Troubleshooting
Signal Reception (GPS)
Q1The watch cannot perform a receive operation.
Is the watch’s battery charged?
Signal reception is not possible while battery power is low. Keep the watch exposed to light until it recharges sufficiently.
Is the watch in the Timekeeping Mode (not Airplane Mode)?
Signal reception is possible only while the watch is in the Timekeeping Mode (not Airplane Mode).
After checking the above, the watch still cannot perform a receive operation.
GPS signal reception is not possible under the conditions described below.
- During power saving
- While the crown is pulled out
- While the watch temperature is less than approximately -10°C (14°F) or more than approximately 60°C (140°F)
Q2The second hand remains at “T+P” or “T(TIME)” during the signal receive operation.
The watch may be receiving leap second information.
Q3The signal receive operation always fails.
Is the watch in a location that is appropriate for signal reception?
Check your surroundings and move the watch to a location where signal reception is better.
Is the face of the watch pointed straight upwards at the sky?
Minimize movement of the watch while the receive operation is in progress.
When the watch is set up for auto receive, take care to avoid covering the watch face with the sleeve of your clothing.
An alarm started sounding while the receive operation was in progress.
Receive stops if an alarm operation starts while it is being performed. Disable the alarm.
Q4Signal reception should have been successful, but the watch’s time and/or day is wrong.
Is your Home City (time zone) setting correct for your location?
Change your Home City (time zone) setting so it correctly indicates your location.
Acquiring GPS Position Information Manually Selecting a Time Zone
After checking the above, the time and/or day settings is still wrong.
Adjust time and day settings manually.
Signal Reception (Time Calibration Signal)
Q1The watch cannot perform a receive operation.
Is the watch’s battery charged?
Signal reception is not possible while battery power is low. Keep the watch exposed to light until it recharges sufficiently.
Is the watch in the Timekeeping Mode (not Airplane Mode)?
Signal reception is possible only while the watch is in the Timekeeping Mode (not Airplane Mode).
Is your Home City (time zone) setting correct for your location?
The watch will not indicate the correct time if the Home City (time zone) setting is wrong. Change your Home City (time zone) setting so it correctly indicates your location.
Acquiring GPS Position Information Manually Selecting a Time Zone
After checking the above, the watch still cannot perform a receive operation.
Time calibration signal reception is not possible under the conditions described below.
- When watch is at Level 2 power saving
- When the crown is pulled out
- While the watch temperature is less than approximately -10°C (14°F) or more than approximately 60°C (140°F)
If successful reception is not possible for some reason, you can adjust the time and day settings manually.
Q2The signal receive operation always fails.
Is the watch in a location that is appropriate for signal reception?
Check your surroundings and move the watch to a location where signal reception is better.
Did you avoid touching the watch while the receive operation was in progress?
Minimize movement of the watch and do not perform any watch operation while a receive operation is in progress.
Is there an alarm configured to sound during the same period that the signal receive operation is performed?
Receive stops if an alarm operation starts while it is being performed. Disable the alarm.
Is the signal transmitter in your area transmitting a signal?
The transmitter of the time calibration may not be transmitting a signal.
Try again later.
Alarms
Q1The alarm does not sound.
Is the watch’s battery charged?
Keep the watch exposed to light until it recharges sufficiently.
The crown is pulled out.
The alarm will not sound while the crown is pulled out. Push the crown back in to its normal position.
Hand Movement and Indications
Q1I don’t know what mode the watch is in.
Hold down (C) for at least two seconds to return to the Timekeeping Mode.
- Take care not to hold down (C) too long. Holding down (C) for about four seconds will enter or exit the Airplane Mode.
Q2The second hand is jumping at two-second or five-second intervals.
Battery power is low. Keep the watch exposed to light until it recharges sufficiently.
Q3All hands are stopped and buttons do not work.
The battery is dead. Keep the watch exposed to light until it recharges sufficiently.
Q4The hands suddenly start moving at high speed.
This is due to one of the reasons below, and does not indicate malfunction. Simply wait until normal hand movement resumes.
- The watch is recovering from a power saving state. Power Saving Function
- The hands are moving to their new positions following a GPS signal or time calibration signal receive operation. Time Adjustment (GPS, Time Calibration Signal)
Q5Hands are stopped and buttons do not work.
The watch is in the charge recovery mode. Wait until the recovery process is complete (for about 15 minutes). The watch will recover more quickly if you place it in a brightly lit location.
Q6The current time displayed by the watch is off by a few hours.
The city (time zone) setting is not correct. Select the correct setting.
Q7The current time indicated by the watch is off by one hour or 30 minutes.
The summer time setting is not correct. Select the correct setting.
Q8Hands and/or the day indicator is out of alignment.
Strong magnetism or impact may cause the hands of the watch to go out of alignment. Correct hand position alignment.
Crown Operations
Q1Nothing happens when I rotate the crown.
If you do not perform any operation for about two minutes after pulling out the crown (approximately 30 minutes in the case of hand and day indicator alignment operations), crown operations will automatically become disabled. Push the crown back in to its normal position and then pull it out again.
