Upgraded 2 days ago from the series 7, and I am in love with it. The form, the screen, the unique face, the band - it’s the perfect watch. I feel much more free now to leave my phone behind and the battery life has been incredible so far. Selling my Seamaster as I’ll never wear it now.
Got one last Friday and absolutely love it. Honestly, I got it because I liked how it looked, couldn't care less all the other shit it does.
Same for me but that battery and form factor have me hooked. I tried on a friends S8 and it seemed so tiny to me. My U1 is going strong and I only take it off to charge while in shower.
