■ Signal reception is being performed successfully, but the time is wrong.
Possible Cause Remedy Page
Your location setting is wrong.
Check your location setting and correct it, if
necessary.
E-22
The watch may have been exposed to magnetism
or strong impact, which has caused problems with
proper hand alignment.
Adjust the watch’s hand home positions. E-29
E-34
■ The
x
Second Hand indicates N (NO) when I check the result of the latest receive operation.
Possible Cause Remedy Page
You are wearing or moving the watch, or
x
performing a button operation during the signal
receive operation.
The watch is in an area with poor reception x
conditions.
Keep the watch in an area where reception
conditions are good while the signal receive
operation is being performed.
E-18
You are in an area where signal reception is not
possible for some reason.
See “Approximate Reception Ranges”. E-17
The calibration signal is not being transmitted for
some reason.
Check the website of the organization that x
maintains the time calibration signal in your area
for information about its down times.
Try again later. x

■ 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-19), which will
cause the time to be adjusted automatically according to your currently selected location. If this results in
the wrong time setting, check your location setting and correct it, if necessary (page E-22).
■ Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy Page
Your location setting is wrong.
Check your location setting and correct it, if
necessary.
E-22
There is not enough power for signal reception. Expose the watch to light to charge it. E-10
E-33
Hand movement is stopped.■
The watch may have been exposed to magnetism, which will cause the hands to stop at their current
positions. Pull the crown out to the fi rst click or press a button to restart hand movement. If the indicated
time is not correct, perform home position adjustment. See “Adjusting Home Positions Manually” (page
E-29).
■ The current time setting is off by hours.
Your location setting may be wrong. Check your location setting and correct it, if necessary (page E-22).
■ 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 battery charge level drops to Level 4 (page E-11). Continue exposing the watch
to light until the
x
Second Hand starts moving normally (at one-second intervals).
Time Calibration Signal
The information in this section applies only when CN (HKG, HONG KONG), or JP (TYO, TOKYO) is
selected as the current location.

Troubleshooting
Hand Movement and Position
■ The
x
Second Hand is moving in the pattern: 1 second 1 second 2 seconds.
The battery charge is starting to go low. Expose the watch to light to charge it. See “Charging the Watch”
(page E-10).
■ The
x
Second Hand is moving at two-second intervals.
■ All of the watch’s hands are stopped at 12 o’clock, and the A button and crown do not
do
anything
.
The battery charge may be low. Expose the watch to light until the
x
Second Hand starts moving
normally, at one-second intervals (page E-11).
■ 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-15).
x
The time setting is being adjusted following a successful auto time calibration signal receive operation x
(page E-16).
Nothing happens when I rotate the crown.■
Leaving the crown pulled out for more than two minutes without performing any operation will
automatically cause the setting operation to become disabled. If this happens, press the crown back in
and then pull it out again to confi gure settings. See “Crown Operations” (page E-4).
