Friend has sent me these pictures of a tiny Baume and Mercier watch that was given to a lady as a 21st birthday present about 70 years ago. I've asked for a movement shot, and asked about the metal (given the condition I'm presuming its solid gold?) I'm hopeful that the serial number might be of some use. The third picture is to show how small it is! Would B and M still service it?
I've zero idea of the quality of movements put into watches like these
