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-10) 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

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-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: The watch can receive the signal from the transmitter
located here:

STD/DST Switching
You can select summer time or standard time independently for each city. The initial default setting for all
cities is AUTO.
Normally you should use the 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 your Home City.
*Coordinated Universal Time, the world-wide scientific standard of timekeeping. The reference point for
UTC is Greenwich, England.

−While the watch is changing dates at midnight
xOnce started, stopwatch timing continues until you press Ato stop it, even if you exit the Stopwatch
Mode to another mode and even if timing reaches the stopwatch limit defined above.
xYou can press Ato start an elapsed time operation immediately after entering the Stopwatch Mode,
even if the watch’s hands are still moving to their initial Stopwatch Mode positions. Note, however, that
if the stopwatch was not reset after the last elapsed time operation, timing will restart from where it was
last stopped, and not from 12 o’clock.
xThe
2
Second Hand indicates the 0.1-second count for the first 30 seconds of a stopwatch elapsed
time operation. After that, the hand stops at 12 o’clock, but 0.1-second timing continues internally after
the first 30 seconds. The
2
Second Hand will jump to the current value whenever A(Stop) is pressed.

■The current time setting is off by one hour.
Possible Cause Remedy Page
The 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 Home City.
Use the procedure under “To switch between
standard time and summer time manually” to switch
from AUTO to STD (for standard time) or DST (for
summer time).
E-22
■Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy Page
The watch is in the Stopwatch Mode.
Auto Receive is not performed while the watch is
in the Stopwatch Mode. Hold down Bat least two
seconds to enter the Timekeeping Mode.

Time Calibration Signal
The information in this section applies only when LONDON (LON), PARIS (PAR), ATHENS (ATH),
HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI),
NEW YORK (NYC), HONG KONG (HKG), or TOKYO (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
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
receive operation.
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.
E-13
You are in an area where signal reception is not
possible for some reason. See “Approximate Reception Ranges”. E-12
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-14), 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 (page E-20).
E-33
■The current time setting is off by hours.
xYour Home City setting may be wrong. Check your Home City setting and correct it, if necessary (page
E-20).
■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
configure Home City settings” (page E-20).
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 Home City. Use the procedure under “To switch
between standard time and summer time manually” (page E-22) to switch from 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-29).
Charging
■The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-8). Continue exposing the watch to light until
the
2
Second Hand starts moving normally (at one-second intervals).
■The
2
Second 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.
E-32
Troubleshooting
Hand Movement and Position
■I lost track of what mode the watch is in.
Refer to “Mode Reference Guide” (page E-18). To return directly to the Timekeeping Mode, hold down Bat
least two seconds.
■The
2
Second 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
2
Second Hand starts moving normally, at one-
second intervals (page E-8).
■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-10).
xThe time setting is being adjusted following a successful auto time calibration signal receive operation
(page E-11).
■Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-9). 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.
