SGT - Quartz 0510 - Société des Garde-Temps

European Watch Clock and Jewellery Fair 1976 BF 323
This quartz watch features a very simple electronic time adjustment system. Instead of a crown, two setting buttons are recessed in the case. One is used to synchronise the watch with a time source to the exact second, the other for major corrections (time-zone changes, etc.). Other attractive features include a trimmer for rate adjustment, a battery providing over 2 years’ power reserve (30 months in fact) and its compactness: Ø 22 mm.
