The A Michel 522 watch movement features a ratchet on the dial side and a crown mechanism with a rocker bar. Its shock protection is provided by elastical spiral-shaped balance spokes. Additionally, it is worth noting that the train and hand gear are separately driven by the barrel. The movement offers various functions, including manual wind, sweep second, date, sweep seconds, jeweled lever, and a calendar. This movement was predominantly used around the 1960s.
