Auto Time Calibration Signal
Receive
An automatic time calibration signal receive
operation is performed and the time and day
settings are adjusted between midnight and
5:00 a.m. Once a signal receive operation is
successful, no more auto receive operations
are performed that day.
Getting Ready
Enter the World Time Mode or the Stopwatch
Mode with the stopwatch reset to all zeros.

Measuring Elapsed Time
l
Place the watch near a window or some other
location appropriate for signal reception.
The second hand points to [R] while the
●
receive operation in progress.
When the receive operation is successful,
●
the time and day settings will be adjusted
automatically.
Note
Reception takes anywhere from about
●
two minutes to about 10 minutes. It can
take as long as 20 minutes.
If the watch connects with a phone and
●
adjusts its time setting, the watch will
not perform auto receive of a time
calibration signal for the rest of that day
or the next day.
Manual Time Signal Receive
1.
Place the watch near a window or some
other location appropriate for time signal
reception.

Note
The receive operation takes anywhere
●
from about two minutes to about 10
minutes. It can take as long as 20
minutes.
Time calibration signal reception is
●
better at night than during the day.
A time calibration signal operation
●
cannot be received while the watch is
paired with a phone.
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
ー
While an elapsed time operation is in
ー
progress (Auto Receive only disabled.)
At Power Saving Level 2
ー
While the crown is pulled out
ー
While the Home City setting is a time zone
ー
where time signal reception is not
possible
While the watch is outside the time signal
ー
reception range
While the watch is paired with a phone
ー
To perform a manual time calibration signal
●
receive operation, make sure the watch is
not paired with a phone. If it is, delete the
watch's pairing information before
performing the manual receive operation.
Unpairing
l
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
ー
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 OCEANUS
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 January 2019, 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.
