Solutions
Do not move the watch while it is receiving a radio signal.
Because it takes time to receive a radio signal successfully,
leave the watch untouched for 12 minutes at the longest.
Place the watch where it is able to easily receive a radio signal.
Transmitting stations may have stopped transmitting radio
signals for some reason (Transmission stop).
Check the website of each transmitting station for further
information concerning a transmission stop. Attempt to
receive a radio signal again after a while.
Reselect the time zone able to receive the radio signal.
The time required for charging the watch depends entirely
on the amount of exposed light the watch receives.
Refer to "Standard charging time" to charge the watch.
The built-in IC of the watch has fallen into an unstable
condition.
Refer to "In case of an abnormal movement" to reset the
built-in IC.
