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.
ー
While battery power is low
