I got a HUAWEI Band 4 for Christmas.
It's pretty small and affordable, but seems to work well.
I don't like the smartwatch, they're all or nothing and I like wearing a traditional watch, but this is small enough to not be intrusive, while tracking steps, sleep and heart rate.
There's a Pro model with more features too, but the basic one does what I want.
Available on Amazon.

PS ETA - I've worn cheap step counters on my right wrist for a good few years now - My favourite was one with no screen (original MiFit) that simply linked to my phone, but sadly nothing that simple seems to be available any more. The battery lasted most of a month on a single charge with those (I killed two diving with them - The pressure seemed to do it, as both died in a drysuit, although I accidentally dived in one in a wetsuit and it was fine!).
