The Apple Watch Ultra 3 is set to launch soon, with an iOS 26 beta 5 image revealing a larger screen. Apple may increase the overall size of the device, potentially allowing for a bigger battery. Alternatively, the Ultra 3 could maintain the same case size with slimmer bezels to support the expanded display.
Ryan Christoffel for 9to5Mac:
Aaron Perris posted on X today about his discovery of a new image in iOS 26 beta 5 that seems to be connected to the forthcoming Apple Watch Ultra 3.
The Apple Watch image has a display resolution of 422 x 514, a slight bump from current Apple Watch Ultra models’ 410 x 502 dimensions (via MacRumors).
Since no existing Apple Watch model offers this 422 x 514 resolution, and Apple Watch Series 10 just got an increased screen size last year, the image appears to be confirmation of a slightly larger Apple Watch Ultra 3 display.

Great find! Noticing that the iOS 26 beta 5 image shows a resolution bump—from 410 × 502 to 422 × 514, raises an interesting question:
Does this imply Apple is slimming down bezels without increasing the case size, or should we expect a slightly larger physical watch face (around 1.98″ vs. 1.93″)?
This subtle shift could dramatically improve usability by giving more content edge-to-edge while preserving the Ultra’s rugged footprint. Curious what fans and experts think!
