The actual level at which some functions are disabled depends on the watch model.
Frequent display illumination can run down the battery quickly and require
charging. The following guidelines give an idea of the charging time required to
recover from a single illumination operation.
− Approximately 5 minutes exposure to bright sunlight coming in through a window
− Approximately about 8 hours exposure to indoor fl uorescent lighting
Be sure to read "Power Supply" (page E-55) for important information you
need to know when exposing the watch to bright light.

Operation Guide 5173
The electricity generated by the solar cell of the watch is
stored by a built-in battery. Leaving or using the watch
where it is not exposed to light causes the battery to run
down. Make sure the watch is exposed to light as much
as possible.
When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
You should try to keep the watch outside of your sleeve
as much as possible. Charging is reduced signifi cantly
if the face is even only partially covered.
Battery discharges in the dark.
