The caliber 12-400 stamped with the Geneva Quality Hallmark is rhodium-plated with fausses côtes decoration and a Gyromax balance adjusted for heat, cold, isochronism, and 5 positions. It has a straight-line lever escapement, a shock-absorbing mechanism, and a self-compensating Bréguet balance spring with a micrometer regulator.
