Unlike other watchwinders, which rotate the watch in order to wind it, the budget- priced SPARTA Watchwinder gently "swings" the watch instead. Every 10 minutes throughout the day, the internal micro-processor activates the drive motor, causing the watch to swing back and forth for several oscillations just as it would if it were being worn on the wrist. The oscillating winding action of the SPARTA Watchwinder is totally self-regulating and there is absolutely no chance of damaging an expensive watch by over-winding. A semi-circular rotor, attached to the back of the mounting cup, is the "heart" of the patented ROTORWIND™ system. Made from a dense, non-magnetic iron material, it is supported by two free-turning precision ball bearings, thus enabling the heavy mass of the rotor to produce the "back and forth" motion when the cup is raised and then released from the 12 o'clock position.
