The Felsa 700N watch movement is equipped with a pin-lever escapement and features a sophisticated excenter self-winding mechanism with just one gear stage. It incorporates an excenter on the rotor arbor that controls a lever, which in turn drives a ratchet wheel through two clicks. On the dial side, a planet differential gear transmits the combined power from both automatic and manual winding, effectively achieving different gear ratios and ensuring the independent operation of both winding sources. This movement offers automatic winding, sweep second, and date functions. It was introduced around 1972.
