I bought the Apple Watch on launch day. Space Grey Sprt. Wore it pretty much everyday since then. Few days ago it started acting weird, heart rate would read 200+ all the time, every time the screen would go black it would lock the Watch. It takes 5-10 minutes to boot up when powered up. I think she’s done for... can’t decide if I want another or not...? Might wait for the 3rd generation and see what that’s like!
