Signal Reception
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.
ー
While battery power is low
ー
While the watch is in the Airplane Mode,
Stopwatch Mode, Timer Mode, or Alarm
Mode
ー
When power saving is at Level 2 (GPS
signal reception also is not possible at
Level 1.)
ー
While the crown is pulled out
ー
Timer countdown operation in progress
●
If the receive operation is successful, the
time and day settings will be adjusted
automatically in accordance with the Home
City and summer time settings. Summer
time
will not be applied correctly in the cases
described below.
ー
When the summer time start date and
time, end date and time, or other rules are
changed by authorities
ー
When location information is received,
but it is not location information for your
actual location (For example, when you
are near a borderline of a city and the
acquired location information is for a
neighboring city, etc.)
●
As

summer time. If China starts to observe
summer time in the future, the time
