Well done chris!!!!
Just a note.... is the watch meant to be water resistant or pressurised? If so you may need to take it to a watch maker to have him check it.
Good on you for finding the diamond!
Reminds me of a joke.... teenager of contact lenses so that he could play sport without glasses. He lost one one day playing basketball in the driveway and came to tell his mother... she sent him back out to search the driveway for the lost contact lense. After half an hour on his hands and knees he came back in to tell her he just couldnt find it. She walks outside and starts scanning the driveway... minutes later she finds the lost contact lense and holds it aloft.
HOW did you find that so easily? asks the teenager....
Easy!, says his mother... You were looking for a contact... I was looking for $500.
Just keep swimming... just keep swimming.. just keep swimming....
