Just in case you're wondering, the watch definitely doesn't float! :) Had this watch for a total of 4 days before it was stripped off my wrist while wake boarding. I'm a novice boarder, was not going fast, and didn't hit the water hard when i lost it. I was actually in the water, preparing to take off and it somehow slipped off my wrist. I thought the velcro was fastened tightly enough but guess not! I Love the watch design, size, price, functionality and even the velcro strap (despite it's vulnerability to lake water), enough so that i plan to purchase another one. Unless you can see/dive to the bottom of the body of water you're in, take it off!
