I have had two Timex Ironman (Ironmen?) in the last 14 years and the last one survived ten of those years. I really hate charging yet another thing so a ten-year battery life is pretty good (of course it depends on how much you use the Indiglo feature, primarily). They’re also much more durable than Fitbits, which are my only other data point.
