The watch continues to operate, even when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will result in some watch
functions to be disabled. If the battery goes dead, you will have to re-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.

single illumination operation.
Approximately 5 minutes exposure to bright sunlight coming in through a window
Approximately about 8 hours exposure to indoor fluorescent lighting

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 significantly if
the face is even only partially covered.
