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).
Time calibration signal reception is not
possible under the conditions described
below.
While battery power is low
While the watch is in the Stopwatch Mode,
Timer Mode, or Alarm Mode
At Power Saving Level 2
While the crown is pulled out
While a timer countdown operation is in
progress
While the Home City setting is a time zone
where time signal reception is not
possible
While the watch is outside the time signal
reception range
When the receive operation is successful,
the time and/or day settings will be adjusted
automatically. Summer time will not be
applied correctly in the case described
below.
When the summer time start date and
time, end date and time, or other rules are
changed by authorities
If your watch is connected with a phone,
settings must be configured so G-SHOCK
Connected can acquire location
information. Even if you are in an area that
is within the reception range of a time signal,
reception will not be performed if settings
are configured in a way that makes signal
reception impossible.
As of July 2018, China does not observe
summer time. If China starts to observe
summer time in the future, the time
displayed by the watch for China may not be
correct.
Using Watch Operations to
Adjust the Time Setting
Selecting Your Home City’s Time
Zone
Use the procedure in this section to select the
time zone of the city you want to use as your
Home City.
Important!
If you do not specify the time zone
where you are using the watch, the
current time setting will not be correct
after it is adjusted based on a time
calibration signal.
1. Loosen the crown and then pull it out to the
second click.
The second hand indicates the currently
selected time zone, while the mode hand
indicates the current summer time setting.
The time zone is indicated as a time
offset. ±0 hours is indicated when the
second hand is at 12 o’clock, with other
offsets indicated when it is to the left and
right of 12 o’clock. For information about
time zone positions, go to the section

pointed at A (a.m.) or P (p.m.), set the
