I have the Timex Ironman Triathlon, which I got on Amazon (http://www.amazon.com/gp/product/B00...15312?ie=UTF8). I wear it to count laps when swimming (it also does split times, up to 50 laps). The pros are that it is lightweight and the buttons are easy to use, and I think it's really cute. The clock and timer are easy to see while running or biking. It isn't the greatest for swimming, however; first, because to push the split button I have to pause in my swimming for a second; and second, because while the times are in large numbers, the lap number is very small, so I have to stop swimming if I want to check what lap I'm on. It does lots of fancy things involving saving split times or workout times for later and other functions, but I have never tried to learn how to do those things!
