A great looking early vintage wristwatch cased by Francois Borgel with a screwback case. The case is a oxagonal design used by many early watch companies, there is no maker on the movement but it looks to be of a high grade. If anyone has any idea on the maker I'd be interested to hear from. The case is an 8 sided version of the Taubert patent decagonal case, which has 10 flats on the screw back and bezel that are the origin of the name Working as it should and in good condition for... its age. Please inspect photos for condition. Feel free to make an offer.
