I’ll give you my personal experience, as someone who didn’t wear a watch at all until a few years ago. Got a new job, and we aren’t allowed to be on our phones. I still wanted access to my notifications, to ensure I didn’t miss anything important (family emergency, camera activity at home, etc etc.), so I bought a smart watch. I can give my notifications a quick glance, and if it’s important, I’ll step away and address it with my phone.
