You know the old saying
A slow or fast running watch is worse than a stopped (broken) watch. At least the stopped watch shows correct time twice a day!
Here is a challenge:
A person was wearing a stopped (broken) analog wrist watch with hour, minute and second hand, that also displayed the date ( Monday thru Sunday and the day of the month) which showed correct time and day at least 5 times during a continuous 15 hour period.
The person did not touch the watch settings. He was on the ground all this time.
How is this possible?
