I know more non-divers that wear dive watches, than actual divers. Same goes for those pilot watches with the built in barometer and compass. With modern diving being almost 100% computer based, and dive profiles planned and executed as such, a dive watch does very little other than tell time these days. I do own a TAG Heuer that was given to me long before I started diving, and have never used it for diving. I remember thinking when I got that expensive watch "Maybe I should take up scuba diving now"
