Sparta 2 Executive Watch Winding Box

From the manufacturers website:

Unlike other watchwinders which rotate a watch in order to wind it, the unique SPARTA 2  watchwinder gently swings the watch instead.  Every 10 or 15 (extended program) 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 just as it would if it were being worn on the wrist.

Top of the Sparta line, the Executive winder is offered in Charcoal Stingray and comes with a pull-out drawer for storing 6 other watches on pillows and/or other personal jewelry.

The SPARTA 2 Watchwinders are powered by two pair of "D" cell lithium batteries, one pair  for each winder head.  As the drive motor only powers the first oscillation of each winding cycle, with all succeeding oscillations totally powered by gravity, battery drain on the motor is minimal.  Hence, the SPARTA  2 Watchwinder is guaranteed to operate for a minimum of five years without any need for a battery change.
