This Volta double watch winder features a rustic ebony/rosewood finish with a black leather interior and is part of the Rustic Collection. The inside portion of this winder is lit by a white LED light that beautifully showcases the watch that is mounted onto the winder. This winder can be locked using the supplied key to ensure the safety of your prized possessions. Each of the watch mounts is powered by its own high quality and ultra-quiet Japanese Mabuchi motor. The winder is powered by a supplied 110/240v adapter. To control the motor of the winder, you will find an LCD screen on the inside of the winder. Using the buttons to the right of the screen, you can control the revolution direction and the speed (TPD) of the winder. You are able to select a clockwise setting, a counterclockwise setting, or a combination of clockwise and counterclockwise revolutions. With this Volta winder, you are able to select a speed (TPD) setting of 650, 900, 1350, or 1800 revolutions, so you will definitely be able to find the right setting for your specific watch.
