What i love about smart watches: 
- Utility like you mentioned
- Flexibility to choose from a variety of watch faces to fit whatever occasion 
- Serve as a prompt to lead a healthier lifestyle (closing the rings, ease of activating mindfulness exercises that are like 5mins, 1min which is a great reminder to slow down sometimes) 
- So useful when i'm driving to take/make calls and activate siri 

What i don't like about the smart watches: 
- Too casual for certain occasions, (leather strap/bracelets might help dress it up a tad)
- We collect watches for a reason right?! - gotta wear them out right? 

But of course as a everyday watch selection, my go to would still be the Apple watch.But the way i see it is that helps me build a watch collection more intentionally; like going for specific watch dials, heritage, functions etc. (which is great for the pocket as well 👍)
