A Eco-drive watch or any other
solar powered watch has a battery which is charged by exposing the dial
to light such as direct sunlight or fluorescent lamps.
To obtain the best performance:
- Expose the dial to direct sunlight as least once a month.
- After taking off the watch from wrist, put it where the dial is exposed to bright light such as by a window.
- Before storing the watch in dark place for an extended period of time, fully charge the battery.
When the watch is covered with long sleeves, for example, the battery
many not be charged sufficiently. Try to keep the watch exposed to
light.
Cautions about charging:
- Excessively high temperature at charging battery may cause
discoloration and deformation of the exterior, eg. leather strap, and
malfunction of the movement.
- Do not charge the battery at a high temperature (about 60oC /140F or higher)
- Do not charge the battery by light such as an incandescent lamp or halogen lamp
- Charging the battery where the temperature becomes extremely high – such as on the dashboard.
Although your watch has battery duration
of about 6 to 12 months or more after fully charged and does not
require further charging, it is advisable to expose the dial direct
sunlight as least once a month if the watch is kept in the dark place,
in order to keep the solar / eco-drive function in good condition and
its best performance in the future.
However, if the watch was not exposed to
light source for a few months and was kept in the dark place, the
battery may malfunction eventually; a battery replacement may be
required.
