My grandmother, God rest her soul, recently passed away and I, as the "watch guy" in the family, received as part of her possessions a lady's Villereuse mechanical wristwatch. I know nothing about this brand and have seen very little here or on the Web about it.
It also has the smallest mechanical movement I've ever seen. It's photographed here on graph paper with 1/4" scale:
Now, what I read here is that "G. Monnin" was a French watch maker that was somehow affiliated with Heuer. That said, the movement is stamped "Swiss" and the dial reads "Swiss Made". Any help in identifying and dating this watch would be greatly appreciated.
As an aside, watch runs fine and is keeping great time!
