Hello, I've got another vintage mystery on my hands...lol Hopefully you all enjoy sharing your knowledge as much as I do hearing it!
Below are a few pics of the watch movement, dial and case back inside. Incase the pics are bad (flash) the mainspring gear has 'Buren Gran Prix' written on it in blue. Buren watch co. is stamped on the movement, as well as '7 jewels', 'non adjusted', and 'WXC' which I believe is an importers code? On the inside of the case back, is stamped 'Buren watch co. S.A.' and 'swiss'. Then underneath of that is stamped 'Fond Acier' and 197662.
The outside of the case back is smooth, but I read somewhere that sometimes soldiers would 'rub out' the mililtary insignia so they could 'keep' their trusted watch.
Could this be a WWII watch? Any info is much appreciated as always!
