H. Williamson
Copyright © David Boettcher 2005 - 2023 all rights reserved.H. Williamson was established in 1865 in Coventry by Henry Williamson as a dealer in, and later manufacturer of, jet jewellery. Jet is a hard black fossilized wood that can be carved and highly polished. Queen Victoria wore jet from Whitby as part of her mourning dress after the death of Prince Albert in 1861 and it became extremely fashionable. When jet went out of fashion in the 1880s the company diversified into other areas.
The firm grew rapidly to become a huge wholesale business. The head office and show room was at 81 Farringdon Road, London. There were factories in Birmingham and Coventry.
In 1892 the firm was incorporated as a limited liability company as H. Williamson Ltd.
Henry Williamson went into semi-retirement due to poor health and failing eyesight in 1906, and died in 1914.
Following the financial crash of 1929 and the subsequent world-wide depression, H. Williamson Ltd. became insolvent in August 1931 and was liquidated.

Williamson and P & A Guye
The advertisement reproduced here from The Watchmaker, Jeweller and Silversmith of June 1893 says that H. Williamson, Ltd., 81 Farringdon Road, London are the sole agent for the United Kingdom for P & A Guye's movements in London made cases.
Culme shows that two punch marks “HW” in cameo within an oval surround were entered at the London Assay Office in 1888 by Henry Williamson. A sterling silver watch case with one of these HW sponsor's marks and the date letter “R” for 1892 to 1893 containing a Guye movement has been seen. This suggests that H. Williamson were having watch cases made for them in London, hallmarked under their own registered sponsor's mark (which was a common practice) and fitted with movements such as those from P & A Guye.
The address of P & A Guye at 77 Farringdon Road is interesting, because Grace's Guide lists H. Williamson's address in 1922 as 77-81 Farringdon Road. The same guide lists Williamson factories in Birmingham and Coventry, and branches in Manchester, Auckland, Calcutta, Johannesburg and Sydney.

Williamson and Errington
In November 1895, it was announced that H. Williamson had taken over the watch manufacturing concern of Mr. Charles H. Errington, Holyhead Road, Coventry. Although little known outside Coventry, Errington's establishment was said to be of considerable extent. Before the acquisition of the Errington watch company, Williamson had made only clocks at a factory in Salisbury and acted as agents for other companies, notably the watchmaker P & A Guye but also quite likely Errington, which would be how they became interested in the factory. For twenty years Errington had devoted himself to the production of low cost watches, being granted a number of patents for improvements in watch movements.
In announcing the acquisition of the Errington Watch Factory, a name that was continued, H Williamson said that it possessed “the most perfect system of Machinery in this Country for the Manufacture of High Class Watches, Keyless and Key-Winding, ¾ and full-plate.
Cutmore says that because Errington had finished rough movements made by James Berry of Prescot, when H. Williamson acquired the factory there was no machinery for the manufacture of the watch plates or other basic parts. It is believed that Williamson acquired machinery for making plates and other parts in 1896 from the failed English Watch Company. However, this is rather contradicted by the statement made by Williamson's on taking over the Errington factory.
In 1898 H. Williamson's main premises at 81 Farringdon Road London was said to be extensive and imposing, with commodious offices at the front and a very large shipping department at the back, with warehouses, workrooms, a large packing department and numerous departments handling gem stones, jewellery, items of silver plate and electro plate, and a large clock, optical and watch department. “There were many excellent lines of Swiss watches . . . the majority of which are manufactured exclusively for the company.”
The building at 11 Spencer Street, Birmingham, with a factory and offices, had been built for the Reading family of jewellers circa 1871. It was acquired in 1899 by H. Williamson Ltd., who used the offices and made electroplated silver wares in the factory.
In May 1909, a fire completely destroyed the Salisbury clock factory, which covered nearly an acre of ground, in little more than one hour, and the whole of the stock, plant, and machinery, including tools, models, plans, drawings, calculation lists, and everything connected with the factory, were completely destroyed. A new factory for making clocks was set up in Coventry under the direction of Charles Errington who pulled off an extraordinary achievement in getting together a complete plant, machinery, tools, etc. in a few months, designing a completely new clock movement, the first “Astral”, which met with exceptional praise from experts and others who examined it. Charles Errington continued working for H. Williamson as manager of the Coventry watch factory until his retirement in June 1910.

Williamson and Büren
In 1898 Williamson purchased the Swiss company of Fritz Suter & Co, watch manufacturers in the town of Büren an der Aare in the canton of Bern, Switzerland, and in 1899 the factory of Albert Montandon in la Chaux-de-Fonds. The factory in Büren was acquired specifically to supply parts such as the train wheels and pinions, mainspring barrels and arbors, and escapement parts, to the watch factory in Coventry. These parts were incorporated into watches of English appearance, with plates that were made in Coventry. These watches were advertised as “English Lever” and “Keyless English Lever” watches.
In 1899 the Lancashire Watch Company, who had previously supplied watches to Williamson before they started making their own movements with imported Swiss parts, took out a prosecution under the Merchandise Marks Act (1887). Williamson were found guilty of applying a false trade description to watches with Swiss train wheels and other Swiss made parts. As a result of this, Williamson purchased Swiss machinery so that they could make the parts in Coventry, which meant that the Swiss factories were no longer needed for this purpose.
Rather than close or sell off the Swiss factories, Williamson began making complete watches there and importing them under the brand name Büren.

W.H.S sponsor's mark for imported watch cases
Imports of watches from the Büren factory no doubt increased as the demand for expensive English made watches decreased. Swiss watches in gold and silver cases with Swiss hallmarks were imported without any problems until 1907. Then in 1907 the British authorities woke up to the fact that this was against the law, and required that all imported gold and silver watches be assayed and hallmarked in a British assay office. This caused a scramble amongst watch importers such as Williamson to service the requirements of hallmarking, which meant that they had to have a sponsor's mark registered with one or more assay offices.
As major manufactures and wholesalers of gold and silver Williamson already had sponsor's marks registered with the London Assay Office. Henry Williamson had first registered his mark H.W as gold worker on 4 February 1887, and various H.W.Ltd marks were registered after the company had become limited, but a different sponsor's mark was registered specifically for use on imported watch case, the mark W.H.S within a shield with angled ends shown here.
The first sponsor's mark punches with this mark were entered at the London Assay Office on 22 June 1907 by William Henry Sparrow, described as an importer of gold and silver watches, 11 Spencer Street, Birmingham. Two additional punches with the same mark were registered on 4 July 1907, and two further punches with the same mark on 3 May 1909.
These simple registration details conceal an interesting story. Philip Priestley records that Sparrow was “possibly” Manager of the Errington Watch Company Case Department, so it would make sense that when Errington was acquired by Williamson in 1895, Sparrow continued in charge of the manufacture of watch cases. When the law changed to require imported watch cases be hallmarked, he was the obvious person to enter a sponsor's mark for that purpose.

Merchandise Marks Act Prosecution
In November 1899 H. Williamson Ltd. were accused of breaching the Merchandise Marks Act of 1887 by falsely applying to certain watches the description “English lever,” and of exposing for sale certain watches falsely described as made in England. It was not disputed that the watches in question did contain several parts of foreign manufacture, or that they were sold as English lever watches with the English hallmark upon their cases. Williamsons admitted that in some watches the barrel arbor, the cap studs, the centre wheel and pinion, the third wheel and pinion, the fourth wheel and pinion, the pallets, the pallet staff, balance cock, main spring, balance spring, balance and barrel were made in Switzerland.
Williamson contended that the train and other foreign parts used in these watches were on the same footing as the balance and spring mainspring, which were nearly always of foreign origin in all English watches. They also contended that the foreign parts need not be considered in the description because they were imported in the rough and had to be shaped, polished and fitted in Coventry. These arguments were not accepted by Mr. Chapman, the magistrate who heard the evidence in the case, and in March 1900 Williamson were found guilty, fined £20 with £10 costs and the watches confiscated.
An article in the Horological Journal in 1948 said that a result of the trial was that a new Merchandise Marks Act precluded any British watch or clock factory from using more than sixpennyworth of material, which the article said “just covered the cost of a hairspring”. In fact, it covered more than that as can be seen from the Williamson Astral pocket watch shown in the next section, which has a Swiss made balance, balance spring and mainspring, and the jewels are also almost certainly Swiss made, which is why it has only 7 jewels. At the time, jewels were mass produced in Switzerland by automatic machinery, but in England they were shaped and formed by hand, which made them much more expensive than the Swiss. The Williamson movement would be better, longer lasting, with 15 jewels, but the number was probably kept to seven to stay under the sixpennyworth limit on Swiss materials.
The judgement in the case probably didn't come as a surprise to Williamsons because even during the case they had been importing Swiss machinery to be used at the Coventry factory to make parts which were previously imported from Switzerland. After losing the court case, Williamson extended the Coventry factory so that they could make all of the parts there instead of importing them, although they continued to use Swiss balances, balance springs, mainsprings and jewels. The Swiss Büren factory remained owned by Williamson, but now made complete watches marked “Swiss Made” for sale in the UK and elsewhere.

Williamson Astral

In 1910, H. Williamson introduced a new watch brand, the “Astral”.
The pocket watch shown here is a Williamson Astral in a gold plated Dennison Star grade case. The movement with its exposed winding wheels looks Swiss, but it was made actually in Coventry by H. Williamson Ltd. in around 1910. The reason for the Swiss appearance is that Williamson had been assembling movements in its Coventry factory using parts made at its Swiss factory in Buren, but this was found to be illegal after Williamson were prosecuted under the British 1887 Merchandise Marks Act.
Warranted English
After the Court case over the Merchandise Marks Act, Williamson started to mark the movements made in the Errington Watch Factory with “Warranted English”, either on the top plate or on the ratchet wheel as shown here.
As a result of the loss of the court case, they had imported Swiss machinery so that they could make almost all of the parts in Coventry, but the movements retained a characteristic Swiss appearance, with exposed winding wheels and a straight line lever escapement. After the Court case and the increase in the use of parts made in Coventry, Williamson issued a guarantee with each watch that said it was “guaranteed to be a genuine English Lever, the whole of its parts being of English Manufacture with the exception of a trifling amount of Foreign material which does not exceed the value of 6d.”
Although the movements and their component parts were then mainly made in Coventry, there were still some Swiss parts. At the time, English watchmakers routinely used Swiss mainsprings, balance spring and jewels. This movement has only 7 jewels, but it has a Swiss balance and balance spring, and not just ordinary ones. They are in fact a Paul Perret nickel steel compensation balance spring and an uncut monometallic balance made of maillechort, a nickel alloy that resembles silver in appearance.
The photograph shows the uncut balance and white metal alloy Paul Perret balance spring. Possibly the absence of train jewels was in order to keep the cost of imported materials to below sixpence.

John Troup & Sons
This company was established in the early 1840s by John Troup at 36 Hatton Garden, in London's jewellery quarter, as a watch and clock maker and jeweller. Troup was joined in the business by his sons Alexander James and Frederick William, when the business was named John Troup & Sons. In 1870 the business was described as a wholesale jeweller. The premises has a small street frontage but stretches back a long way and today houses 18 independently owned jewellers booths. It seems likely that the front of premises was used as a retail shop with a wholesale business at the back. In 1903 a branch was opened at 105 Spencer Street, Birmingham.
In 1907 the business and stock was sold to H. Williamson Ltd for £35,000.

Williamson Wristwatches
Although wristwatches had been used by British military officers since the 1880s, H. Williamson Ltd. was one of the first in the UK to recognise the important new market for wristwatches that arose during the Great War.
The 1916 Annual General Meeting of H. Williamson Ltd. was told that “ The public is buying the practical things of life. Nobody can truthfully contend that the watch is a luxury. In these days the watch is as necessary as a hat - more so, in fact. One can catch trains and keep appointments without a hat, but not without a watch. It is said that one soldier in every four wears a wristlet watch, and the other three mean to get one as soon as they can. Wristlet watches are not luxuries; wedding-rings are not luxuries. These are the two items jewellers have been selling in the greatest quantities for many months past.” (Emphasis added.)
The advert reproduced here for the Wristlet Astral dates to 1916. The watch is said to have a screw back and bezel case; these were made by the Dennison Watch Case Co.. Although Williamson were clearly enthusiastic about the prospects for wristwatches, English made Astral wristwatches are not common.
The movement was stamped “Warranted English”, but without this it could easily be taken for a Swiss made movement. It is essentially a Swiss watch made in England using Swiss machinery, with a Swiss straight-line lever escapement and exposed winding wheels, Swiss mainspring, balance spring, balance and jewels. It had only seven jewels in the escapement, no doubt to keep the cost of the imported components beneath the sixpennyworth limit the train bearings were not jewelled. It would be interesting to know what these retailed for, I am sure they were much more expensive than a Swiss made watch with a better 15 jewel movement. It is no wonder they are rare!

H. Williamson Liquidation
Following the financial crash of 1929 and the subsequent world-wide depression in the 1930s, H. Williamson Ltd. became insolvent in August 1931. The business continued to operate as before while the liquidators attempted to sell the assets.
A joint-stock company "Büren Watch Company SA" was formed in Büren an der Aare on 15 July 1932 for the purpose of acquiring the watch factory "H. Williamson Ltd. Buren Watch Co" and all its assets and goodwill. The purchase agreement was dated 19 July 1932. The board of directors were appointed at a constitutive general assembly on 23 August 1932. The directors included William Edward Tucker, ex joint managing director of H. Williamson. Tucker was appointed sales manager and by 1934 had travelled three time round the world selling Büren watches. The Swiss company was bought by the American Hamilton watch company in 1966.
The Coventry company Rotherham & Sons became the British agents for watches made by the Büren Watch Company SA in September 1932.
Williamsons made clocks and watches with the name Astral and, in the 1920s, electrically wound car clocks with the name Empire. A branch of Williamsons trading as “English Clock and Watch Manufacturers” was taken over by Smiths, who continued producing clocks with the name of Astral until 1955.
