The award-winning Suunto Lumi is a beautifully designed, yet fully equipped outdoor product equally suited to trekking in the wilderness as it is for urban leisure. With a variety of useful functions and accessories, you can style your Lumi to fit any occasion. Altimeter Accurate to 30,000 feet, the Suunto Lumi altimeter is a valuable tool for mountaineering, skiing and wilderness travel. It displays your current elevation, shows how much youve climbed or descended and records your entire session. Barometer A veritable weather station on your wrist, the Suunto Lumi barometer measures and records air pressure to help you predict changing conditions, from sunny skies to hair-bending electrical storms. Compass The digital compass on the Suunto Lumi is a great tool for keeping track of direction while skiing, hiking or exploring a new city. Automatic Alti/Baro switch The Suunto Lumi features an automatic Alti/Baro switch that senses movement or lack thereof, switching between altimeter and barometer accordingly. When youre climbing, it records changes in elevation. And when you stop to rest, it records changes in barometric pressure. A drop in air pressure while youre sleeping under the stars will be recorded for what it really is : a change in barometric pressure, not altitude. Storm Alarm Activated by a rapid drop in air pressure over a three-hour period, the Storm Alarm sounds and flashes, letting you know that something unpleasant is fast approaching. Day counter You cant stop the march of time, but you can keep it from marching over you. Whether youre expecting a visit, a vacation or even a baby, the Suunto Lumi Day Counter keeps you abreast of an upcoming event. Watch Suunto Lumi watch functions include time, dual time, date, alarm, and predicted times for sunrise and sunset for over 400 locations worldwide.
