Vintage 1934 18k Solid Gold La Chaux-de-Fonds~BWC Incabloc Women's Swiss Watch.  Hallmarks on the back of case are the Helvetica head, 18K, 0.750, 105 inside a hammer-head (stands for Le Fils de Jules Blum/the son of Jules Blum); on the side of the case is another stamp of Helvetica Head with a "C" underneath it (stands for La Chaux-de-Fonds). BWC stands for Buttes Watch Co. - an obscure, but high quality firm which I believe is still making watches today. The leather/crocodile strap has been worn, and is in pretty good condition. The watch measures 20 mm in diameter, and the lug is 10 mm. The case is 9 mm thick...lots of gold in it. This is a very fine Swiss watch which I bought in a jewelry store in Europe. Weighs 17 grams including band.

This will come in a gift box.
