My U3 is my 4th watch. I was leery about the clunky look, my arms are skinny. Someone mentioned interference with sleeves, I have a windbreaker with elastic cuff’s and it’s a hassle if I need to interact w/ the watch. I wear mine 24x7 except to charge. I use it mostly to track exercise, health, sleep, and podcasts. I make good use of the action button, my action is a shortcut to a menu of other actions. It’s way more watch than I need, except I really wanted to have a red watch face for sleeping and at night if I’m outside. My first AW had that capability and somewhere along the line it was removed by Apple. It is available in U2 & U3 and the red face is so important to me that it is the primary reason I bought the U3. I’m in my late 70’s, I owe myself a treat and the U3 is it. The red face at night does not blind me if I happen to touch the screen.
