Return To ShopThe Cyma Tavannes 415KA watch movement was manufactured from 1934 to 1942, with a total production of 531,500 units. It features a bimetallic screw balance and a Breguet hairspring. The safety barrel design incorporates a ratchet wheel and barrel coupled to the barrel staff using squares, and includes a joint spring core. This design reduces bearing pressure and prevents damage in the event of a breaking spring striking the barrel.
