I have been researching the history of the firm of François Borgel, which later became Taubert & Fils, for several years, and I am now writing my information up as an article for the NAWCC Bulletin.
Borgel and then Taubert & Fils used the trademark of FB and a Geneva key, like this:
I know that the firm supplied watch cases to Longines, Rolex, Mido, Movado, West End and Patek-Philippe. If you have a branded watch with the FB-key trademark in the case back which is <u>not</u> one of these brands, then I would like to hear from you!
Please either post some pictures here, or pm me. If you are prepared to let me use your pictures in my article, that would be even better. I always acknowledge contributions.
Thanks for any help!
