* It is not necessary to charge the watch fully, as it is charged automatically
while it is worn on your wrist.
Notes:
1. To charge the watch efficiently, swing the watch from side to side, making an arc of about 20 cm.
2. No additional benefit is obtained by swinging the watch more quickly or with greater vigor.
3. 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.
4. The watch is equipped with a system to prevent overcharge. Even if it is further swung after being
fully charged, no malfunction will result.
5. Wear the watch daily for at least 10 hours.
6. Even if the watch is worn on your arm, it will not be charged while your arm is not in motion.
● Power reserve guideline for the KINETIC E.S.U.
• You can estimate the power reserve accumulated in the KINETIC E.S.U. from the manner
in which you wear the watch.
• Using the manual power save function as often as possible is an effective way to conserve
the power reserve.
POWER RESERVE IN YOUR SEIKO KINETIC WATCH
● The electric energy generated while the watch is worn on your wrist is stored in the KINETIC
E.S.U. It is a power source completely different from conventional batteries for watches and
does not require any periodical replacement.
ENERGY DEPLETION FOREWARNING FUNCTION
The watch has been charged fully at the factory, and the power save function will keep
the built-in IC computing the time for up to four years. Normally, therefore, it is not
necessary to charge the watch manually by swinging it. If you should find the second
hand moving at two-second intervals, however, charge the watch following the
procedure in “● How to charge the watch”.
● When the second hand starts moving at two-second intervals instead of the normal one-
second intervals, the watch will run down in approximately 12 hours.
● If the second hand starts moving at two-second intervals when the power save function is
turned off by swinging the watch, the power reserve may have become depleted to an
extremely low level.
In those cases, charge the watch following the procedure below.
1. Swing the watch from side to side approximately 500 times.
* Swing rhythmically at a rate of twice a second.
* If the second hand still moves at two-second intervals after the watch is
swung 500 times, swing it further until the second hand moves at one-
second intervals.
2. Swing the watch approximately 200 times further to reserve
one day of power.
