I love the looks of this watch but there are many watches that look similar for about $50 or less. The price of this watch seemed worth it for the sensors, I am a beginner skier and thought it would be fun to see what altitudes I was at on different slopes.  I did everything the user guide said to calibrate the sensors but none of them worked.  The compass was okay.  The thermometer was always high, which was expected due to body heat, but it was never even consistent.  The altimeter was even worse, and that was the primary reason I bought the watch.  Even at known, posted altitudes, the watch could be off from hundreds to over a thousand feet, and again, was nowhere near consistant.  Had it been consistently off, it would have been easy to calculate the approximate altitude, but it was pretty much worthless for that purpose.  The watch did hold up to extreme cold and snowy conditions, but if you buy this watch, you're going to pay a lot for a watch that looks like it has a bunch of cool features.
