Overview

  • The iOS 26 developer beta 5 contains an image referencing a 422 × 514 pixel resolution that does not match existing Apple Watch Ultra models.
  • The increase over the Ultra 2’s 410 × 502 display could stem from a 3 percent larger screen or from reducing bezel width while retaining the same case dimensions.
  • Analysis suggests the new pixel count would translate to about a 1.98-inch diagonal panel if pixel density remains unchanged.
  • Rumors point to satellite messaging capabilities, a faster LTPO3 refresh rate, a new SiP chip, and potential blood pressure detection.
  • Apple is widely expected to unveil the Apple Watch Ultra 3 at its September event alongside the iPhone 17 lineup and Series 11 watches.
