Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.
Charging Guide
Whenever you are not
wearing the watch, leave
it in a location where it is
exposed to light.
Best charging
x
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch,
make sure that its face is
not blocked from light by the
sleeve of your clothing.
The watch may enter a
x
sleep state (page E-14) if
its face is blocked by your
sleeve even only partially.
