This watch is fantastic, it has so many features that make it totally worth the bucks. Its altimeter is very accurate and the same goes for the compass, which is very easy to calibrate just simply hold it level and turn around 3 times. It is comfy and doesn't bind up or gouge your wrists. overall great watch. I don't know how well it would work in a very cold condition however, because it does have a semi large face which I can perceive could make a hassle to pull out from several layers. But as far as my testing of has gone so far its perfect.
