What kind of health features does she want? Garmin doesn’t sell your data, and they actually make the best hardware when it comes to fitness watches, but their app is kinda bare-bones. (Which is a selling point, imo.)
There are also FOSS options on F-Droid if she wants an app only (I think some can sync with branded watches?) And there’s also the Pebble watch that I see threads about sometimes, but I don’t know anything about it personally.

I think it’s designed that way on purpose to not obscure what the objects are.
