http://www.bestwatchwinders.com/single-watch-winders.htm - single watch winder Factory-fitted with 2 ORBITA Lithium "D" cell batteries which provide a minimum of 5 years guaranteed operating life.These unique Orbita Sparta watch winders gently swing the watch instead. Every 10 minutes , the internal control microprocessor signals the drive motor to make a single turn, causing the watch to swing back and forth for several oscillations just as it would if it were being worn on the wrist.<br /><br />The oscillating winding action of the ROTORWIND winder is totally self-regulating and there is absolutely no chance of damaging an expensive watch by over-winding. Each and every single watch winder component has been designed and field-tested to insure long and trouble-free operation. Single and Dual watch winder models available.
