The IWC 37522 watch movement, used during the period of 1975-1978, features an integrated automatic gear within the movement, a departure from the conventional method of attaching it to a manual-wind calibre. Additionally, it incorporates indirectly driven minute and second hands, allowing for a durable rotor bearing while maintaining a low profile. This movement is equipped with the following functions: automatic winding, a sweep second hand, and a quickset date feature.
