The ETA 2341 watch movement, used during the period of 1960-1961, features a pin-lever escapement and indirectly driven minute and second hands which allow for a larger barrel. Its ratchet is located on the dial side, and the crown mechanism incorporates a rocker bar. Notably, this movement includes a shared barrel for both the watch and alarm functions. Additionally, it incorporates a device that provides 2.5 revolutions of the mainspring arbor for the alarm, with the clutch wheel functioning simultaneously as a ratchet. The noted functions encompass a manual-wind alarm and a sweep second hand.
