Blog: Sponsors Mark A9M
Date: 17 March 2022Copyright © David Boettcher 2006 - 2022 all rights reserved.
I make additions and corrections to this web site frequently, but because they are buried somewhere on one of the pages the changes are not very noticeable. I decided to create this blog to highlight new material. Here below you will find part of one of the pages that is either completely new or I have recently changed or added to significantly.
The section in this blog is about a series of sponsor's marks that have been a mystery for many years. Many watches from the late 1920s onwards are seen with Glasgow Assay Office hallmarks with a sponsor's mark of the initials A and M separated by a number or symbol, all incuse with no surround. Unfortunately, when the Glasgow Assay Office office closed in 1964 many of the records were lost or destroyed and there are no records of who entered these sponsor's marks at the Glasgow Assay Office.
Although the Glasgow Assay Office records are lost, the Edinburgh and Dublin Assay Office databases each include an A5M incuse mark. The punches were registered on 3 March 1931 and 17 September 1934 respectively. The registrant who entered the marks is recorded as J Veron [sic] Grauer & Company [Watch Importers] La Chaux de Fonds, Switzerland. From this evidence and the unique nature of the marks, it can be inferred that all the sponsor's marks consisting of the initials A and M stamped incuse with no surround and with a number or symbol between the letters were entered at the Glasgow and other assay offices by Véron Grauer & Company. The same company also entered a number of sponsor's marks consisting of the letters J and W separated by symbols such as trilobes and swastikas.
The number or symbol between the letters may have been used for administrative purposes, to identify which manufacturer each watch case belonged to. Recently a gold watch case with Glasgow import hallmarks and the sponsor's mark A9M has been seen with the Poinçon de Maître the Swiss watch case making company C. R. Spillmann & Co SA. This suggests that Véron Grauer used the A9M mark to identify cases made by C. R. Spillmann & Co SA.
To further this aspect of the research, if you have a watch case with British import hallmarks, a Swiss Poinçon de Maître and the sponsor's mark is the letters A and M, or the letters J and W, separated by a number or symbol, please get in touch.

AxM and JxW: J Véron Grauer & Co of Geneva
A star M
Some watch cases with Glasgow Assay Office import hallmarks have a sponsor's mark of the letters A and M separated by a number, such as the A2M mark shown here, and others with the same letters A and M separated by a symbol, such as the star in the second image.
Examples of A2M, A5M, A9M, A10M, A11M and A✧M have been seen. They are all similar in style, made with by incuse punch with no surround.
There are also watch cases with Glasgow Assay Office import hallmarks with a sponsor's mark of the letters J and W separated by a symbol. There are a large number of these, at least 22, recorded on surviving Glasgow Assay Office punch record plates.
Unfortunately, the records for the Glasgow Assay Office were mainly lost when the office closed in 1964 and there are no surviving records of who entered these marks. However, although the Glasgow Assay Office records have been lost, some punches identical to those entered at the Glasgow Assay Office were entered at the Edinburgh and Dublin assay offices, for which records do exist and from which it can be inferred who entered the same marks at the Glasgow Assay Office.
If you have a watch case with one of these sponsor's marks, either A(number)M, A(symbol)M, or J(symbol)W, or something else along these lines, I would like to see a photograph please!
A (number) M and A (symbol) M
Although the Glasgow Assay Office records are lost, the Edinburgh and Dublin Assay Office databases each include an A5M incuse mark with no surround. The punches were registered on 3 March 1931 and 17 September 1934 respectively. They were entered by J Véron Grauer & Co of Geneva.
From this it seems reasonable to infer that the identical A5M mark was entered at the Glasgow Assay Office by Véron Grauer & Co, and by extension that all of the similar “A (number) M” and “A (symbol) M” marks, incuse with no surround, that were entered at the Edinburgh, Dublin and Glasgow assay offices were entered by Véron Grauer & Co.
J (symbol) W
J swastika W
It is known from surviving Glasgow plates bearing registered punch marks that at least 22 similar punches were entered at the Glasgow Assay Office with the initials JW stamped incuse with no surround and with a symbol between the letters such as a heart ♡, diamond ♢, triangle △, square ▢, equals sign =, swastika, etc, etc.
The image shows one of these sponsor's marks with the swastika 卍, an ancient religious icon. The case has Glasgow Assay Office hallmarks for nine carat (·375) gold, the date letter is the "g" of the Glasgow hallmarking year from July 1929 to June 1930.
The Dublin Assay Office records include a sponsor's mark of J W incuse with a trilobe symbol between the letters, the same as the one shown in the image with Glasgow Assay Office hallmarks, so it seems reasonable to infer that the identical J trilobe W punch was entered at the Glasgow Assay Office by J Véron Grauer & Co.
By extension, it seems at least plausible to assume that all the similar “J (symbol) W” punches were also entered at the Glasgow Assay Office by J Véron Grauer & Co. It also seems possible that the mark was intended to be based on the initials J and V, but when the punch cutter was instructed, the letters V and W were mixed up due to different pronunciations.
The earliest record of a J (symbol) W punch is 7 Apr 1928 at the Dublin Assay Office.
J Véron Grauer & Cie
J Véron Grauer & Cie of Geneva were carriers who specialised in transporting products of high value such as watches and jewellery, and also in customs clearance in many countries. They entered these sponsor's marks so that they could act as assay agent for a number of different Swiss watch case manufacturers.
The number or symbol between the letters was used most likely used for administrative purposes, to identify which manufacturer each watch case belonged to. Watch cases were submitted in large batches for hallmarking and could not have labels or any other means of identification attached to them, so the sponsor's mark is the only means of identification.
A9M with PdM2 No 136
The sponsor's mark A9M has been seen in a nine carat gold case with Glasgow Assay Office import hallmarks for 1930 to 1931 and the Poinçon de Maître of a Hammer with Handle with the registration number 136 that was issued to the Swiss watch case making company C.R. Spillmann SA. If there are other cases with the same A9M sponsor's mark and a Hammer with Handle with the registration number 136, that would support the theory. If you have such a case, please let me know.
It appears that Véron Grauer were performing the same role as assay agent for Swiss watch case manufacturers as Stockwell & Co. This involved registering punches at British assay offices, supplying these punches to Swiss watch case makers, transporting watch cases to Britain, submitting them for assay and hallmarking and then returning the hallmarked cases to the case maker in Switzerland.
The mark with a star between the A and the M, shown in the second image, is in a case with Glasgow Assay Office import hallmarks which also has the GS sponsor's mark of Stockwell & Company. Véron Grauer was probably also part of the continent wide network of shipping agents including Messageries Nationales Express and the Messageries Anglo-Suisses that Stockwell & Co. also belonged to.
Véron-Grauer also entered a mark AK incuse within an incuse rectangular surround at the Edinburgh Assay Office in 1931.
Véron Grauer & Co still exists as a logistics company in Switzerland, the specialised valuables transport branch of the Deutsche Post DHL group, and traces its history back to 1867.
At one time it was thought that the J (symbol) W punches were entered by James Weir, who did enter some JW sponsor's marks. Philip Priestley records two sponsor's marks that are known to have entered at the Glasgow Assay Office by Weir; J.W. incuse with no surround, which is annotated in the records as “Watch Case Punch”, and J.W in cameo within a heart shaped surround. There are a number of other punches known to have been entered by Weir that Philip did not record because they are not recorded as watch case marks. It seems likely that JW punches without anything between the initials, especially those entered or used before 1928 and those in cameo, were entered by James Weir.
