Depends on what features you need. For some people the whole idea is that you can take and make calls on your watch, as well as messaging. Sometimes the health tracking stuff requires a proprietary app instead of Gadget Bridge.
The most private watches are glorified notification machines. I got my wife a Garmin Venu and she uses their app. It’s not perfect but they’re fairly private as far as smart watches go. She needs all the bells and whistles so that’s the best I was able to find that is high end.




I wouldn’t say it is irrelevant when there is a worldwide push towards authoritarianism and countless examples of unreasonable search and seizure.
Plus, everyone has their own threat model. It’s almost a meme in the privacy community, but there’s a reason threat modeling and prioritization is step #1. It may not be a big concern to you (in your opinion), but imagine if it didn’t exist for someone who needs it.
