I'm in Air Force ROTC and pledging for the drill team. As such I am required to wear a watch. Does anyone have some suggestions? I've never owned one before. The only requirement is that it have a stopwatch mechanism.
The most practical answer is probably a Casio G-shock. Nearly indestructible, available in several sizes / styles, and also available in a few different price levels.
When I was in ROTC many many many moons ago, I had an Iron Man watch. It did great on all of our field exercises.
