pointy_end,
My suggestion is to go with a Timex Ironman watch. There are many different models from which to choose. They are not too expensive, are water-resistant, quite durable, etc. I bought one with all of the features that I wanted (and then some) for under $40.
You can find ‘em at Zellers, Wal-Mart, or just about any department store.
Cheers.
