This wrist-top computer has more features than you can shake a stick at. The ski chronograph works with the altimeter, after you input the base and current altitude, press start and the chrono graph stops when you reach the base altitude and calculates the speed of the descent. There is also a barometer that displays both sea level and absolute pressure in mbar and inHg. The weather forecast and temperature are also displayed. With all the fancy stuff aside there are also the standard features like a watch function, alarm, standard chronograph, backlight system, a mineral glass lens and the whole thing is water resistant up to 30 meters.
