Over the past 25 years I have owned three Timex Ironman watches. They have been in salt water, mud, and just about anything you can throw at them and they keep running. All of them still run. It's the bands that wear out and then I buy another one. I use the ones with broken bands as kitchen timers. Pop in a battery every few years and you're good to go for literally decades. Another plus is that the buttons work the same for all of them, so I don't have to re-learn setting the time, timer, stopwatch, etc.
