The Apple Watch Ultra 2 Has The Brightest Display

Another feature that makes the Apple Watch Ultra 2 stand out from the pack is its display.
While the Apple Watch Ultra looks way bigger than the Series 9, the display is only about half a millimeter larger diagonally (1.9 inches on the Series 9 versus 1.92 inches on the Ultra 2). That’s enough to fit a little more text on the screen, but it’s not as much of a difference as you’d think at first glance.
However, the Apple Watch Ultra 2 screen really stands out because of its brightness. It can reach 3,000 nits, which is 50% brighter than the Apple Watch Series 9 and the first-generation Apple Watch Ultra.
This makes the Ultra 2’s display the brightest you’ve seen on any Apple Watch, and you can see it perfectly even if you’re outside. Plus, this means the Ultra 2’s flashlight is also super bright.
