POWER RESERVE IN YOUR SEIKO KINETIC WATCH
The electric energy generated while the watch is worn on your wrist is stored in the
KINETIC ELECTRICITY STORAGE UNIT (KINETIC E.S.U.). It is a power source completely
different from conventional batteries for watches, and therefore, does not require any
periodical replacement.
The KINETIC E.S.U. is a clean and environmentally friendly power source.
Power reserve guidelines 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.
Wearing the watch continuously for 12 hours will accumulate approximately two
additional days of power reserve.
If you wear the watch every day for 12 hours for a month, for example, two additional
months of power will be reserved.
Full charge
When the watch is fully charged, the watch will keep operating for approximately
5 months. The duration of charge decreases gradually over time. The extent of decrease,
however, varies depending on the environment and condition of use.
Precautions for those only wearing the watch occasionally
If you use the watch only occasionally, it is likely that you will find the watch running
down when you decide to use it. Before wearing the watch, be sure to charge it sufficiently
following the procedure in “HOW TO CHARGE AND START THE WATCH”.
