This budget-priced winder is compact and free-standing. This version is finished with jet-black, fully grained faux leather.
Each unit is fitted with rubber feet to prevent sliding or marring polished surfaces. Mounting cup and cushion are easily removed to facilitate loading and unloading, and to provide access to the mode-changing switch.
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 (click here for patent details). 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.
Factory-fitted with 4 ORBITA Lithium "D" cell batteries which provide a minimum of 5 years guaranteed operating life at the normal 10-minute winding cycle. Even longer life may be accomplished using the 15-minute mode, depending upon the watch's winding characteristics. Both winding heads are individually powered and switched. Perfect for use in safes and vaults, the SPARTA 2 OPEN LITHIUM is both compact and lightweight.
