I have an armitron from Target that I wear to work (ambulance), and swimming. I've only had it for like 6 months (it was a desperation purchase when I needed a watch - ordinarily, I hate digital watches for the ambulance) but it's holding up nicely. Was about $12 I think. I've liked Timex watches as well. I actually have a dirt-cheap one I bought at CVS several years ago that's still chugging away, I had to replace the battery and the LCD screen is slightly damaged from being submerged after said battery change (it, um, probably wasn't meant to have the battery changed). That one was like $5 on clearance, from $8 new. CVS rarely has them. Rite-Aid seems to be the only drugstore/pharmacy that consistently has watches now, for cheap ($10-$18). Target clearance might be a good option, though.
