・To wind up the watch by turning the crown, turn it clockwise slowly. The watch cannot be wound by turning the crown counterclockwise.
About 40 turns of the crown will wind up the watch fully. Please note that the crown can be turned even after the watch is wound up fully.
・Once the watch is wound up fully, it operates for about 50 hours. (If the watch is used without being wound up fully, gain or loss of time may result. To avoid this, wear the watch for more than 10 hours a day.) If the watch is used without wearing on the wrist ; if it is used on the desk, for example : be sure to wind it up fully every day at a fixed time.
