This watch is powered by automatic movement which means the winding of the spring occurs automatically when the wearer moves his arm. However, it is recommended that you manually wind the watch at least once every two weeks. It is also important to adjust the time once a month as automatic movement can gain or lose a few minutes per month. This watch has a screw-down crown (knob) for setting the time. Screw-down crowns create a stronger seal against the case than a push-and-pull knob, giving the watch a greater water resistance factor. To unscrew the crown, grasp the knob and turn it counter-clockwise (towards you) a number of times until it releases. Then pull or push the crown into position to set the time, date, and other functions. To close the crown, press it against the case while turning in a clockwise direction.
