Blending classic analog style with advanced outdoor functionality, the Timex men's E-Altimeter expedition watch is a must-have accessory for hikers, skiers, and climbers. The E-Altimeter's primary function is to measure your altitude at any given moment, with an altitude range of -400 to 25,000 feet. With the E-Altimeter, you can determine whether you'll make it down the mountain before the sun sets, or you can better gauge your vertical speed down the mountain--a handy tidbit for competitive skiers. The digital altimeter also recalls your minimum and maximum altitude, letting you record the data for later analysis. And thanks to the versatile display--which shows your altitude in either feet or meters--you don't need to do on-the-fly conversions to determine your correct elevation. The E-Altimeter is also built to last, with a stainless-steel case and bracelet that's water-resistant to 100 meters. Other features include a QuickDate feature, an Indigo night light with a night mode, a mineral glass crystal, and a brushed finish. The E-Altimeter, which comes in a black/black color, offers a 50mm wide case and a 22mm wide lug.
