Power Reserve In Your Seiko Kinetic Watch - Seiko KINETIC AUTO RELAY 5J21 Instructions Manual

* 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 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
therefore, this watch does not require battery replacement.
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.
