Orbita Diy Single 3 V Rotorwind® Watch Winder Module
These individual modules make it easy for fabricators to design and build a custom winder system for a closet, safe or any special storage area. They are completely self-contained and operate on the low voltage provided by alkaline or lithium batteries. The oscillating winding action of these modules is totally self-regulating, and there is absolutely no chance of damaging an expensive watch by over-winding.
