The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a good quality 17-jewel hand-winding movement which is working nicely. The movement carries the letters KOS which is the American import mark for Paul Buhré.
Petersburg, Russia. His son, Paul Buhré, was a skilled watchmaker and supplied watches to the Imperial Court of Russia. Paul Buhré maintained retail outlets in St Petersburg and Moscow, supplying the railways and Russian government. In 1880, Paul Girard-Gabus, an established watchmaker in Le Locle, Switzerland, opened a dedicated workshop there for Paul Buhré.

The movement is also signed with the name Charles Kastner, he would have been the original importer of the watch.
The watch measures 21.5mm excluding the winding crown (23.5mm wide across the lugs), and 25mm high excluding the lugs. The case is 10k rolled gold while the case back is stainless steel. The case is in beautiful condition.

Back in the 1950s, this would have been a man’s watch but, with today’s fashions, it would suit a man with a slimmer wrist, or a lady.
The curved lens is in lovely condition too.
The dial is signed with the brand name Krystal. It is in very nice condition with original hands.
A new leather strap has been fitted.
The watch comes in its original Ivorex box which is in super condition.
