ORBITA SPARTA 1 OPEN WATCH WINDER BLACK
The Sparta One watch winder will maintain your self-winding watch in optimum condition. The stand-alone winder is activated every 10 minutes with a series of oscillations that mirror the natural movement of your wrist. The patented RotorwindÛ system initiates the first oscillation only, with each succeeding one powered by gravity. This self-regulating system eliminates any risk of damage due to over winding and will keep the batteries operating for over two years. Uses two 1.5 volt batteries.
