The TIMEX Ironman series seems like it would take som abuse, but I have never owned one, so really I don't have a recommendation but a suggestion...
Maybe I'm cheap, but I get the $6 sport watches from the local Target, Wal-Mart, etc. that are waterproof. After a year or two, throw them away.
If you MUST know EXACTLY what time it is, carry a watch in your pocket or backpack.
