8. General Reference for Charging Times of
Solar-Powered Watches
The time required for recharging varies according to the model of the watch (color of the
dial, etc.). The following times are shown below only to serve as a reference.
· Recharging time refers to the amount of time the watch is continuously exposed to light.

Charging time to fully charge: Time required for recharging the watch from the stopped
state when insufficiently charged to fully charged.
Charging time for 1 day of operation: Time required for recharging the watch to run for
1 day.
Note:
Once fully charged, the watch has a continuous operating time of about six months
without further charging. When the Power Save feature has been activated, the watch
will continue to keep the correct time for about two years. However, if the watch stops
running as a result of being insufficiently charged, a considerable amount of time is
required to charge so that it starts running again as is indicated in the table. It is
therefore recommended to charge the watch at least once a month by exposing to direct
sunlight.
