If a dinner plate-size wrist computer isn't your style, check out this combo. You get standard functions–time, stopwatch, altimeter, and barometer–in a smart, easy-to-read display atop a shock-dampening aluminum trekking pole.
The watch head is removable, so you can bring it into your tent for alpine starts, or carry it separately–and the bottom has a signal mirror. $130; 1 lb. 7 oz. (pair); altimeterstore.com.
