Movement of a hand seems strange
Time/calendar becomes incorrect soon after manual adjustment.
The reference position of the hands and indication on the watch may be incorrect.
If the reference position of the hands and indication is not correct, the time and calendar are not indicated correctly even if the time info is received.
Check the reference position referring to "Checking and correcting the reference position" and correct it if needed.
