The General 64 watch movement was manufactured during the period from 1938 to 1954. It features a Breguet hairspring and incorporates the Calendograf, a calendar module available on the 470 movement. The watch movement is a manual wind mechanism with a sweep second hand. Additional functions include day, date hand (set by a pusher at 4 o'clock), and month (set by a pusher at 2 o'clock). The inclusion of a sweep seconds hand and calendar provide added functionality to the timepiece.
