A. BEFORE USING
This watch is not powered by a conventional battery, but is powered by
converting light to electrical energy.
Once fully charged, the watch will continue to run for approximately 6 months
without additional charging. We do recommend exposing your watch to light
every day to ensure optimum performance. Always be sure to recharge the
watch before it stops.
Your watch features an Overcharge Prevention Function so there is no need to
worry about overcharging your watch.
A special energy storage cell is used to store electrical energy. This special cell
does not
require replacement and is a clean energy unit that does not use any
toxic substances.

Before using, be sure to fully charge your watch by exposing it to light.
(See “F. TIME REQUIRED FOR CHARGING”, for charge time reference)
