FOR PARTS/REPAIR ONLY – The automatic movement does not run. And while the date and time can be set without issue and the original crown winds smoothly when it’s turned counterclockwise it unscrews. Additionally the case back gasket has deteriorated and needs to be replaced as does the crystal. Given these issues and considering that the movement shows no signs of ever having been serviced at a minimum a complete overhaul is required.
