Using your Wolf Cub Single Watch Winder is easy. First, open the cover and place your watch in the rotator drum. The lock - in dynamic cuff will secure it for you. You can choose to power it using the included universal AC adapter or AA batteries (you'll need to buy the batteries yourself). Remember, lithium batteries last longer. Once powered, the winder will start with a 10 - second delay and rotate at 900 TPD in a bi - directional mode. There are pre - programmed pause and sleep phases. When not in use, keep it in a dry place. Clean the vegan leather with a soft, dry cloth. Don't use harsh chemicals as they may damage the leather. Check the batteries regularly if you're using them, and replace them when they run out.
