If your looking for a watch for the office and outdoors that can last a lifetime, this is it. This watch looks and feels GREAT, and it has everything you need to keep you busy. The HR monitor is very accurate. Slope reading, barometer, altimeter, seem to be as well. The temp gauge is very accurate too when off of your wrist and away from your body heat. Packed with cool features and style, this watch has it all. I thought the backlight, although unique, is weakly lit and should be brighter. I have also slept right through the 30 sec alarm (auto shut-off) a few times.
