■ Signal reception is being performed successfully, but the time and/or day is wrong.
Possible Cause Remedy Page
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. E-67
Alarm
■ The alarm does not sound.
Possible Cause Remedy Page
Battery power is low.
Expose the watch to light until battery power is
back to normal.

■ Nothing happens when I rotate the crown.
Possible Cause Remedy Page
The crown has been left pulled out for more than
two minutes (30 minutes in the case of hand home
position adjustment) without any operation being
performed.
Push the crown back in and then pull it out again to
restore normal operation.

x You are wearing or moving the watch, or
performing a button operation during the signal
receive operation.
x 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.

An alarm sounded while time signal reception was
in progress.
Try again later. —
You are in an area where signal reception is not
possible for some reason.
See “Appropriate Signal Reception Location (GPS
Signal)”, “Approximate Reception Ranges” and
“Appropriate Signal Reception Location (Time
Calibration Signal)”.

The watch may be in the Airplane Mode. Exit the Airplane Mode. E-45
Current conditions do not allow signal reception. Eliminate the problem and try again. E-41

■ I think my Home City (time zone) setting is correct and signal reception is successful, but the
time and/or date is wrong.
Possible Cause Remedy Page
Time and/or date settings cannot be adjusted
automatically for some reason.
Adjust time and date settings manually. E-63
Time Information (Time Calibration)
The time calibration signal information in this section applies only when LONDON (LON), PARIS (PAR),
ATHENS (ATH), LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC), HONG
KONG (HKG), or TOKYO (TYO) is selected as the city.
■ The

Second Hand indicates N (NO) when I check the result of the latest receive operation.
Possible Cause Remedy Page
The time calibration signal is not being transmitted
for some reason.
x For details about each time calibration signal,
check the website of the organization that
maintains it.
x Try again later.
—
■ The watch cannot receive the time calibration signal.
Possible Cause Remedy Page
Your Home City (time zone) setting may be wrong.
x Perform a GPS position information receive
operation.
x Or confi gure your Home City (time zone) setting
so it is correct.

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-24). Continue
exposing the watch to light until the
1
1
Second Hand starts moving normally (at one-second intervals).
This could indicate that over-discharge has occurred and so the secondary battery can no longer be
recharged. If this happens, contact your retailer to have the secondary battery replaced.
■ The 1
1
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 Information (GPS)
■ The
1
1
Second Hand indicates N (NO) when I check the result of the latest receive operation.
Possible Cause Remedy Page
The watch continues the signal receive operation
for a long time.
(The
1
1
Second Hand remains at T+P or T (TIME).)
x The watch may be receiving a leap second.

Information”, “GPS Signal Auto Receive”,
“Receiving GPS Time Information”, and “Leap

■ 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.
x The watch is recovering from a sleep state (page E-27).
x The time setting is being adjusted following a successful auto signal receive operation (page E-28).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-25). 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.
x Your Home City (Time Zone) setting may be wrong. Check your Home City (Time Zone) setting and
correct it, if necessary (page E-48).
■ The current time setting is off by one hour, 30 minutes, or some regular interval.
x The summer time setting is not correct.
x Correct the summer time setting (pages E-60 and E-61).
■ 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-67).
