Good, inexpensive fitness trackers?

I’m looking for a watch that can track my heart rate, stay on my tiny wrist, and that doesn’t cost a lot only to break frequently. Fitbit is….no longer meeting that criteria and was honestly out of my budget to begin with, but i am nervous about spending money again on something random that could also break just as quickly.

Any recommendations ? I have heard about pinetime, but I don’t have a computer or many technical skills - I couldn’t tell from the website if that device requires setup or tinkering to work? I basically just want to be able to look at my wrist and see my heart rate and what time it is. Nothing fancy, I don’t even really need it to sync to my phone, a long as it works for a few years and isn’t $90.
