Blog: Rolex sponsor's marks
Date: 27 April 2015Copyright © 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, so I decided to create this blog section to highlight new material. Here below you will find part of one of the pages that I have either changed or added to significantly.
The section reproduced here is from my page about Sponsor's marks. A sponsor's mark is a responsibility mark that must be impressed onto gold or silver items before they will accepted at a British assay office for testing and hallmarking. It identifies the person who takes responsibility, a meaning of the term "sponsor", if the item is found to be substandard. The mark is entered into the assay office records by a person who wishes to submit items for hallmarking, along with their details.
These are sometimes referred to as "makers marks", but this can be very misleading. It was never the intention that it would identify who actually made the item, which is why the term "sponsor's mark" is preferred today. This is especially so for imported items that were manufactured overseas, which were sent for hallmarking by an agent in Britain, but even in the case of British workers it can be misleading. Take for instance Paul de Lamerie, described as being the "greatest silversmith working in England in the 18th century"; he also subcontracted orders to other London workshops, striking the finished items with his own mark before sending them to be hallmarked.

W&D: Wilsdorf and Davis
W&D: Wilsdorf and Davis
W&D: Wilsdorf and Davis
This W&D in an oval shield with points top and bottom is the sponsor's mark of Wilsdorf & Davis, importers of gold and silver wares, first registered at the London Assay Office on 25 June 1907. A second punch with the same mark was registered on 13 August. The company of Wilsdorf & Davis is better known these days by a brand name that Wilsdorf created in 1908; Rolex.
The company of Wilsdorf & Davis was founded in London in 1905. Until 1907 they would have imported watches and other silver and gold items without having them tested and hallmarked by a UK assay office, but UK law changed in 1907 and from 1 June 1907 all imported gold and silver items had to be assayed and hallmarked at a UK assay office. This is the reason for the registration of the W&D sponsor's mark. Items imported from Switzerland by Wilsdorf & Davis before 1907 would have carried Swiss hallmarks. Once the UK law was changed, the Swiss authorities allowed items to be exported to the UK without Swiss hallmarks.
The registration of the two punches on dates so close together indicates that the second punch was required to keep up with the volume of work, rather than replacing a worn out punch, so Wilsdorf & Davis must have had two men working full time punching watch cases that were to be sent for hallmarking.
The following information is gleaned from Culme John Culme "The Directory of Gold and Silversmiths, Jewellers and Allied Traders, 1838-1914: From the London Assay Office Registers" Publication Date: 15 Oct 1987 | ISBN-10: 0907462464 | ISBN-13: 978-0907462460 Two volumes; the first with 4,000 biographies, the second with photographs of 15,000 marks taken directly from the London Assay Office Registers at Goldsmiths' Hall. . The partners in Wilsdorf & Davis were Hans Wilsdorf and Alfred James Davis. The address recorded at the registration of their punches was 83 Hatton Garden, later recorded on 1 November 1907 as moving to 85 Hatton Garden, EC1, then between 17 August 1912 and 25 August 1919 they are recorded at Stevenage House, 40-44 Holborn Viaduct, EC, where they are listed in 1913 as watch manufacturers and importers (TA: 'Wilsdorfs').
Wilsdorf & Davis are also recorded on 8 April 1915 at 15 Northampton Street, Birmingham, and also 3 Ruelle de la Fabrique, Bienne, Switzerland. They are recorded 25 August 1919 as having an office at 61 Rue Elfenau Gare, Bienne, Switzerland, in addition to their London office, and also as representatives of the Rolex Watch Co. Ltd. whose chairman was Hermann Aegler with Hans Wilsdorf and Alfred James Davis as directors and Harry Sedgley as secretary.
The same W&D sponsor's mark was entered at Birmingham in June 1909, at Chester in April 1912 and at Glasgow, although records of the date of the latter entry have been lost. These additional registrations allowed Wilsdorf & Davis additional freedom to either order items to be made outside London, or send items to be hallmarked at Birmingham, Chester of Glasgow if there were delays at one of the other assay offices, or if one office was cheaper than the others.
Although the sponsor's mark was not necessary on watch cases that did not require a British hallmark, it would have been convenient to arrange for the case maker in Switzerland to stamp the mark as the case was made. There was no reason why it should not have been stamped on watch cases that were not ultimately hallmarked in Britain, and it would have been easier to stamp all cases, whether or not they were destined for Britain. Therefore the W&D mark can be seen in watch cases without British assay office marks.
