Watch bands can be sized to fit 7.5-inch to 8.5-inch wrists. Extra links are available through the manufacturer. (We do not provide this service.) 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.
