Here is a look inside a typical SPARTA watch winder with the patented ROTORWIND® system: |

Unlike other watchwinders which rotate a watch in order to wind it, these unique watchwinders gently swing the watch instead. Every 10 minutes (standard program), 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. The 15-minute program (extended program) available on all battery operated versions allows many watches that wind in both directions to remain fully wound while on the winder, increasing battery life by as much as 50%. All battery operated SPARTA winders are fitted with high-energy, factory-installed, LITHIUM batteries which are guaranteed to provide a minimum of 5-year battery life. In addition, each SPARTA winder carries an iron-clad 5-year product guarantee. 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. Each and every winder component has been designed and field-tested to insure long and trouble-free operation. Even the heaviest automatic wristwatch "swings" silently and effortlessly, supported by the oversized steel drive shaft, which is fitted with four low-friction, precision-groundball bearings. That's why we can offer ORBITA's iron-clad five year materials and workmanship guarantee for each and every American-made SPARTA watchwinder and that includes a five year battery service life guarantee on all SPARTA Lithium powered winders. |
