If you're not looking for something mechanical, I'd highly recommend the St. Moritz line - I have the Titan II chronograph, which is pretty much indestructible. Titanium case and strap. It may be a little over your budget, but its little brother, the Pathfinder may fit, and its a great watch, too. Bone tough. Edited for spelling, and to add an image.
