NOTES FOR USING THE WATCH
HOW TO CHARGE AND START THE WATCH
● To charge the KINETIC E.S.U. efficiently, swing the watch from side to side, making an arc of about 20 cm.
● No additional benefit is obtained by swinging the watch more quickly or with greater vigor.
● When the watch is swung, the oscillating weight in the generating system rotates to drive the mechanism.
As it rotates, it gives out a sound, which is not a malfunction.
● When the watch has been left untouched for more than one year after it completely stopped, the second
hand may not start moving at normal one-second intervals even if the watch is swung the number of times
indicated in “NUMBER OF SWINGS AND POWER RESERVE”. In this case, swing the watch further until
the second hand starts moving at one-second intervals.
● The watch is equipped with a system to prevent overcharge. Even if it is further swung after being fully
charged, no malfunction will result.
● Some models are equipped with an instant-start function, and the watch may start operating after it is
swung several times. For details, see “INSTANT-START FUNCTION”.
● It is not necessary to charge the watch fully, as it is charged automatically while it is worn on your wrist.
● Wear the watch daily for at least 10 hours.
● Even if the watch is worn on your arm, it will not be charged while your arm is not in motion.
POWER RESERVE INDICATOR
● The power reserve indicator provides only a general guideline of the duration within which the watch keeps
operating without needing to be charged.
● You can immediately press the button again to recheck the power reserve one more time. To do so a third
time, however, wait until the second hand resumes normal movement before pressing the button again.
● When the second hand moves at two-second intervals, the power reserve is very low and the indicator
does not function.
