English * To check the winding state of the mainspring, refer to "HOW TO READ THE POWER RESERVE INDICATOR " on page 15. * 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. 10 English U AT 5 7 23 21 HOW TO SET THE TIME, DAY AND DATE (FOR CAL. 6R20/6R21/6R24/6R27) • Check that the watch is operating, and then set the time, day and date. * In 6R27, there is only a date display. • The watch is provided with a day and date function and is designed so that the day and date changes once every 24 hours.
