Using your Wolf Designs Viceroy Single Watch Winder is easy. First, place your watch in the lock - in dynamic cuff. It's designed to fit all wrist sizes comfortably. Next, choose your rotation settings. You can set the turns per day (TPD) between 300 and 1,200, and decide if you want it to wind clockwise, counter - clockwise, or both. There's also a 10 - second start delay option. For watches with a power reserve, use the power reserve setting which ranges from 6 to 72 hours in 6 - hour increments. This gives your watch time to release stored energy before winding. You can power the winder with the included universal AC adapter or use D - Cell/Lithium batteries (not included). When it comes to maintenance, keep the winder clean. Use a soft, dry cloth to wipe the vegan leather exterior. Avoid exposing it to extreme temperatures or humidity. If you're not using the winder for a long time, it's a good idea to remove the batteries to prevent any potential damage.
