Unlike other watchwinders which rotate a watch in order to wind it, the unique SPARTA 1 watchwinder gently swings the watch instead. Every 10 minutes the internal control micro-processor signals the drive motor to make a single turn, causing the watch to swing back and forth for several oscillations. The oscillating winding action of the SPARTA 1 watchwinder is totally self-regulating and there is absolutely no chance of damaging an expensive watch by over-winding.
