The upcoming Apple Watch Ultra 3 is shaping up to be the most advanced rugged smartwatch Apple has released to date, according to newly discovered details within the iOS 26 beta. A slight but meaningful increase in display size, enhanced connectivity features, and new health monitoring tools are all expected to debut with the next-generation device this fall.
Bigger and Better Display
Developers examining the latest iOS 26 beta found references to a new display resolution for the Apple Watch Ultra 3—measuring 422 by 514 pixels. That’s a modest increase over the Ultra 2’s 410 by 502 pixels, indicating Apple has expanded the screen real estate by thinning the bezels rather than increasing the watch’s overall size.
With the same 49mm titanium casing, the Ultra 3’s screen is expected to measure roughly 1.98 inches diagonally, up from 1.93 inches. The change may seem small, but it will provide clearer visuals, more space for complications, and a smoother overall user interface experience.
Brighter Screen with Faster Refresh Rate
The Ultra 3 is also expected to feature a next-generation LTPO OLED panel, capable of achieving higher brightness levels and improved energy efficiency. The new screen will offer a faster refresh rate for always-on display mode, allowing for smoother animations and quicker responsiveness while preserving battery life. This could be particularly beneficial for outdoor athletes or users navigating in bright sunlight.
Satellite Messaging and 5G RedCap
One of the most significant rumored additions is satellite-based messaging. This feature would allow users to send texts and possibly emergency alerts even when they are completely outside cellular and Wi-Fi coverage—a game-changer for hikers, travelers, and off-grid adventurers.
In addition, the Ultra 3 is expected to support 5G RedCap, a streamlined version of 5G designed for wearable devices. This would allow for faster data connections without draining the battery, enabling standalone streaming, GPS usage, and real-time notifications without needing to be paired to an iPhone.
New Processor and Health Features
At the core of the Ultra 3 will be a new processor—likely the S10 or S11 chip—bringing improved performance, faster app launches, and greater integration with watchOS 12. Apple is reportedly focusing on optimizing energy efficiency alongside processing speed.
On the health front, a new hypertension monitoring feature may debut. While not intended as a replacement for medical-grade blood pressure monitors, this capability could alert users to elevated blood pressure trends based on continuous biometric data.
Launch Timeline and Price Expectations
Apple is expected to unveil the Apple Watch Ultra 3 in early September, likely alongside the iPhone 17 lineup and the Apple Watch Series 11. Pricing is anticipated to remain consistent with previous Ultra models, starting around $799 in the U.S. and equivalent in other markets.
