Our new EVOlution watch winders feature an advanced winding mechanism. Unlike our traditional watch winders, which are wound by slow rotation, the EVOlution winders gently swing the watch. The mechanism will turn both clockwise and counter-clockwise in the same motion. Our revolutionary coil instrument powers the initial oscillation of the winding cycle and all subsequent oscillations use this momentum to power the device. Because of this advance technology, battery life is guaranteed for two years, which is ideal for storing your watches in a safe. An exciting, science-fiction inspired design in chrome and ebony. The mechanism is mounted in a chrome sphere suspended on chrome springs over an ebony wooden base which contains the battery compartment and control functions.
