This pebbled full grain genuine leather watch winder is an indispensable tool for every automatic watch owner. It is vital to keep your automatic watch constantly wound with watch winders, as a stagnant automatic watch will eventually degrade in accuracy. This watch winder runs off an AC adapter (included) or 2 3V-batteries (not included) and offers 4 rotation options and settings to keep your automatic watch in optimal condition. LED light illumination changes color when the batteries need to be replaced. The plush cushion within the watch winder provides the versatility to store small or large watches. The ROYCE Leather watch winder is designed to be compatible with most watch brands; rotation adjustment and precise timers provide the control you need to keep all your watches ready to wear and prevent having to reset the time or date when changing watches.
