7 Charging the battery
This 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 at least once a month.
• After taking off the watch, put it where the dial is exposed to bright light,
such as by a window.
• Before storing the watch in a dark place for an extended period of time, fully
charge the battery.
When the watch is covered with long sleeves, for example, the battery may not
be charged sufficiently. Try to keep the watch exposed to light.
Do not charge the battery at a high temperature (about 60˚C/140˚F or
higher).
