I was looking for a basic altimeter to take hiking and skiing. Found this one on sale and thought I'd try it out. Good stuff for the money. I dig the 'Ski' mode which tracks your accumulated vertical feet. It seems accurate enough for my use (7000' - 13,000'). Like other altimeters, you have to calibrate it often, but it's an easy thing to do. Only problem: the watch case came detached after about a year of not-too-hard use, but they have a 2-year warranty, and they happily replaced it with a new(er) watch that seems to have a beefier case. Oh...and the thermometer is pretty much useless unless you take it off your wrist and let it sit around for a little while (but hey...it is on your wrist...what would you expect?) Good watch.
Pros: Altimeter seems pretty accurate, large face is easy to read, ski chrono is pretty cool, excellent company service, buttons easy to reach.
Cons: Buttons a bit TOO easy to reach (often get bumped), poor case design (that may have been re-designed?), thermometer - as in other watches - is pretty much just a gadget.
