When I was a ton younger I won a fancy Casio phone watch thing - was worth a heap back in the early 1990's.
Went to Rockingham beach for the day with the family. Come out of the water.. no watch. PANIC. Walked around in the water for an hour, no luck. Im upset, old mans going off.
Stand up to walk back in to go home. Something funny is under my foot. Wiggle my toes over it, and lift my foot. One Casio phone watch
Good luck dude!
