Troubleshooting

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?

The watch cannot receive time calibration signals while auto adjustment is disabled or while the watch is in a mode other than the Timekeeping Mode. Return to the Timekeeping Mode.

Is your Home City setting correct for your location?

The watch will not indicate the correct time if the Home City setting is wrong. Change your Home City setting so it correctly reflects your location.

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
  • Timer countdown operation in progress

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.

Q3Signal reception should have been successful, but the watch’s time and/or day is wrong.

Is the time zone where you are using the watch specified correctly?

Is the hand and/or day indicator alignment correct?
