Movement has not been cleaned or serviced, so selling as is for repair. But i did wind movement and it ran out in just under a day. A good cleaning and a bit of oil, and should be a good runner. Cannon gear does come off easy on the movement, but probably pinned in place with the hands. Marked Germany Rensie Watch CO. Inc. on spring cover. Measures 2 5/8th inches wide, just under 2 1/2 inches tall at the widest point of the plates. Roughly 1 inches center too center of winding arbor and hand shaft. Thanks for looing and please ask questions.
