Swiss Poinçons de Maître

Copyright © David Boettcher 2006 - 2017 all rights reserved.

In the 1920s a formal registration system was introduced for Swiss watch case makers, to provide traceability for watch cases made of precious metals back to the actual maker. This required all precious metal watch cases made in Switzerland to carry a mark to identify the case maker. In Swiss the mark is called the Poinçon de Maître, which is literally the "Punch of the Master" but is usually referred to in English as a Collective Responsibility Mark. I rather like the Swiss term, so I will stick to using that.

Watch manufacturers didn't usually want the name of the case maker appearing in the back of their watches because the case maker was normally a separate company that supplied several, or even many, different watch manufacturers with cases. To comply with the law a system of marks and code numbers was devised by the Swiss watch case manufacturers, with different symbols representing the different case making regions of Switzerland, principally Geneva and the Neuchatel and Jura regions. The marks are called collective responsibility marks because each one was used by more than one member of the association.

These marks are usually seen in gold, platinum or palladium cases. Although provision was made by the Swiss watch case makers association for silver cases to be marked, these are rarely seen.

Origins of the system


La Fédération Horlegère Suisse, 5 May 1926

The system was introduced in the mid 1920s. I don't know exactly when, and the current Swiss precious metal control authority doesn't know either. Before 1934 the system was administered locally in the individual Swiss cantons and when it was centralised in 1934 the previous records were not maintained.

The extract from La Fédération Horlegère Suisse from May 1926 shown here describes how the Poinçon de Maître are registered at the assay office or "bureau de contrôle" of the canton or arrondissement where the manufacturer operates or resides. This clearly shows that the system of poinçon de maître or collective responsibility marks for watch cases was certainly in use by May 1926.

The extract also says that the bureau de contrôle is responsible for the guarantee marks that are struck on the work that show the "dureé du plaqué" i.e. the duration or expected lifetime of plating. This is for gold filled or gold plated cases.

I have seen a nine carat gold watch case with London import hallmarks for 1924/1925 without a Poinçon de Maître. The earliest date the the London hallmark could have been struck was at the end of May or beginning of June 1924, so the system must have been started after that date but before May 1926.


Louis Lang advertisement with PdM January 1925

The earliest mention of a Poinçon de Maître that I have seen to date is in the advert by Louis Lang from January 1925. The round topped shield containing the letters "L.L."" is clearly identified as a Poinçon de Maître. This mark does not follow the scheme of the 1934 registration but is instead more like a normal trademark. It appears that initially manufacturers could register marks like this either in place of or in addition to one of the five collective responsibility marks.

The advert says that the company of Louis Lang manufactures watch cases in gold plate (plaqué or) that are guaranteed for 5, 10 or 20 years, and also cases in silver, "métal" and steel (acier). I think that in this context métal means nickel. It is strange that they do not mention making gold cases, only gold plated cases. The use of a Poinçon de Maître on gold plated cases ties in with the statement in the 1926 notice above about the mark guaranteeing the duration of the plating. A later Act in 1934 makes no mention of gold plated cases, only gold and platinum cases.

There are gaps in the 1934 list, most of them probably due to the registered company going out of business between the origin of the systems and the centralisation in 1934. Some of these gaps are quite large, for instance the list of Poinçons de Maître No. 1, the hammer head, contains only three numbers below 100, numbers 2, 11 and 26. This implies that the other 97 of the first 100 registrants had ceased trading by 1934.

The case of Poinçons de Maître No. 2, the hammer with handle, is even more mysterious. In the 1934 list there are only two entries, 115 and 160. The highest number that has been reported to me with a hammer with handle mark is 321. This implies that perhaps 319 companies on the original list had ceased trading by 1934. I don't think that was actually what happened, I think there was a reorganisation of the lists that left the hammer with handle mark redundant, but at the moment that is just speculation.

The 1934 Act

In 1934 a new Act was passed which required all the Poinçon de Maître marks to be registered at the Swiss Central Office for Precious Metals Control in Berne.

The responsibility marks shown in the section below were registered by the Fédération Suisse des Associations de Fabricants de Boîtes de Montres (Swiss Federation of Associations of Watch Cases Producers, or F.B. for short). The Federation changed its name in 1966 to called Union Suisse des Fabricants de Boites de Montre (USFB) (Swiss Union of Watch Cases Manufacturers). Later this was changed to the Union Suisse pour l'Habillage de la Montre (USH) (Swiss Union for Watch Casing). In 2006 it took the name USH-APIC, Union Suisse pour l'Habillage de la Montre et Association Patronale Suisse des Industries Microtechniques (Swiss Union for Watch Casing and Employers' Association of Industries Microtechnologies) and is now known as "apiah" (Association patronale des industries de l'Arc-horloger). It is based in La Chaux-de-Fonds.

Responsibility marks

The system of Poinçons de Maître used different pictographic symbols to represent the different case making regions of Switzerland, principally Geneva and the Neuchatel and Jura regions. The marks are called "collective responsibility" marks because each one was used by more than one member of the association. However, so that the individual members could be identified, each member of the association was allocated a registration number which they stamped in the mark. The gave traceability back to the specific manufacturer of a watch case as was required by law.

The responsibility marks are shown in the table below. They are usually very small and quite difficult to see, and are mainly seen on gold, platinum or palladium cases., although they do very occasionally turn up one silver cases, which No.3 and No. 4 were specifically intended for. Responsibility marks were not required by law on Swiss cases so their use was voluntary.

When stamped the XXX shown in the marks are replaced with a number that indicates the maker of the case. If you do find one in your watch case, then it is a simple matter to consult the tables of registered marks further down on this page and see who was the case maker.

No. 5Key of GenevaFor gold, platinum and palladium watch cases of minimum thickness 0.3mm made in Geneva.
No. 6ShieldFor gold, platinum and palladium watch cases of thickness less than 0.3mm made in Geneva.

The system and numbering pre-dates 1934, but the 1934 list is the only one we have available today and it has some gaps in it, presumably where the registrant no longer existed when the 1934 list was compiled. So it is possible to find these Collective Responsibility marks in watch cases that are earlier than 1934, and if the registrant is in the 1934 list, all well and good, but the gaps in the 1934 list are presumably where earlier registrants had gone out of business before the list was compiled.

Lists of the marks and registration numbers, together with the names of the watch case makers who the marks were registered to, can be found further down on this page. You can click on the picture of the mark or the live links in the table above to jump straight to the part of the list that you want to see.

Missing numbers

In addition to the large number of numbers missing from PdM number 2, the hammer with handle which I discuss in the "hammer with handle" mystery below, each of the lists has some numbers missing. If you have or see a watch case with one of the missing numbers, please let me know via my Contact me page.

The "hammer with handle" mystery


Hammer with handle No. 180

The hammer with handle mark is rather interesting because there are only two numbers listed in the 1934 list, 115 and 160. This seems to imply that there must have been a large number of companies with this mark at one time, but that they had all gone out of business before 1934. It seems unlikely that such a large number of companies would have gone out of business in 10 years and therefore I suspect that something else happened, but I don't know what.

An official description of the meaning and use of each of the marks that was supplied to me in 2011 by USH-APIC contains no reference to mark No. 2, the hammer with handle. Unfortunately this description is not dated.

The one thing that can be said for sure is that if your watch has a hammer with handle mark and the number on the hammer head is not either 115 or 160 then it must have been made between when the Poinçon de Maître system began, circa 1925, and 1934.

I have a Stauffer & Co. watch with the Hammer with Handle mark shown to the right. The watch case is 9 carat gold and has Glasgow import hallmarks for 1926 / 1927, further evidence that the Poinçon de Maître registration system was in use before 1934. As you can see it has a number 180 on the hammer head, but there is no record in the 1934 list of a company using this symbol with the number 180, so the maker of this case must have gone out of business between 1926 / 27 when this case was made and 1934 when the central list was compiled.

I asked USH-APIC and the Swiss Central Office for Precious Metal Control about this, but they have no records prior to 1934. If the numbers were issued consecutively starting with 1, like for the other marks, there may have been up to 180 companies, and possibly more, using the hammer with handle mark registered with the Cantonal Authorities outside Geneva in the mid 1920s when the Poinçon de Maître registration system was introduced.


No. 321, thanks to Glenn

If you have an example of a Poinçon de Maître of the hammer with handle that is not either 115 or 160, please let me know so that I can add the "unknown" manufacturers to the list. One day this might lead to something.

A correspondent sent me details of a lady's wristwatch with an 18K 0,750 gold case with Swiss head of Helvetia carrying the hammer with handle mark and the registration number 321 as shown in the second picture here.

The watch movement is marked Dueber Hampden Watch co, Swiss 2 Adj .15 Jewel, believed to be manufactured by the Venus Watch Co. of La Chaux-de-Fonds, Switzerland, dating approximately to the 1920s.

The registration number 321 is is far higher than any previous registration number that I had seen. I now think it is more likely that some reorganisation or consolidation of the lists of Poinçons de Maître took place in the 1920s, rather than the unlikely scenario of over 300 separate case manufacturers all going out of business in the space of a few years.

Poinçon de Maître No.1 : Hammer head

Where a number is missing from the table the registrant of that number must have gone out of business before the data was centralised in 1934. At the moment we have no way to know who that company was.

Where the date of "Radiation" or striking off is blank, the company was still in existence when this data was compiled in September 2007.

"Marteau sans manche" : Hammer without handle, or hammer head. For gold and platinum watch cases made in Switzerland outside Geneva.

Why do some of the companies have addresses in Geneva? Probably that was their headquarters, and they also had a factory outside Geneva.

Poinçon de Maître No. 2: Hammer with handle

The hammer with handle mark is rather interesting because there are only two numbers listed in the 1934 list, 115 and 160. This seems to imply that there must have been a large number of companies with this mark at one time, but that they had all gone out of business before 1934.

The one thing that can be said for sure is that if your watch has a hammer with handle mark and the number on the hammer head is not either 115 or 160 then it must have been made between when the Poinçon de Maître system began, circa 1925, and 1934.

This is discussed in greater detail in the section The "hammer with handle" mystery at the head of this page.

Where a number is missing from the table the registrant of that number must have gone out of business before the data was centralised in 1934. At the moment we have no way to know who that company was. If you have an example of a Poinçon de Maître of the hammer with handle that is not either 115 or 160, please let me know so that I can add the "unknown" manufacturers to the list. One day this might lead to something.

Hammer with handle or "Marteau avec manche".

Poinçons de Maître No. 3 and 4: marquee and crossbow

The lists under poinçon de maître No. 3, the marquee of the Fédération des Fabricants de Boîtes Argent (FFBA), and poinçon de maître No. 4, the arbalète or crossbow are identical up to entry number 48. Numbers 49 and 50 appear to have been "recycled", I have noted this on the list below. Other than this the two lists are identical so I have made one combined version here. The crossbow list stops at 50 with the exception of number 67 Manufacture Cartier La Chaux-de-Fonds, which is the same in both lists.

Where a registration number is missing from the sequence, the inference is that the registrant of that number had gone out of business before the data was centralised in 1934. At the moment we have no way to know who that company was. Where the date of "Radiation" or striking off is blank, the company was still in existence when this data was compiled in September 2007.

PdM 3: Marquee and also PdM 4, arbalète or crossbow.

Both marks used by Fédération de Fabricants de Boîtes Argent (FFBA) (federation of silver case makers), later Fédération Suisse des associations de Fabricants de boîtes de montre (FB) then Union Suisse des fabricants de boîtes de montre (USFB).

Only for silver watch cases made in the Swiss cantons of Neuchâtel and Jura.
