Greaser is right about Casio for a tough watch.

Depending on preference Casio, Timex, and Citizen probably all have models that would work. I like the eco-drive Citizen because they don't need batteries (solar), but they are more costly and maybe not as tough as a Casio G-shock. The higher end g-shocks sync to the atomic clock and have solar charging, but then you are in the $100+ range.
