If anyone can help me identify the hallmark, (presumed) date stamp and maker’s mark on one of my pocket watches, I’d be very grateful. I can see that the case is Sterling silver but can’t find the hallmark anywhere. The maker’s mark is clearer on the inside of the dusty cover (second pic). Many thanks in advance.
It’s a London import mark for the assay year 1913/14. The sponsor’s mark, GD, is that of Dimier Brothers, GD being the initials of Georges Dimier.
Many thanks indeed, Phil: much appreciated.
