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
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
xBest 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.
xThe watch may enter a sleep
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.
xOn the dashboard of a car parked in direct sunlight
xToo close to an incandescent lamp
xUnder direct sunlight
E-10
Important!
xKeep 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.
xStoring 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
You can get an idea of the watch’s power level by observing the movement of
the
2
Second Hand.
xIf the
2
Second Hand is moving normally at one-second intervals, power is
at Level 1.
xIf the
2
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.
Level Hand Movement Function Status
1 Normal. All functions enabled
22
2
Second Hand moves at
two-second intervals.
Time calibration signal reception and
home position adjustment disabled
3 All hands stopped at 12 o’clock. All functions disabled
xWhen power drops to Level 3, all settings (including timekeeping) will be
cleared. Recharging the battery will reset all settings to their initial factory
defaults, so you will need to configure settings again.


Moves at two-second
intervals.
E-11
xWhen the watch is at Level 3, exposing it to light for a while will cause the
2
Second Hand to move to
the position of second 57. This indicates that charging has started.
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.

xThe above times are for reference only. Actual times depend on lighting conditions.
xFor details about the operating time and daily operating conditions, see the “Power Supply” section of
the Specifications (page E-49).
E-12
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.
xThere actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark Operation
60 to 70 minutes (second hand sleep) Only the 2
2
Second Hand will stop at its current position.
6 or 7 days (function sleep) xAll hands stopped at 12 o’clock.
xOnly day indication operates normally.
xThe 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.
xThe watch will not enter a sleep state while it is in the Stopwatch Mode, or while an elapsed time
operation is in progress in the Timekeeping Mode or the World Time Mode.
To recover from the sleep state
Move the watch to a well-lit area, perform a crown operation, or press any button.
E-13
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 “Configuring Current Time and Date Settings Manually” (page E-32) for more
information.
xTime calibration signal reception is enabled while the watch is in the Timekeeping Mode or World Time
Mode. In this manual, all examples show time calibration signal reception in the Timekeeping Mode.
The same procedures apply while the watch is in the World Time Mode.
xTime calibration reception is based on the applicable mode’s city setting. In the Timekeeping Mode,
the city setting is the Home City. In the World Time Mode, it is the World Time City (page E-28).
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.
If the city setting is this: The watch can receive the signal from the transmitter
located here:
LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainflingen (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)
Fort Collins, Colorado (United States)
Important!
xThe areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.

Selecting a City
Your watch lets you select from among city codes for 29 cities around the globe, plus one code for
UTC (Universal Coordinated Time). Selecting a city code causes the watch’s time setting to change
automatically to indicate the current time in that zone.
Important!
xYou can use the same steps to select a city code in the Timekeeping mode and the World Time Mode.
xIn the Timekeeping Mode, the city setting is the Home City, and in the World Time Mode, it is the World
Time City.
To select a city
Note
xThis watch does not have a city code that corresponds to
Newfoundland.
1. Pull out the crown to the second click.
xThis will cause the
2
Second Hand to move to the city code of
the currently selected city.
xThis indicates the city code setting mode.
xLeaving the crown pulled out for more than two minutes without
performing any operation will automatically cause crown
operations to become disabled. If this happens, press the
crown back in, pull it out, and then start the operation over
again.
xFor details about city codes, see the “City Code Table” at the

STD/DST Switching
You can select summer time or standard time independently for each city. The initial default setting for all
cities is AT (AUTO).
Normally you should use the AT (AUTO) setting because it automatically switches between summer time
and standard time. You should change the setting to STD (standard time) or DST (summer time) in the
following cases.
−When using the watch in a city not included in the City Code Table
−When the switching dates in your location are different from those shown in the City Code Table
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time.
Remember that not all countries or even local areas use Daylight Saving Time.
xNote that you cannot switch between STD (standard time) and DST (daylight saving time) while UTC*
is selected as the city code.
*Coordinated Universal Time, the world-wide scientific standard of timekeeping. The reference point for
UTC is Greenwich, England.

Troubleshooting
Hand Movement and Position
■I lost track of what mode the watch is in.
Refer to “Mode Reference Guide” (page E-22). To return directly to the Timekeeping Mode, pull out the crown
to the first click hold down Bfor at least two seconds. To return to the Timekeeping Mode, push the
crown back in.
■The
2
Second Hand is moving at two-second intervals.
Power may be low. Expose the watch to light until the
2
Second Hand starts moving normally, at one-
second intervals (page E-10).
■The hands of the watch suddenly start moving at high speed, even when I do not perform any
operation.
This could be due to any one of the following causes. In all cases, the hand movement does not indicate
malfunction, and should stop shortly.
xThe watch is recovering from a sleep state (page E-12).
xThe time setting is being adjusted following a successful auto time calibration signal receive operation
(page E-13).
■Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-11). Do not perform any operation until the hands
return to their normal positions (in about 15 minutes). The hands should return to their correct positions when
normal operation returns. To help power recover, leave the watch in a location where it is exposed to light.
■All hands are at 12 o’clock and nothing happens when I press any button.
The rechargeable battery is dead. Expose the watch to light to charge the battery and restore normal
operation.
E-45
■The current time setting is off by hours.
xYour city setting may be wrong. Check your city setting and correct it, if necessary (page E-28).
■The current time setting is off by one hour.
xIf you are using the watch in an area where time calibration signal reception is possible, see “To select
a city” (page E-28).
xThe period when summer time is applied in the location where you are using the watch may be
different from the period set for your currently selected city. Use the procedure under “To switch
between standard time and summer time manually” (page E-31) to switch from AT (AUTO) to STD (for
standard time) or DST (for summer time).
■The hands and/or day indications are off.
This could indicate that the watch has been exposed to magnetism or strong impact, which has caused
problems with proper hand and day alignment. Adjust the watch’s hand and day home position alignment
(page E-39).
■Data indication is correct, but it is not in the middle of the day indicator.
The date is in the process of changing. For information about how the date changes, see page E-2.
Charging
■The watch does not resume operation after I expose it to light.
It can take quite a long time to charge the battery after the power level drops to Level 3 (page E-10). Continue
exposing the watch to light until the
2
Second Hand starts moving normally (at one-second intervals).

the current time manually when any other city is selected.
■The
2
Second Hand indicates N (NO) when I check the result of the latest receive operation.
Possible Cause Remedy Page
xYou are wearing or moving the watch, or
performing a button operation during the signal

xThe watch is in an area with poor reception
conditions.
Keep the watch in an area where reception
conditions are good while the signal receive
operation is being performed.

You are in an area where signal reception is not
possible for some reason. See “Approximate Reception Ranges”. E-14
The calibration signal is not being transmitted for
some reason.
xCheck the website of the organization that
maintains the time calibration signal in your area
for information about its down times.
xTry again later.

■The current time setting changes after I set it manually.
You may have the watch configured for Auto Receive of the time calibration signal (page E-17), which will
cause the time to be adjusted automatically according to your currently selected city. If this results in the
wrong time setting, check your city setting and correct it, if necessary (page E-28).
E-47
■Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy Page
Your city setting is wrong. Check your city setting and correct it, if necessary. E-13
