The Movado 118 watch movement was developed between 1950 and 1954. It features a Breguet hairspring and was the first automatic movement with triple calendar functionality. The movement includes functions such as automatic winding, sweep seconds, day of the week display, a date hand that can be set using a pusher at 8 o'clock, and a month display that can be adjusted using a pusher at 9:20 o'clock. It is a mechanical movement.
