The Elgin 416 watch movement is a manual wind mechanical movement with a sweep second hand. It features a calendar module with several functions: the day can be set using a pusher at 10 o'clock, the date-hand can be set using a pusher at 4 o'clock, the month can be set using a pusher at 2 o'clock, and the moon phase can be set using a pusher at 8 o'clock. This movement was commonly used around the 1950s.
