Bold Black Sparta 1 Dc Winder w05521 - Orbita Rotorwind

Unlike other watchwinders which rotate a watch in order to wind it, these unique watchwinders gently swing the watch instead. Every 8 minutes - standard program (the 12-minute or extended-winding cycle, can be selected using the toggle switch located behind the mounting cup), 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.

Orbita oscillating winding. The oscillating winding action of the SPARTA winder 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.
