Charging the Watch
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
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.
x On the dashboard of a car parked in direct sunlight
x Too close to an incandescent lamp
x Under direct sunlight
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
x Best charging
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.
x The watch may enter a sleep
state (page E-10) if its face is
blocked by your sleeve even
only partially.

Important!
x Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps
to ensure that power does not run down.
x Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to
bright light whenever possible.
Power Levels

Moves at two-second
intervals.
x When power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the
battery will reset all settings to their initial factory defaults.
E-8
Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area
where it is dark. The table below shows how watch functions are affected by Power Saving.
x There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark Operation
60 to 70 minutes (second hand sleep)
6 or 7 days (function sleep)
x The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
To recover from the sleep state
Move the watch to a well-lit area or press any button.
You can get an idea of the watch’s power level by observing the movement of
31
the
Second Hand.
x If the 2 Second Hand is moving normally at one-second intervals, power is
at Level 1.
x If the 2 Second Hand is moving at two-second intervals, power is at Level 2,
which is quite low. Expose the watch to light as soon as possible so it can

Power Recovery Mode
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.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See “Confi guring Current Time and Date Settings Manually” (page E-23) for more
information.
This section explains how the watch updates its time settings when the city code selected as the Home
City is in Japan, North America, Europe, or China, and is one that supports time calibration signal
reception.
If your Home City Code setting is this:
LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainfl ingen (Germany)
HONG KONG (HKG) Shangqiu City (China)
TOKYO (TYO) Fukushima (Japan), Fukuoka/Saga (Japan)
NEW YORK (NYC), CHICAGO (CHI),
DENVER (DEN), LOS ANGELES (LAX),
ANCHORAGE (ANC), HONOLULU (HNL)
Important!
x The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
The watch can receive the signal from the transmitter
located here:
Fort Collins, Colorado (United States)
