Zenith

Swiss Watch Fair 1967 BF 40
This ladies’ watch is equipped with a new extra-slim self-winding movement. The movement of the rotor is coupled directly to the gear train by means of planetary differential gears (shown)which select the energy needed to run the watch, storing the balance in the barrel. This system does away with the reduction-gear train between the rotor and the barrel. With direct-action centre seconds hand. (ZENITH)
