There is only one place I dive a watch. We do a River drift here (from shore) that won't get you deeper than 30' (and usually less), that you basically ride the current for a set time (0:45), and surface to swim to your exit spot (if longer, you are screwed with an exit over large stone/concrete rubble of shore scour protection. All you need is a watch...
Yeah, everything else is a computer or two, and even x2 is still way under a "luxury watch" that does nothing for you but provide "bling"....
YMMV
