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
- As of July 2017, 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.
