Precautions
When the watch is unable to adjust its time
●
in accordance with a calibration signal for
some reason, average timekeeping
accuracy is within ±15 seconds per month.
Note that an internal decoding process the
●
watch performs after it receives a signal may
cause the time setting to be slightly off (by
less than one second).
GPS signal and time calibration signal
●
reception will not be possible under any of
the watch conditions described below.
While battery power is low
ー
While the watch is in the Airplane Mode,
ー
Stopwatch Mode, Timer Mode, or Alarm
Mode
When power saving is at Level 2 (GPS

City and summer time settings. Summer
time will not be applied correctly in the cases
described below.
When the summer time start date and
ー
time, end date and time, or other rules are

actual location (For example, when you
are near a borderline of a city and the
acquired location information is for a
neighboring city, etc.)

summer time. If China starts to observe
summer time in the future, the time
displayed by the watch for China may not be
correct.
