The Apple Watch Ultra has always been a symbol of cutting-edge wearable technology, designed with adventurers, athletes, and tech enthusiasts in mind. But as the fall 2026 launch season approaches, Apple’s next iteration—the Apple Watch Ultra 4—is generating more buzz than ever before, promising a blend of evolutionary and revolutionary upgrades. Yet, for some current owners, it’s also a season of frustration, as Apple’s support for older Ultra models appears to be waning in the shadow of its latest innovations.
According to multiple reports, including those from Gizmodo and Stuff, the Apple Watch Ultra 4 is expected to debut alongside the iPhone 18 lineup in September 2026. This aligns with Apple’s longstanding tradition of unveiling major products in the autumn. The excitement is palpable, as leaks and rumors suggest the Ultra 4 will feature a thinner, more streamlined design—a direct response to feedback that the current 49mm Ultra can be cumbersome for everyday wear. By shaving off some of that bulk, Apple aims to make its flagship wearable more accessible and comfortable, potentially attracting new users who previously found the Ultra series too hefty for their wrists.
Design, however, is just the tip of the iceberg. Health tracking—a hallmark of the Apple Watch family—is set for a major boost. The Ultra 4 is widely rumored to introduce blood pressure monitoring, not as a traditional cuff-based measurement, but as an advanced hypertension alert system. As Stuff reports, this feature could identify concerning trends and notify wearers before potential issues escalate, offering a proactive approach to cardiovascular health. Of course, as with any health-related technology, regulatory approval is still required before the feature can roll out broadly.
Other anticipated health features include enhanced heart rate tracking, improved sleep analysis, and better workout and recovery metrics. These upgrades are expected to stem from a redesigned sensor array on the underside of the watch, possibly arranged in a new ring-style layout. As Geeky Gadgets notes, this reconfiguration could allow for even more precise readings of heart rate, body temperature, and blood oxygen levels—pushing the device’s reliability and usefulness to new heights for fitness buffs and health-conscious users alike.
Security and convenience are also in the spotlight, with rumors swirling about the integration of Touch ID for the first time in the Apple Watch lineup. This fingerprint authentication system would allow users to unlock their devices or authorize payments with a simple touch, reducing reliance on passcodes or paired iPhones. For those who value both privacy and ease of use, this could be a game-changer—streamlining daily interactions and adding an extra layer of protection.
Battery life, a perennial concern for smartwatch users, is another area where the Ultra 4 is expected to shine. Thanks to a new-generation S-series chip and advancements in display technology, the device could deliver multi-day usage without increasing its size. While no credible leaks suggest a physically larger battery, the focus is clearly on efficiency: less time tethered to a charger means more time for adventure, tracking, or simply going about your day uninterrupted.
Speaking of the display, improvements are rumored here as well. The Ultra 4 may offer a brighter, clearer, and more durable screen, making it easier to read in bright sunlight, during intense workouts, or in everyday situations. Some reports even hint at an increase in usable screen real estate, providing more space for maps, notifications, and health data—without sacrificing the rugged identity that defines the Ultra line.
But while Apple is pushing forward, it’s also drawing a line in the sand for older devices. As reported by Gizmodo, the original Apple Watch Ultra from 2022, which retailed for $800, will not receive the upcoming watchOS 27 update. In fact, only the Apple Watch Series 9 and later will have access to the new software enhancements. This leaves out not just the original Ultra, but also Series 6 through 8 and the Apple Watch SE 2. The reason? These older models lack the neural processing cores required to run the new AI-powered features—such as Siri’s contextual awareness—made possible by the S9 SiP chip and its four-core Neural Engine.
It’s a tough pill to swallow for owners of high-end devices that are barely four years old. As one Reddit user lamented, “There’s nothing Apple is doing that can’t be tweaked or down-clocked that would prevent [older watches] from running a new OS. We’re not simulating particle collisions on the new OS.” Their frustration is understandable, especially since Apple has a reputation for supporting older devices longer than many competitors. For example, the iPhone 11 from 2019 will receive iOS 27, and even the original HomePod from 2018 will run HomePod Software 27. Yet, the first Ultra is the notable exception—left behind as Apple pivots toward more AI-centric experiences.
This isn’t the first time the original Ultra has missed out. It was already excluded from major watchOS 26 features, such as hypertension notifications and live translation for incoming texts—capabilities reserved for the Ultra 2, Series 9, and later models. Now, with watchOS 27, it won’t even get the new “Modular” watch face, which offers a larger clock and three customizable elements. That particular feature will be available on all three Ultra models, but only the newer ones will benefit from the full suite of enhancements promised by Apple: better battery life, faster Wi-Fi connections, more accurate sleep tracking, and speedier media playback.
For those considering an upgrade, the Ultra 4’s rumored features are certainly enticing. Apple is expected to keep pricing consistent with previous Ultra models, though global economic conditions and component costs could still influence the final sticker price. The company’s focus on innovation—balancing meaningful health and usability upgrades with a refined design—makes the Ultra 4 a compelling prospect for both new buyers and those whose devices are being left behind by software updates.
Still, it’s worth noting that not all industry observers are convinced a dramatic redesign is on the way. Bloomberg’s Mark Gurman, for instance, has suggested that major visual changes across the upcoming Watch lineup may be limited, leaving the true scale of any overhaul up for debate until Apple’s official announcement. As always, leaks and rumors should be taken with a grain of salt, but the consensus is clear: the Ultra 4 is shaping up to be the most significant upgrade to the Apple Watch Ultra family yet.
Whether you’re a die-hard Apple Watch fan, a health enthusiast, or someone simply looking for a reliable, stylish wearable, the Ultra 4’s blend of form and function is poised to set a new standard in the smartwatch world. For those clinging to older models, the winds of change are blowing—and Apple’s message is clear: the future of wearables is thinner, smarter, and more AI-driven than ever before.
