Well how long do you expect a $60 fitness tracker to last?
Garmin makes a bunch of different lines that can be used for fitness tracking. So do other brands.

The Garmin Fenix line looks pretty much like a real watch.... what ever that is nowadays. So you could get one of those and put your real watch in the drawer for your estate sale later.
Regardless, if you want something that's going to last, I'd up your budget to at least the $150 if not $200 plus level. My son has a Vivosmart that he got in 2016 and it's still going strong even when being worn every day doing physical labor. He has had to replace the bands, but I had to do that periodically with my real watches BITD of wind up watches.
