The Langendorf 1145 watch movement is an automatic movement with a sweep second function and a quickset date. It was used during the period 1968-1972. Notable features include the Triovis micrometer regulator, a low-profile design enabled by the integration of the indirectly driven minute and automatic gear into the movement, a ratchet on the dial side, a crown mechanism with a rocker bar, and a relatively small rotor ball bearing. The exact differences between the Movado 407 and 408 movements are not known.
