This watch is powered by automatic movement which means the winding of the spring occurs automatically when the wearer moves his/her 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.
