That would be a bit better. Though I’m guessing you mean quartz movement. A smart-watch with a precision automatic mechanical movement and a computer at least would be useful after the computer inevitably became obsolete. Bonus points if the automatic winding can charge the battery via a small generator, but my guess is that it wouldn’t generate nearly enough current for that.
But it’s still a no-go for someone like me, for whom a watch is a family heirloom (yes, yes, obligatory Pulp Fiction butt-smuggling scene is implied, no need to post it thanks 
). I’m not saying no one should wear a smartwatch, but it shouldn’t be the only way to have proximity unlock on one’s phone.
