English English HOW TO USE This watch is an automatic watch equipped with a manual winding mechanism. • When the watch is worn on the wrist, the motion of the wearer's arm winds the mainspring of the watch. • If your watch is completely stopped, it is recommended that you manually wind the mainspring by turning the crown. ● How to manually wind the mainspring by turning the crown 1. Slowly turn the crown clockwise (the 12 o'clock direction) to wind the mainspring. * Turning the crown counterclockwise (the 6 o'clock direction) does not wind the mainspring. 2. Wind the mainspring until the power reserve indicator shows a full-wound state. The second hand will start moving. 3. Set the time, day and date before putting your watch on the wrist. * To check the winding state of the mainspring, refer to "HOW TO READ THE POWER RESERVE INDICATOR " on page 16. * There is no need to turn the crown further when the mainspring is fully wound. But the crown can be turned without damaging the watch mechanism. * Once the watch is wound up fully, it operates for about 45 hours. * If the watch is used without being wound up fully, gain or loss of the watch 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 like a clock, for example; be sure to wind it up fully every day at a fixed time. * If you use a watch that has stopped with the mainspring unwound, winding the mainspring with the crown will not start the watch immediately. That is because the mainspring torque (force) is low at the beginning of its winding due to the characteristics of mechanical watches. The second hand starts to move when a certain degree of strong torque is reached after the mainspring has been wound up. However, swinging the watch from side to side to forcibly turn the balance can start the watch sooner.
