16. Solar-Powered Watch Handling
Precautions
CAUTION Charging Precautions
· Charging the watch at high temperatures can cause deformation or discoloration of
external components as well as a malfunction of the components of the movement.
· Avoid charging the watch at high temperatures (about 60°C / 140°F or higher).
Examples:
· Charging by placing the watch too close to a light source that may become
hot such as an incandescent lamp or halogen lamp.
· Charging by placing the watch on an automobile dashboard that can easily
reach a high temperature.
· When charging the watch with an incandescent lamp, halogen lamp or other light
source that may reach a high temperature, always make sure to place the watch at
least 50 cm (20 in.) away from the light source to prevent the watch from reaching a
high temperature.
Charging time for 1 day of operation: Time required for charging the watch to run for 1
day with normal hand movement.
Charging time to fully charged: Time required for charging the watch from the stopped
state when insufficiently charged to fully charged
[Note]
Once fully charged, the watch has a continuous operating time of about six months
without further charging. When the Power Save function has been activated, the watch
will continue to keep time for about one year. However, if the watch stops running as a
result of being insufficiently charged, since a considerable amount of time is required to
charge so that it starts running again as is indicated in the table, try to charge the watch
everyday. It is recommended to charge the watch at least once a month by exposing to
direct sunlight.
