I still use a dumb watch (the classic Timex Ironman Triathlon) when I workout sometimes or when I'm coaching and I just need a stopwatch, I have yet to see a smartwatch that makes a very good stopwatch. Even some of the exercise specific smartwatches like the Garmin Forerunners don't do stopwatch as well as a Timex.

As a coach I've been seeing a lot of smartwatches on kids lately that are maybe a little young for a smartphone, they seem to be the go-to choice these days for parents to keep track of their kids. That seems like a decent fit, by the time the watch dies the kid will probably be old enough for a smartphone anyway.
