Keep your watch wound!A watch winder is a device with an electrical motor to wind your watch when you are not wearing it. The power reserve of automatic watches is limited and they will run down in two or three days if you stop wearing them or winding them up. When your watch stops you have to reset time and wind it up. If your watch has additional functions (like date, moon phase display, perpetual calendar), resetting them may take a lot of time and require certain skills. With an automatic watch winder, you can keep your watch wound and ready to go!Watch winder description: Exterior finish: High-gloss piano lacquer; Interior lining: PU leather; Maximum watch case diameter: 2.4 inches (60 mm); Warranty: 1 year; AC power adapter included.The watch winder has a Motor-Stop option.
