>>2130105F-91W on a zulu strap is what I normally wear /out/. It's small, light, water resistant, and endorsed for field use by Osama's Outdoor Activities Club. I use the alarm and stopwatch sometimes, but usually I just use the clock function, especially when the trees are too thick to see the sky. Having the second hand or digital display would be good for tracking vitals in a wilderness medicine type situation. When I worked as an EMT I preferred high contrast analog second hands to digital displays but digital is fine, too.
