@8d17c883 I agree. That said, once the universe runs out of working Pebbles, a watch with reflective, always on screen like the bangle.js2 is workable - it has haptic feedback that helps when navigating menus partially obscured by finger. (Still: Buttons win, 100%)

My #Coros watch has a nice 1-Button/1-Dial handling. Simple, yet effective.
