Troubleshooting
Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to “Mode Reference Guide” (page E-33). To return directly to the Timekeeping
Mode, hold down C at least two seconds.
■ The x
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
(x
Second Hand stopped at 57, 58, 59, or 00).
Power may be low. Expose the watch to light until the x
Second Hand starts moving
normally, at one-second intervals (page E-17).
■ 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 (page E-20).
E-71
• The time setting is being adjusted following a successful auto time calibration
signal receive operation (page E-21).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-18). 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.
■ 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 (page E-37).
■ 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 confi gure Home City settings” (page E-37).
E-72
• 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” (page E-40) to switch from AT (AUTO) to STD (for standard time) or DST (for
summer time).
■ The time and date settings 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 indicator alignment. Adjust the
watch’s hand and day indicator home position alignment (page E-65).
E-73
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-17). Continue exposing
the watch to light until the x
Second Hand starts moving normally (at one-second
intervals).
■ The x
Second Hand starts to move at one-second intervals, but then suddenly
returns to moving at two-second intervals.
The watch probably is not suffi ciently charged yet. Continue keeping it exposed to
light.
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.
E-74
■ The x Second Hand indicates NO (N) when I check the result of the latest
receive operation.
Possible Cause Remedy Page
• You are wearing or moving the watch,
or performing a button operation
during time calibration 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 time
calibration signal receive operation is
being performed.
E-26
You are in an area where signal reception
is not possible for some reason.
See “Approximate Reception Ranges”. E-23
The alarm time was reached during time
calibration signal reception.
The alarm sounded during time
calibration signal reception, causing
reception to be canceled.
—
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.

E-75
■ The current time setting changes after I set it manually.
You may have the watch confi gured for Auto Receive of the time calibration signal
(page E-28), 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-37).
■ 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 AT (AUTO)
to STD (for standard time) or DST (for
summer time).

■ Signal reception is being performed successfully, but the time and/or day is
wrong.
Possible Cause Remedy Page
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 indicator alignment.
Adjust the watch’s hand and day
indicator home positions.

World Time
■ The indicated World Time is wrong.
There is a problem with your Home City settings.
Check your Home City settings.
See “To confi gure Home City settings” (page E-37).
■ The indicated World Time is one hour off.
The daylight saving time (summer time) setting for the World Time city is wrong.
See “To view the time in another time zone” (page E-50).
Alarm
■ The alarm does not sound.
• Power may be low. Expose the watch to light until the x
Second Hand starts moving
normally, at one-second intervals (page E-17).
• The time setting is wrong in terms of a.m. and p.m.
• The crown may be pulled out. Push the crown back in.
