-Daguette was managing director of Omega as well as a director of Tissot. The two companies became subsidiaries of a multi-national holding organisation, Société Suisse pour l'Industrie Horlogére (SSIH) to produce a complete range of watches, and for joint sales promotions.
When I was writing my article about the Omega Marine that was published in the NAWCC Watch & Clock Bulletin, February 2012, I was told by the Omega museum that there was an example of a Patek Philippe Marine in the Patek Philippe museum with the same case; I have not seen it myself. Patek Philippe would not discuss this watch so it appears to have been the result of some trial work that did not lead to a series of watches.

So who was Louis Alix, the designer of the Omega Marine waterproof case? There seems to be very little known about him. He is recorded in his patents as "Louis Alix of 1 Rue du Commerce, Geneva, Switzerland, a citizen of the French Republic."
The registration announcement for patent CH 146310 shown here appeared in a May 1931 La Fédération Horlogère Suisse. It records Alix's occupation as sertisseur-joaillier, which means jewel setter. Whether this is setting jewels for jewellery or for watch movement bearings is not clear, and I have not been able to establish which this means, or whether there would be a difference between the two terms. I find it easier to believe that a person involved in the manufacture of watches in the 1930s would be interested in designing one of the first waterproof cases, and more difficult to understand how someone setting decorative jewels would be interested in such a technical rather than aesthetic matter, but I really don't know the answer.
I have found four Swiss patents granted to Louis Alix between 1930 and 1941. The first one is the patent for the Omega Marine case, CH 146310, with a prority/registration date of 10th March 1930 and a publication/grant date of 15th April 1931. This patent was also granted in France as 710316, Britain as 365356, USA as 1907700 and Germany as 567213. The French patent reference is always shown with the letters "S.G.D.G" which stand for "Sans Garantie du Gouvernement" or "Without Government Guarantee", the French Government for some reason, while being happy to grant exclusive rights to the inventor, also being careful not to imply any guarantee that the thing will actually work!
Alix's second patent, number CH 160827 was published on 31st March 1933. It was for a spring loaded "bouton de manchette", or cufflink. I find it difficult to think of a watchmaker being interested in designing improved cufflinks, so maybe this does point towards him being more of a jeweller than a watch maker.
His third patent, number CH 204295 "Remontoir de montre étanche" (Crown for a waterproof watch) published 30th April 1939 returns to watchmaking. It is a design of screw down crown for a waterproof watch which appears to be intended to circumvent the Rolex Oyster screw down crown patent. It is absurdly complicated and inelegant, and I am confident just from looking at it that it was never actually used.
The fourth patent, number CH 223807 published 15th October 1942 was titled "Procédé de fabrication de montres et montre obtenue suivant ce procédé" (Method of manufacturing watches and watches produced by this method.) This patent was for making watch cases, or parts of watche cases, from aluminium because of its corrosion resistance and ability to be coloured by anodising. The claims are extremely general in nature and I am surprised that a patent was granted just on the idea that aluminium could be used to make a watch case. However, as aluminium watch cases are very thin on the ground, even I would say almost non-existant, I think it is safe to say that this patent was also not a great success.
So that is all I have discovered about Louis Alix to date. He was a jewel setter, probably in the jewellery rather than the watch trade, and an amateur inventor. The curved shape he proposed for the watch case would have been very difficult and expensive to make, and indicates that he was not engaged in watch case manufacturing, or he would have designed something more practical.
Alix must have hit it lucky with the design of the Omega Marine case at just the time Omega were on the look out for a waterproof case to catch up with, or even get ahead of, Rolex. The design of the Marine case was not even all that original, because cases where the whole watch was contained inside a waterproof outer case had been granted to Jean Finger and Frederick Gruen in the 1920s, and Rolex had even produced a watch called the Rolex Hermetic using the Jean Finger patent. But Alix got his patent because his rectangular sliding case was novel, Omega spotted it and snapped up the rights, and the rest, as they say, is history.
The 1937 Omega Naïad
Omega's first "standard" waterproof wristwatch was the 1937 Naïad. It was named after female spirits of Greek mythology – naïads were nymphs who lived in and presided over fountains, wells, springs and streams.
The Omega Naïad had a snap on waterproof case back. The winding stem entrance into the case was made waterproof by a crown with internal gaskets that sealed against a stem tube protruding from the side of the case.
The watch in the pictures has a calibre 23.4SC movement, the "SC" meaning centre seconds. The calibre 23.4 was introduced in 1936 in small seconds and centre seconds versions, superseding the calibre 23.7. The manually wound 15 or 17 jewel movement runs at 18,000 vibrations per hour (vph) and has a bimetallic temperature compensation balance and Breguet balance spring. The calibre 23.4 was a great success for Omega and was manufactured in several successive versions until 1959, by which time a total of 120,100 movements had been produced.
The movement of the Naïad pictured here has an Omega serial number just below 9 million, which dates it to about 1937.
Omega Naïad case back
The case back carries the words "Waterproof" and "Mod. Déposé" with the Swiss federal cross, which indicates a Swiss Registered Design. The crown is quite slim and unlike the chunkier later model Naïad crowns described below, but it uses a similar method of gaskets sealing against the stem tube to make the stem opening to the case waterproof.
First centre seconds and Omega "Medicus"
The 23.4SC version of the calibre 23.4 was the first Omega wristwatch calibre with centre seconds, the SC designation identifies centre seconds. The 23.4SC movement is 23.4mm diameter and 4.5mm high, slightly thicker than the small seconds version which is 3.75mm high. The extra thickness is due to the centre seconds drive gear, which in this movement is driven indirectly from arbor of the third wheel. For more about indirect drive centre seconds see centre seconds.
Because its centre seconds hand was useful when taking a pulse rate, the watch was marketed to medical personnel as the Omega "Medicus".
Later Naïad Crowns
Early Omega Seamaster 300s used Naïad waterproof crowns. Rather than the screw down design of the Rolex Oyster, this Naïad crown used a "sealing pack" in the crown which sealed against the stem tube. The sealing pack was designed so that at atmospheric pressure it was compressed lightly against the stem tube, but as the pressure increased the sealing pack was compressed tighter onto the stem tube. The deeper the watch was submerged, the greater the water pressure and the tighter the crown sealed. The picture here from an Omega advert is the best that I have found so far, and the details are not very good, if you have a better one, please let me know.
Omega advert detail of Naïad crown
The design of the Naïad crown was sound in theory, and worked well in practice until the sealing pack aged and lost its elasticity. When this happened the seal against the stem tube was no longer enough to keep out water if the watch was submerged a small distance. Because of this a story grew up that the Naïad crown actually required the presence of significant water pressure to make it seal, and that at shallow depths, when pressure was not as great, water could seep past the seals.
A moments thought will reveal that this cannot possibly be true; you can't get to great depths without passing through shallow depths, and if the crown always leaked at shallow depths then the watch would take in enough water to ruin it (which is a very small amount) before the crown sealed. No watch like this could be sold, at least not in the quantities and over the many years that Omega sold watches with Naïad crowns, so this story is wrong. It resulted from customers not having their watches serviced and the seals replaced at the recommended intervals. It should go without saying that old Naïad crowns must not be assumed to be watertight.
The eventual replacement of Naïad crown on watches like the Omega Seamaster with a screw down crown was mainly to appeal to public perception; the Rolex Sea Dweller had a screw down crown, which Rolex made a lot of in advertising, so the Seamaster also acquired a screw down crown in order to compete for sales. The screw down crown has the benefit that it does not depend on any elastomers that could perish with age for sealing. Its drawbacks are that it needs to be unscrewed to wind the watch, and that until recently screw down crowns did not seal when unscrewed, as many unfortunate owners discovered – but they couldn't blame that on anyone but themselves.
This problem with screw down crowns was overcome by the introduction of automatic winding, and elastomer seals that maintain a seal when the crown is unscrewed - but these can still perish and let in water if they are not replaced at the recommended intervals, just like the Naïad crown.

The 1939 and 1941 Omega Marine Standards
Photo © Jeff Chiang www.oldwatch.club.tw
Following on from the 1932 Omega Marine, in 1939 Omega introduced another rectangular waterproof watch called the Marine Standard. The designation "standard" showed that it was intended for serial production as part of Omega's standard range, unlike the 1932 Marine which was a specialised product.
The Marine Standard had a simpler rectangular case than the Marine, which was cheaper to make and also had the crown on the outside of the case so that it was easy to wind every day and set the hands to the correct time. The Omega reference number for this watch was 3635 with prefix CK for steel case.
The 1939 Omega Marine Standard contained an Omega calibre T17 movement. This was a manually wound that came in either 15 or 17 jewel versions, the 15 jewel version was used in steel cases, the 17 jewel version in gold. The T17 had an unusually long duration of up to 60 hours running on a single winding. The T17 movement measures 17 x 24.5 x 3.85mm.
Versions of the Omega Marine Standard with a sapphire crystal were called the "Deluxe Marine", reference 3637. A smaller ladies' version was produced in 1940, reference 3673 fitted with a calibre R 13.5 movement, which also came in 15 and 17 jewel versions. The R13.5 movement measures 13.5 x 17.5 x 3.25mm.
A later version was the 1941 Marine Standard with reference number 3683, prefix CK for steel case or OJ for yellow gold 18 carat case. They were fitted with calibre R17.8, 15 jewel, manually wound movement, an early "fast beat" operating at 21,600 vph. The calibre R17.8 was a very successful movement for Omega, being made from 1940 until 1961.
The cases of the 1939 and 1941 Omega Marine Standards were designed and patented by Frédéric Baumgartner, a Geneva based case maker.
The 1939 Marine Standard
Patent CH 215449 crystal sealing gasket detail
Waterproofing in the 1939 model was achieved by rubber gaskets for the crystal and in the case back. The case back was held in place by two very distinctive spring clips.
Baumgartner was granted two patents on the design of this case. The first, CH 215449 was registered on 28 August 1940 and concerned a method of sealing the joint between the crystal and the case. The second patent, CH 216460 was also registered on 28 August 1940, concerned a design of clip back case.
The figure from the first patent CH 215449 shows how the joint between the crystal and the case was sealed by a rubber gasket. The rectangular plastic crystal 3 was moulded with an annular groove 4 having a lower shoulder 5 and an upper shoulder 6. The sealing ring or gasket 7 rests on the shoulder 5. The bezel presents an annular projection 8 which enters the groove 4 of the crystal, and the upper edge of the groove 4 in the crystal engages over the shoulder 6 of the bezel, while the lower shoulder 5 of the crystal presses the sealing ring against the bezel.
The crystal and gasket are fitted from inside the case before the movement goes in. To mount the crystal and sealing ring in the bezel they are simply pushed upwards until the shoulder 6 of the crystal is forced past projection 8 of the bezel, which then clips into the groove 4 in the crystal and holds the crystal and gasket in place.

Patent CH 216460 cross sectional detail
The second patent, CH 216460, concerns the design of the case. In CH 216460 the crystal is shown mounted in the same way as in patent CH 215449, simply clipped into place from inside the case.
Although increasing water pressure would press the case back harder onto the gasket, increasing the seal, it would have the opposite effect of pressing the crystal into the case and reducing the pressure on its gasket, thus weakening the seal. The seal between the crystal and the inner case was hence the weakest part of the design, and limited its water resistance to 10 metres.
The design actually used for the first iteration of the Omega Marine Standard was a mixture of the designs shown in the first two patents. The inner case was separate from the outer case, as shown in patent CH 220263 and as can be seen in the photographs kindly provided to me by Jeff Chiang. The crystal was fitted to this inner case from inside, clipping into the bezel and securing the gasket as shown in patents CH 215449 and CH 216460. To assemble the watch, first the crystal and gasket were clipped into the inner case. Then the movement and dial were inserted into the inner case and the crown and winding stem inserted and fixed in place. The inner case was then placed inside the outer case, and the case back with gasket offered up. Finally the two clips were sprung into place in grooves in the case back, holding the case back and gasket firmly against the inner case, and holding the inner case inside the outer case.
Both patents CH 216460 and CH 220263 show an inner case which is open at the back, and is enclosed in an outer case with two hinged clips. The case back is separate and has a groove around its outer edge which carries a gasket. When the case is assembled, the two clips on the outer case hold the case back against the inner case, and a seal is made between the inner case and the gasket in the case back. The difference between the two patents is that the first, CH 216460, shows the inner case welded to the outer case whereas the second, CH 220263, shows the inner case as a sliding fit into the outer case.
The 1941 Marine Standard
Patent CH 220263 cross section
Omega Marine Standards made to the design of patent CH 220263 were called the Marine Standard 1941 and given the reference number 3683, with prefix CK for steel case or OJ for yellow gold 18 carat case. They were fitted with calibre R17.8, 15 jewel, manually wound movements. The R17.8 was a very successful movement for Omega, being made until 1961. It was an early "fast beat" movement operating at 21,600 vph.
The patent CH 220263 shows the crystal inserted into the bezel from the front. This gave better sealing at pressure, because now the crystal was forced harder down onto its seat as the pressure rose rather than being forced away from it.
The method of sealing the winding stem where it enters the case is not described in Baumgartner's patents. The crown is on the outside of the case and therefore the opening in the side of the case which the winding stem passes through must be sealed. This must have been by a gland sealing against a tube projecting from the side othe case and housing the stem like the crown of the 1937 Omega Naïad.
Patent CH 220263 showing distinctive clips holding back
The clips holding the back in place are very distinctive, enabling recognition of this case design from just a view of the back of the case. You can see the clips in one of the pictures, and in the figure from the patent. Although the outer case and inner case look as though they were forged, they must have been very precisely made or machined, because the clips work to hold the whole assembly together just on the small amount of " spring" available from the case back gasket.
I have never seen an Omega Marine Standard with the Baumgartner patents marked on it. There is usually a list of the patents for the Louis Alix patented design of the 1932 Omega Marine described above in the case back. This may have been because Baumgartner was a bit slow in getting his patents registered in 1940 and 1941, some time after the Marine Standard was actually introduced in 1939, and the Louis Alix patent numbers were stamped into the cases to provide some vague warning that the design was patented before that was actually the case. I can't think of any other reason, because the two designs are totally different.
Baumgartner also supplied cases Tissot for a Tissot version of the Omega Marine Standard, at least some of which were called " Aquasport". The cases of these Tissot versions of the Marine Standard which I have examined are obviously an evolutionary development of the Omega Marine Standard design.
In the Tissot version of the Marine Standard that I have seen, there is no separate loose inner case carrying the crystal. There is instead what looks like a friction fit inner case that traps the crystal and a gasket between it and the outer case. On the Tissot which I have, I not been able to remove the inner case from the outer case, and think these inner cases may have been press fitted together at the factory, in which case a damaged crystal would probably need a trip back to the factory to be replaced. One of the benefits of this modification is that the clamping force of the clips on the back compresses the crystal gasket as well as the case back gasket, which is an improvement over the design of the Omega Marine Standard.
In addition to Omega and Tissot, Baumgartner supplied these clip back cases to Jaeger LeCoultre, Movado, Longines, and possibly others. Watches in these cases are also seen marked Bravingtons, a renowned jewellers in Kings Cross, London, who retailed watches under their own name.

An interesting question is why the company Frédéric Baumgartner with apparently no previous history of making waterproof cases should suddenly start making them.
1939 Baumgartner Advertisement
1939 Taubert Advertisement
The quarter page advert by Baumgartner is from the 1939 edition of La Classification Horlogère des Calibres de Montres et des Fournitures d'Horlogerie Suisse by AF Jobin. The advert says that Frédéric Baumgartner are a Manufacturer of Jewellery-Watches (Manufacture de Bijoux-Montres) and that they make watch cases in gold, platinum and staybrite stainless steel, and of very fine quality (Qualite tres soignee). There is no mention of waterproof watch cases in the Baumgartner advert, even though it was created only shortly before the Omega Marine Standard was launched.
Contrast the Baumgartner advert with the full page advert from Taubert & Fils, also a Geneva watch case maker, but this time one specialising in waterproof watch cases. The watch in the Taubert advert is not exactly strapped around the submarine, more draped across it. But the meaning is clear, the watch is being dashed by waves but is not harmed by them, and just in case it is any doubt, the headline drives the point home "The waterproof watch par excellence".
These two adverts are clearly from companies specialising in different areas: Baumgartner in jewellery watches of very neat quality, Taubert in waterproof watches.
Members of the Swiss union of watch case makers mark cases made of precious metal with a stamp, or Poinçin de Maître (Punch of the Master) consisting of a symbol called a collective responsibility mark, and a unique number which is assigned to each maker.
The mark shown in the image here of a small Geneva key with the number 2 on the lever is in a Patek Philippe case back with Swiss hallmarks for 18 carat gold. Thanks to TimeZone member candle7 for permission to use the image, and for the information that the watch is a 1962 Patek Philippe ref. 3434, which is not a waterproof watch.
Patek Philippe case back
The collective responsibility mark of the Geneva key and number 2 was registered to F. Baumgartner SA of Geneva, and the Classification Horlogere Suisse confirms that F. Baumgartner SA of Geneva, case maker, was Frédéric Baumgartner.
The cases of the 1932 Omega Marine were mostly made in steel with the prefix CK, so CK 679, but they were also made in precious metals e.g. OJ 679 (OJ = Or Jaune, yellow gold). Although no name appears on any of the cases, Frédéric Baumgartner's Poinçon de Maître is found in gold Omega Marine cases, which suggests that all the cases for the 1932 Omega Marine were made by Baumgartner– it seems unlikely that different companies would be used for steel and gold cases because that would double the setup and tooling costs.
I have found 8 Swiss patents granted to Frédéric Baumgartner of Geneva starting with a 1928 patent for the design of a protective case for a pocket watch similar to the Movado Ermeto. This case is to protect a watch against knocks by other items being carried in the same pocket or purse, and there is no provision for making it waterproof. A UK version of this patent gives Baumgartner's address as 13 Coulouvrenière, Geneva. Apart from the three patents for the clip back case used for the Omega Marine Standard, registered in 1940 - 1941, none of the other patents concern waterproof watch cases.
|CH138646||1929-09-23||Pièce d'horlogerie||Flip open case for a small clock.|
|CH135793||1928-12-01||Montre||Protective case for pocket watch.|
|CH148031||1929-09-23||Pièce d'horlogerie||Flip open case for a small clock.|
|CH187166||1935-11-11||Montre-bracelet||Method of attaching strap to watch case.|
|CH205590||1938-05-09||Montre-bracelet||Method of attaching strap to watch case.|
|CH215449||1940-08-28||Boîte de montre étanche||First waterproof watch patent.|
|CH216460||1940-08-28||Boîte de montre-bracelet||Second waterproof watch patent.|
|CH220263||1941-06-30||Boîte de montre étanche||Third waterproof watch patent.|
From the evidence here, it appears that the three patents granted for the design of the rectangular clip back case used for the Omega Marine Standard were Frédéric Baumgartner's only patents concerning waterproof watch cases. It appears that after the experience of making the waterproof cases for the 1932 Omega Marine to Louis Alix's design and patent, Baumgartner decided to design and patent their own waterproof case. Whether they made any other designs of waterproof case after this one is not known.

Omega WWW wristwatches ref. CK 2444
Omega W.W.W. wristwatch ref. CK 2444 on one of my leather G10 straps
Beginning in 1945 Omega supplied wristwatches to the British military under the War Office Specification No. R.S./Prov/4373A "Watches, Wristlet, Waterproof" (W.W.W.), which replaced the Army Trade Pattern (ATP) specification wristwatch. The picture shows one of these watches on one of my leather G10 straps, which I think looks more "period" than the Perlon or nylon straps these watches are usually fitted with.
The second picture shows a close up of the case, with its unusually long horns and fixed bars. The long horns that create a big gap between the case and the bars of these early W.W.W. watches were designed this way for webbing and leather straps. Later service watches have a smaller gap between bars and the case which makes them less suitable for the thicker webbing or leather straps and were clearly designed for either thinner nylon straps or clip-on Bonklip bracelets.
There is some evidence that leather straps were used at the time the W.W.W. specification was introduced. Kenneth Gordon (author of the "Zulu time" articles in the BHI journal) told me he believes that the Mk.11 pilot's watches were originally issued with leather straps. Def. Stan. 66-4 part 4 is a standard dated 1980 and the final table of "items no longer to be provisioned" lists an Air Force strap 6B/169 in leather.
Omega W.W.W. wristwatch ref. CK 2444
The dial and case back carry the pheon (broad arrow) denoting British military property, and the case back also carries the W.W.W. initials, a reference to the order code, usually beginning with a Y, and the case serial number. The dial is matt black with recessed small seconds at 6 o'clock, minute track with luminous dots, white Arabic numerals and sword hands with luminous radium based paint. The steel case is water resistant and satin brushed to reduce reflections. The lugs have fixed (soldered) bars for security.
The movement is an Omega calibre 30 T2 with special adjustment in four positions to within ten seconds per day as for a chronometer. Omega say that a total of 25,000 watches were supplied to this specification.
The original version of the W.W.W. specification did not require shock protection for the balance and none of the wristwatches supplied under it had shock protection. A provision requiring shock protection appears to have been introduced as part of the amendment to the W.W.W. specification in 1947.
In the book "OMEGA – A Journey through Time" Marco Richon shows one of these Omega W.W.W. watches on a two piece open ended strap. It is clearly not a one piece strap because a gap can be seen between the case and the bars, so it must be a two piece strap, and it must be an open ended strap because of the fixed bars. This is totally inappropriate; the fixed bars were specified for strength and security, and they were paired with a one piece pull through British military standard G10 strap. In that way, even if one of the fixed bars, which were solid and already much stronger than a spring bar, was to give way, the watch remained securely fastened to the wearer's wrist. If you want a strap like this, click on this link: leather G10 straps.

Charles Tissot & Son, Le Locle, Geneve, La Chaux de Fonds, was founded in 1853 as Charles F. Tissotby by Charles Félicien Tissot-Daguette with his son Charles Emile Tissot-Daguette. They developed a strong market in Russia but this was lost due to the Russian revolution in 1917. Tissot claim to have produced their first wristwatch in 1900 but I am not convinced about this. There were close family connections between Tissot and Omega.
Omega and Tissot
After the New York stock market crash of 1929 and the subsequent worldwide financial crisis, the market for watches collapsed. In 1930 Paul Tissot-Daguette was Managing Director of Omega. Under his leadership Tissot and Omega formed a joint marketing organisation, Société Suisse pour l'Industrie Horlogére (SSIH) so that between them they could produce a complete range of watches whilst maintaining separate companies.
The Omega and Tissot factories produced movements for both brands, the Omega factory specialising in more complex movements, such as some automatic self winding movements, and Tissot the simpler movements. Where essentially the same movements were produced in both factories, most parts are interchangeable. But there are usually some differences between Omega and Tissot variants to prevent swapping movements between brands by watchmakers. Usually the dimensions were sightly different, but as Tissot tended more to the medium price range, some Tissot details were cheaper, such as Omega using a balance spring with a Breguet overcoil, whereas the Tissot counterpart would have a flat balance spring. A flat balance spring could be used in the condition it came from the spring manufacturer, just cut the to right length. But a Breguet overcoil had to be formed by hand, which was a skilled operation and increased the component cost of the spring considerably.
It is sometimes said that the Tissot Antimagnétique introduced in 1930 was the first antimagnetic wristwatch, not susceptible to magnetic fields. This is not correct.
Balance springs and compensation balances and were traditionally made of steel, a material that can become magnetised when exposed to a magnetic field. This plays havoc with the timekeeping, and can even cause the watch to stop. There are two ways in which a watch can be made not susceptible to magnetic fields. The first is to make the balance and spring from non-magnetic materials. This is sufficient for most purposes. However, if it is possible that the watch will be exposed to very strong magnetic fields, it is necessary to enclose the movement in an iron capsule that diverts external magnetic fields away from the movement.
The problem of magnetism affecting watch balance springs had become known as soon as electricity started to be used outside the laboratory in the nineteenth century, and watches that were not affected by magnetic fields were made then. Palladium balance springs were discussed for this purpose in 1887, and nineteenth century American railroad watches were required to be protected against magnetism.
The Tavannes Submarine wristwatch made in 1915 was specifically required to be antimagnetic, because a submarine uses batteries and electrical motors when under water and therefore contains electrical fields that can magnetise an ordinary wristwatch. In 1901 Paul Perret was advertising balance springs for non-magnetic watches and many of these were used in wristwatches.
So Tissot were far from the first to make an anti-magnetic wristwatch. However, they may have been the first company to make a big play in advertising about an antimagnetic a wristwatch.

General Watch Company: Helvetia
In 1880 the Brandt brothers moved their comptoir business “Brandt Fils” to Biel/Bienne and transformed it into a manufacture, which subsequently became the Omega Watch Company. One of their trademarks at the time was Helvetia.
In 1895 the Brandt brothers founded the General Watch Company as “Société d'Horlogerie La Générale” with factories in Biel/Bienne and Reconvilier. The General Watch Company was created to manufacture ébauches with cylinder escapements aimed at the lower end of the market. In 1895 a number of trademarks including Helvetia were transferred from Louis Brandt & Fils to La Générale.
The company remained in the ownership of the Brandt brothers until 1906 when they withdrew from involvement with the General Watch Company which went its own way, soon diversifying into better quality watches with lever escapements such as the one shown here. This movement is from a Borgel wristwatch with London Assay Office import hallmarks for 1918 to 1919. There are some more General Watch Co. movements from around the same period, including one used in Rolex Watch Co. Marconi brand watches, at GW Co. Movements.
Brand names used on watches produced by the General Watch Company included Helvetia, Orta and Paradox, and many other less well known including Elsinore. The advertisement shown here is from from the 1920 edition of the Indicateur Davoine.
In 1949 the company changed its name to “Montres Helvetia, Société d'Horlogerie La Générale”.
In 1931, during the financial crisis of the Great Depression, the Swiss Government and banks forced the creation of the Société Générale de l'Horlogerie Suisse SA, better known as Allgemeine Schweizerische Uhrenindustrie AG (ASUAG), as an association to prop up many watch industry companies that were in financial trouble. Helvetia became part of this organisation in 1971.
There is a good history of the General Watch Co and Helvetia at Helvetia History.

S. A. D. A.
In April 1914, a joint-stock company for the manufacture and trade in watches and all related components and similar items was created under the name Societe Anonyme Department Achats or S. A. D. A. (or Anonymous Sales Department!)
Adrien Brandt, resident in Biel, and Gustave Brandt, resident in Paris, both from Lole [sic: Locle?], were elected as delegates of the Board of Directors and individually bore a legally binding signature for the company.
A large number of trademarks were subsequently transferred to S. A. D. A. by Louis Brandt & frère (Omega Watch Co.), including Patria and others less well known such as Avoca, Critic, Ethic, Meric, Saint Bernard (with an image of the dog), Valdez and Vivid.
On 19 May 1916, S. A. D. A. registered the name “Vertex” as a trademark. On 7 July 1916, Claude Lyons of London also registered the name “Vertex” as a trademark. This is a mystery; there is no known connection between the two companies or any record of the mark being transferred from S. A. D. A. to Lyons.

Lanco is one of the names used by the Langendorf Watch Company of Langendorf, Switzerland. The company was founded in 1873 by Colonel Johann Viktor Kottmann (1822–1881) and remained in the ownership of his family until 1965.
A factory to make watch movement parts to sell to other companies was established with 70 to 80 workers. The company nearly failed in 1880, allegedly due to alcoholism and absenteeism in the workforce. However it was turned around by Johann's son Karl Kottmann (1844–1890) and by the end of the 1880s it was considered by some to be the largest producer of watches in the world, although some of the American factories would have called that into serious question.
In 1964 due to challenging business conditions the company joined a conglomerate of watch manufacturers called Schweizerischen Gesellschaft für Uhrenindustrie A.G. (SGU). However, this did not solve all the difficulties and, in 1965, the company was sold to SSIH.
After the takeover of the Langendorf Watch Company by SSIH, watches with the Lanco brand name were made with the same movements as found in Omega and Tissot branded watches.
Production at Langendorf ended in 1973 and the factory was replaced by a shopping centre, but the Lanco name lived on, it is now owned by The Swatch Group.

Omega purchased many movements from the ébauche manufacturing company Mark Favre. For instance, the first Omega's first men's automatic rotor calibres 470 and 471 from 1955 were made by Favre.
The company Mark Favre & Co SA was founded in the Madretsch district of Bienne in 1905. It manufactured high quality lever escapement movements in sizes from 7¾ to 13 ligne. During World War One the company supplied movements to Gruen.
In 1930 the Société Suisse pour l'Industrie Horlogére (SSIH) was formed, incorporating Omega, Tissot, Lemania, Rayville, Lanco, Cortebert, Marc Favre and Hamilton.
Omega appear to have first sourced movements from Mark Favre in 1955 with the rotor automatic calibre 470. For the next decade or so, Favre supplied Omega with millions or movements. Amongst these was the 480 series of 12.5 × 15.2 millimetre tonneau movements, 480, 481, 482, 483, 484 and 485, which were regarded as very reliable ladies calibers, widely used in gold jewellery watches, especially the Omega Saphette. A total of 3,330,000 of these were supplied by 1969.
Favre also supplied a series of 28mm movements, the calibres 490, 491 and 500 to 505 for Omega Seamaster and Constellation watches, including the calibre 503, which was the first Omega calibre with a date aperture at three o'clock and the first with rapid date setting at midnight.
From 1960 Favre supplied Omega with a series of 27.90mm, 13 ligne, movements, calibres 550 to 565, which were used Seamaster and Constellation watches.
