Even when the watch is in the display sleep state, analog time timekeeping and auto signal receive are both performed.
•The watch does not enter the display sleep state if it is in the Timer Mode or Stopwatch Mode.
•Function sleep state
The function sleep state is triggered whenever the watch is left in the dark for six or seven days.
•Alarms and the Hourly Time Signal are also disabled while the watch is in the function sleep state.
Analog time timekeeping and auto signal receive are not performed while the watch is in the function sleep state.
