Visually, the biggest change is the introduction of a newer LTPO3 display with wide-angle OLEDs, something I felt brought a quietly significant improvement to the Series 10 watches last year. What this means, in practical terms, is a display with significantly improved viewing angles as well as better low-power performance. As such, while the Ultra 2 could refresh the information on a watch face once per minute in always-on mode, the newer display tech allows for a lower-power refresh rate at once per minute, which, you guessed it, means the ability to always display something like a ticking seconds hand. For the Ultra design language, the wider display angles are so, so much better, and given the size of the sapphire crystal on the Ultra, much appreciated. Last year, I finally took the leap to the larger, more rugged design and bought an Ultra 2. However, the improved display is single-handedly making me reconsider eventually getting the Ultra 3. It likely should have come to the Ultra last year, but better late than never.
