Breguet 187H

Breguet 187H is a discontinued manual-winding caliber introduced in 1950. It is a historical mid-20th century movement that was not manufactured in-house by Breguet, but rather based on a ebauche supplied by Peseux, a prominent Swiss movement manufacturer. This practice was common among watchmakers during this era, where firms would often use purchased base movements and finish them to their own quality standards. The caliber reflects Breguet's approach to offering reliable timepieces in the post-war period.
