To power your watch, use the crown (winder knob) by rotating it in a clockwise direction at least 40 full rotations for full power equivalent to approximately 40 hours of continuous operation. You cannot over power the watch so it is ok to continue winding beyond 40 rotations. If you wear your watch throughout the day the automatic rotor contained in your watch movement will rotate with the movement of your wrist. This gentle movement of the automatic rotor will ensure that the power in your watch is maintained to at least the level that you achieved by winding the watch with the crown.
