I've just recently got an Apple Watch, and for me it's a net positive. I've turned off almost all notifications on my Watch, so I don't have the problem with constant notifications.
It really helps me to get some visibility into my health, and closing the rings does motivate me to work out more. I also love the "stand up" notifications, that get me to get up and take a short break from work.
I'm also looking forward to longer term trends, which I think will help me to see if I'm going in the right direction or not =)
Edit: I was not a watch wearer for the past 10 years. The Apple Watch shouldn't be seen as a watch, but as a health device.
