Unlike other watchwinders which rotate a watch in order to wind it, the unique SPARTA 2  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 just as it would if it were being worn on the wrist.

The 15 minute program on battery  powered   winders (extended program) allows many watches that wind in both directions to remain fully wound while on the winder, providing increased battery life by as much as 50%.

The oscillating winding action of the SPARTA 2 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 each mounting cup, is the "heart" of the patented (click here for details)  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. Each head has it's own power switch and operates independently.

This budget-priced free-standing open model are is available in a stylish textured black leather-like material.  Rubber feet prevent slipping and protect delicate surfaces from scratching.

he watch to be wound  is easily mounted over a resilient foam cushion, which accommodates virtually any  size watch with either leather strap or metal bracelet.  The cushion fits snugly into the drive cup, making it impossible for the watch to fall as the cup swings back and forth during the winding cycle.  Both cups are easily removed to facilitate watch mounting.

The SPARTA 2 DC watchwinder is powered by two pair of 1.5 volt, "D" cell alkaline batteries, one pair  for each winder head (click image for enlarged picture).  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 two years without any need for a battery change.
