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 Rotorwind 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. 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.
