Still, two caveats. Call me old-fashioned, but I prefer the precision of a magnetic compass, particularly when using maps for route-finding, over the somewhat awkward interface of a wrist-top compass. And of course, as an electronic gadget, any wrist-top computer can break or suffer from a dead battery.
The other problem is the swimming one. These are NOT diving watches, and really aren't recommended for any prolonged submersion. That's because the barometric function requires pretty good access to the outside air. They're "waterproofed" to the extent you can get them wet from rain, stick a hand in a stream when fetching water, that sort of thing. But no swimming.
Freezing is not a problem. These watches also have thermometer functions and are good to very cold temps, although at some sub-zero point the battery may start to go dead.
Keep pointed west!
