2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To configure summer time and other Home City settings” to
configure your Home City and daylight saving time settings.
Important!
Proper time calibration signal reception and World Time settings depend on correct
Home City, time, and date settings in the Timekeeping Mode. Make sure you
configure these settings correctly.
3. Set the current time.
•To set the time using a time calibration signal
See “To get ready for a receive operation”.
•To set the time manually
See “Configuring Current Time and Date Settings Manually”.
The watch is now ready for use.
For details about the watch’s radio controlled timekeeping feature, see “Radio•
Controlled Atomic Timekeeping”.
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•
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•
sleep state 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.
On the dashboard of a car parked in direct sunlight•
Too close to an incandescent lamp•
Under direct sunlight•
Important!
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.
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
You can get an idea of the watch’s power level by
observing the movement of the xSecond Hand in the
Timekeeping Mode.
If the•xSecond Hand is moving normally at one-second
intervals, power is at Level 1.
If the•xSecond 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 charge.

3
xSecond Hand stopped.
z Hour Hand and cMinute Hand
stopped at 12 o’clock.
All functions disabled
When power drops to Level 3, all functions will be disabled but the watch will•
continue to keep time internally for about one week. If you recharge the battery
sufficiently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
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 overuse
of the alarm tone 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.

Supply” section of the Specifications.
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.
There actually are two sleep state levels: “second hand sleep” and “function sleep”.•

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.
The watch will not enter a sleep state while it is in the Stopwatch Mode.•
To recover from the sleep state
Move the watch to a well-lit area or press any button.
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” 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: The watch can receive the signal from the
transmitter located here:
LON, PAR, ATH Anthorn (England), Mainflingen (Germany)
HKG Shangqiu City (China)
TYO Fukushima (Japan), Fukuoka/Saga (Japan)
HNL, ANC, LAX, DEN, CHI, NYC Fort Collins, Colorado (United States)
Important!
The areas covered by•HNL and ANC are quite far from the calibration signal
transmitters, so certain conditions may cause reception problems.
When•HNL or HKG is selected as the Home City, only the time and date are
adjusted according to the time calibration signal. You need to switch manually
between standard time and daylight saving time (DST) if required.
See “To configure summer time and other Home City settings” for information about
how to do this.

Even when the watch is within range of a transmitter, signal reception may be•
impossible due to the effects of geographic contours, structures, weather, the time
of year, the time of day, radio interference, etc. The signal becomes weaker at
distances of approximately 500 kilometers, which means that the influence of the
above conditions becomes even greater.
Signal reception may not be possible at the distances noted below during certain•
times of the year or day. Radio interference may also cause problems with reception.

As of March 2010, China does not use Daylight Saving Time (DST). If China does•
go to the Daylight Saving Time system in the future, some functions of this watch
may no longer operate correctly.
Using this watch in a country covered by a time calibration signal that is different•
from the countries it supports may result in incorrect time indication due to local
application of summer time, etc.

See “Auto Receive” for details.
Manual Receive: Perform the operation under “To perform manual receive”.•
Auto Receive
With Auto Receive, the watch performs the receive operation each day•
automatically up to six times (up to five times for the Chinese calibration signal)
between the hours of midnight and 5 a.m. (according to the Timekeeping Mode
time). When any receive operation is successful, none of the other receive
operations for that day are performed.
When a calibration time is reached, the watch will perform the receive operation•
only if it is in the Timekeeping Mode or World Time Mode. The receive operation is
not performed if a calibration time is reached while you are configuring settings.
To perform manual receive
In the Timekeeping Mode, keep1. Ddepressed (for about two seconds) as the
xSecond Hand goes through the following sequence.
Moves to•YES (or Yfor some models) or NO (N) to indicate the last signal
reception result, then to READY (R).
The2. xSecond Hand indicates the operations the watch is currently performing.
When the xSecond
Hand is pointed here: It means this:
READY (R) Watch is setting up for reception.
WORK (W) Reception is in progress.
If signal reception is unstable, the•xSecond Hand
may move between WORK (W) and READY (R).
Regular timekeeping resumes after the receive operation3.
is complete.
When the receive operation is successful, the watch•
adjusts the time setting accordingly. It does not adjust
the setting if the operation failed.
Note
To interrupt a receive operation and return to the•
Timekeeping Mode, press any button.
To check the result of the latest receive operation
In the Timekeeping Mode, press D.
The•xSecond Hand will move to YES (Y) for five
seconds if the latest receive operation was successful,
or NO (N) if it was not. After that, regular timekeeping
will resume.
You can return to the Timekeeping Mode manually by•
pressing Dwhile the xSecond Hand is pointing to YES
(Y) or NO (N).
Note
The•xSecond Hand will indicate NO (N) if you have
adjusted the time or date setting manually since the
latest receive operation.
Radio-controlled Atomic Timekeeping Precautions
Strong electrostatic charge can result in the wrong time setting.•
Even if a receive operation is successful, certain conditions can cause the time•
setting to be off by up to one second.
The watch is designed to update the date automatically for the period January 1,•
2000 to December 31, 2099. Updating of the date by signal reception will no longer
be performed starting from January 1, 2100.
If you are in an area where signal reception is not possible, the watch keeps time•
with the precision noted in “Specifications”.
The receive operation is disabled under any of the following conditions.•
While power is at Level 2 or lower−
While the watch is in the power recovery mode−
When the watch is in the function sleep state (“Power Saving”)−

Checking the Current Time in a Different Time Zone
You can use the World Time Mode to view the current time in one of 29 time
zones around the globe. Each time zone has a “city code”, which is a three-letter
abbreviation of a representative city in the zone. The representative city of the time
zone that is currently selected in the World Time Mode is called the “World Time City”.
Hand Functions
x Second Hand: Indicates the currently selected World
Time City.
v Left Dial hand: Indicates the summer time setting (STD,
DST) for the currently selected World
Time City.
b Right Dial Hands: Indicate the current time in the
selected World Time City in 24-hour
format.
To view the time in another time zone
Use1. Cto rotate the vLeft Dial hand until WT is located next to the pointer ( ).
This indicates the World Time Mode.•
Use2. Dto move the xSecond Hand to the city code you want to select as the
World Time City.
The•bRight Dial Hands will move to the current time in the currently selected
World Time City. At this time, the zHour Hand and cMinute Hand will continue
to indicate the current time in the Home City.
Holding down•Dcauses the xSecond Hand to move at high speed.
For full information on city codes, see the “City Code Table” at the back of this•
manual.
If you think that the time indicated for the selected World Time City is not correct,•
it probably means that there is something wrong with your Home City settings.
Use the procedure under “To configure summer time and other Home City
settings” to correct the Home City settings.
To specify standard time or daylight saving time (DST) for a time zone
In the World Time Mode, use1. Dto select the city code
for the time whose setting you want to change.
Press2. Bto toggle the vLeft Dial hand between STD
(standard time) and DST (daylight saving time).
Note that you cannot switch between•STD (standard
time)/DST (daylight saving/summer time) while UTC is
selected as the World Time City.
Note that the•STD (standard time)/DST (daylight
saving/summer time) setting affects only the currently
selected time zone. Other time zones are not affected.
Swapping your Home City and World Time City
You can use the procedure below to swap your Home City and World Time City. This
capability can come in handy when you frequently travel between two locations in
different time zones.
The following example shows what happens when the Home City and World Time
City are swapped while the Home City originally is TYO (Tokyo) and the World Time
City is NYC (New York).
Home City World Time City
Before swapping
Tokyo
10:08 p.m.
(Standard time)
New York
9:08 a.m.
(Daylight saving time)
After swapping
New York
9:08 a.m.
(Daylight saving time)
Tokyo
10:08 p.m.
(Standard time)
To swap your Home City and World Time City
In the World Time Mode, use1. Dto select the World
Time City you want.
In this example, you would move the•xSecond Hand
to NYC in order to select New York as the World
Time City.
Wait until the•bRight Dial Hands complete their
move to the time in the currently selected World Time
City. You will not be able to perform step 2 of this
procedure until the hands stop moving.
Hold down2. Afor about three seconds until the watch
beeps.
This will make the World Time City (•NYC in this
example) your new Home City. At the same time, it
will change the Home City you had selected prior to
step 2 (TYO in this example) to your World Time City.
After swapping the Home City and World Time City,•
the watch will stay in the World Time Mode. The
xSecond Hand will point to your new World Time City
(TYO in this example).
The•bRight Dial Hands will indicate the current time
in your new World Time City.
Note
If your current World Time City supports time calibration signal reception, making it•
your Home City enables calibration signal reception for that city.

Adjusting Home Positions
Strong magnetism or impact can cause the hands and/or date of the watch to be
off, even if the watch is able to perform the signal receive operation. If this happens,
perform the applicable home position adjustment procedures in this section.
Hand home position adjustment is not required if the time and day settings are•
correct.
Note
Any time after you enter the home position adjustment mode in step 1 of the following
procedure, you can return to the Timekeeping Mode by pressing A. The watch also
will return to the Timekeeping Mode automatically if you do not perform any operation
for about two or three minutes in the home position adjustment mode. In either case,
any adjustments you made before the watch returned to the Timekeeping Mode will
be applied.
To adjust home positions
Use1. Aas shown under “Setting Modes” to enter the
“Home Position Adjustment” mode.
The watch will exit the home position adjustment mode•
automatically if you do not perform any operation for

Troubleshooting
Hand Movement and Position
 I lost track of what mode the watch is in.
Refer to “To select a mode”. To return directly to the Timekeeping Mode from any
other mode, hold down Cat least two seconds.
 The xSecond Hand is moving at two second intervals.
 All the watch’s hands are stopped at 12 o’clock and none of the buttons work.
Power may be low. Expose the watch to light until the xSecond Hand starts moving
normally, at one-second intervals.
 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.
The watch is recovering from a sleep state.•
The time setting is being adjusted following a successful auto time calibration•
signal receive operation.
The watch is returning to the Timekeeping Mode automatically from the Alarm•
Mode.
 Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode. 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 power recovers. To help power recover, leave the
watch in a location where it is exposed to light.
The current time setting is off by hours.
Your Home City setting may be wrong. Check your Home City setting and correct it,
if necessary.
 The current time setting is off by one hour.
If you are using the watch in an area where time calibration signal reception is
possible, see “To configure summer time and other Home City settings”.
If you are using the watch in an area where time calibration signal reception is
not possible, you may need to change your Home City’s STD (standard time)/
DST (daylight saving/summer time) setting manually. Use the procedure under “To
configure summer time and other Home City settings” to change the STD/DST setting.
 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.
World Time Mode
 The World Time indicated by the bRight Dial Hands in the World Time Mode is
one hour off from the actual time in the selected World Time City.
The STD (standard time)/DST (daylight saving/summer time) setting of the selected
World Time City may be wrong. Select the correct STD (standard time)/DST (daylight
saving/summer time) setting.
 The World Time indicated by the bRight Dial Hands in the World Time Mode
is off.
Your Home City settings may be wrong. Check your Home City settings and correct
them, if necessary.
Charging
 The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3. Continue exposing the watch
to light until the xSecond Hand starts moving normally (at one-second intervals).
 The xSecond Hand starts to move at one-second intervals, but then suddenly
returns to moving at two-second intervals.
The watch probably is not sufficiently charged yet. Continue keeping it exposed to
light.
Time Calibration Signal
The information in this section applies only when LON, PAR, ATH, HNL, ANC, LAX,
DEN, CHI, NYC, HKG, or TYO is selected as the Home City. You need to adjust the
current time manually when any other city is selected as the Home City.
 The xSecond Hand indicates NO (N) when I check the result of the latest
receive operation.
Possible Cause Remedy
You are wearing or moving the watch,•
or performing a button operation
during the signal receive operation.
The 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”.
The calibration signal is not being
transmitted for some reason.
Check the website of the organization that•
maintains the time calibration signal in your area
for information about its down times.
Try 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-24), which will cause the time to be adjusted automatically according to your
currently selected Home City. If this results in the wrong time setting, check your
Home City setting and correct it, if necessary.

 The current time setting is off by one hour.
Possible Cause Remedy
Signal reception on a day for switching
between STD (standard time)/DST
(daylight saving/summer time) may
have failed for some reason.
Perform the operation under “To get ready
for a receive operation”. The time setting will
be adjusted automatically as soon as signal
reception is successful.
If you are unable to receive the time calibration
signal, change the STD (standard time)/DST
(daylight saving/summer time) setting manually.
 Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy
The watch is in the Stopwatch Mode.
Auto Receive is not performed while the watch is
in the Stopwatch Mode. Hold down Cat least two
seconds to enter the Timekeeping Mode.
Your Home City setting is wrong. Check your Home City setting and correct it, if
necessary.
There is not enough power for signal
reception. Expose the watch to light to charge it.
 Signal reception is being performed successfully, but the time and/or day is
wrong.
Possible Cause Remedy
Your Home City setting is wrong. Check your Home City setting and correct it, if
necessary.
The watch may have 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 positions.
