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 rhythmically at a rate of twice
a second, 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.
● If you find the second hand moving at two-second intervals after swinging the watch approximately 500
times, swing it further until the second hand moves at the normal 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.
● 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 IN YOUR SEIKO KINETIC WATCH
● Precaution on see-through case-back models:
If your watch has a glass case back, do not expose the case back to strong light such as direct sunlight
or an incandescent light at close range, as this may temporarily increase the power consumption of the
watch circuit, thus reducing the power reserve in the KINETIC E.S.U. This condition, however, will be
corrected when the case back is turned away from the light.
ENERGY DEPLETION FOREWARNING FUNCTION
● The watch remains accurate even while the second hand is moving at two-second intervals.
● If the stopwatch continues to be used after the second hand starts moving at two-second intervals, the
movement of the stopwatch hands may become unstable immediately before the watch stops
completely.
