Smart/fitness watch for a tiny wrist?

[Lovemusic33]

I really want to treat myself to a smart watch for my 40th, needs to work on Android, be water proof and track near rate etc, as well as steps/exercise (I walk and swim). Only problem is I have tiny wrists and most of the watches I have seen other people wearing look really bulky.

Can anyone recommend a watch that’s not too bulky and is a bit more dainty 😬?

Garmin Vivoactive 4s in the smaller size. I have one, but so does my SIL and she is really very petite and it doesn't look bulky for either of us

There are fitness trackers aimed at kids which will probably be good for tiny wrists ?

Fitbit Charge series are good and slim on the wrist
