Time Adjustment Using a
Time Signal

Overview

The watch's time and day settings can be
configured in accordance with a received time
calibration signal.
Important!
In order to make it possible for the
●
current time setting to be adjusted
correctly based on time calibration
signal reception, you need to specify
the time zone where you are using the
watch.
However, if the watch was unable to
●
connect with a phone even once for
time adjustment during the previous
day while connection with a phone is
being used, it will automatically try to
receive a time calibration signal.
Disable auto time adjustment
●
whenever you are inside an aircraft or
in any other area where radio wave
reception is prohibited or restricted.
