Poinçons de Maître, GENEVA Key, No.27
Oct 08, 2022,10:11 AM
When I was sorting out the data today, I found several vintage V&C which used caliber 458, the case manufacturer is GENEVA Key, No.27.
There were diamond-shaped hallmarks on the inside of the case, and I don't find any other Swiss watchmaker from the same period using a similar hallmark. Is this an exclusive logo for this factory? I cite information from the web(vintagewatchstraps).
The factory using the 27 code has changed its name several times. I am now collecting information and hope that some friends can improve more content.
