The Longines 22AS watch movement is a detached manual wind movement that operates with either 18000 or 21600 A/h. Only samples with 21600 A/h are known, and the movement is not recorded in movement catalogs. The meaning of the signature HJP instead of HPP on these samples remains unknown. Further differences in the movement are not currently known. The movement incorporates several functions, including automatic winding, sweep second hand, and a date feature that can be set by changing 20-24 hours. The Longines 22AS movement was commonly used around the 1970s.
