Power source (KINETIC E.S.U.)
・ This watch requires no periodic battery replacement as it is powered
by the exclusive secondary battery, which is completely different
from silver oxide batteries in conventional watches.
However, the repetition of charge and discharge cycles over a long
period of use may slightly shorten the continuous operating time of
the watch. (This will be affected by the conditions of use and the
environment where the watch is stored.)
・ This exclusive secondary battery is an environmentally friendly, clean
energy storage device.
