Abstract: At least one resurfacing system and at least one adjustment guide system for positioning a chuck holding a watch component relative to the resurfacing system. In example embodiments, the adjustment guide system includes one guide rail providing linear offset/distance and angular adjustment and guidance, or two perpendicular guide rails providing linear offset/distance and lateral position adjustment and guidance. Some embodiments include first and second resurfacing systems and a common rotary drive system that drives both the first and second resurfacing systems. The first resurfacing system can be a linear belt resurfacing system and the second resurfacing system can be a rotary disc resurfacing system. Some embodiments including the rotary disc resurfacing system have a metal rotary mounting disc driven by the drive system and a replaceable magnetic resurfacing disc that magnetically adheres to the rotary disc. Also disclosed is a method of resurfacing watches using these watch resurfacing devices.
