Functionally I haven't even begun to tap it's potential, yet. Aesthetically I find it a bit clunky, not sure I like the square edges of the glass, and the band is kinda lumpy - although it feels super secure. My watches get rough treatment, we'll see. So far, as hard as I try, the glass hasn't shown any scratches. But I love the navigation features (compass, tides particularly), and other familiar functions (my 3rd Apple Watch) are all working seamlessly, perfect. I like the battery life too!
