The face of the watch is a solar panel 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, be sure
to leave it in a location where
it is exposed to light.
x
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch, makes
sure that its face is not blocked
from light by the sleeve of your
clothing.

state (page E-12) if its face is
blocked by your sleeve even
only partially.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot. Take care when
handling the watch to avoid burn injury. The watch can become particularly hot when exposed to
the following conditions for long periods.

You can get an idea of the watch’s power level by observing the movement of
the
Second Hand .
x
Second Hand is moving normally at one-second intervals, power is
at Level 1.
x
Second Hand is moving at two-second intervals, power is at Level 2,
which is quite low (Low battery alert ). Expose the watch to light as soon as
possible so it can charge.

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever
power suddenly drops below a certain level due to continuous signal reception or other operations over a
short period. Note that all operations are disabled while the watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal operation after power
recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power
to recover sooner.

This section explains how the watch updates its time settings when the city setting is a city in Japan,
North America, Europe, or China, and is one that supports time calibration signal reception.
