Apple confirmed at WWDC 2026 that the Apple Watch Series 6, 7, 8, SE 2, and the original Apple Watch Ultra will not receive watchOS 27. This marks the most significant support cutoff in Apple Watch history, cutting off three full years of device releases in a single software update. Older watches paired with an iPhone running the latest software will continue to work and receive security updates, but they will be excluded entirely from new features.
watchOS 27 will run on the Apple Watch Series 9 and later, the Apple Watch Ultra 2 and later, and the Apple Watch SE 3. Apple explained the cutoff through performance requirements tied to the new software’s flagship features.
Performance requirements and new features
Apple Watch and Health product marketing manager Cait Dooley attributed the limitation to processing power constraints. She said that “great new features in watchOS, including the capabilities of Siri AI and the new tap gesture, work best with the processing power that is in Apple Watch Series 9 and later, Ultra 2 and later, and SE 3.” The company’s framing emphasizes hardware capability rather than a business decision to force upgrades.
watchOS 27 brings several additions beyond AI capabilities. This includes new dynamic app grid and improvements to Workout Buddy. Siri AI will be available on compatible watches, though the feature won’t appear in the beta version but will roll out later in 2026.
In an interview with TechRadar, Senior director of watchOS software engineering David Clark framed the update as central to Apple’s vision for the watch. He described one goal of watchOS 27 as to “expand the intelligence story on Apple Watch and make it a true co-partner to Apple Intelligence.” The watch, he noted, is often “the most convenient way to interact with Siri” since it’s on the wrist all day.
The disparity with iPhone support
Whether the Series 9’s processor genuinely requires capabilities the Series 8 lacks, or whether this represents an engineered cutoff to drive upgrades, remains less transparent. The disparity between iPhone support and Apple Watch support raises questions about the strategy. The iPhone 11 will receive iOS 27 compatibility, yet the Apple Watch Series 9 from 2023 will not get watchOS 27. That six-year gap in iPhone longevity compared to the three-year watch cutoff suggests factors beyond raw processing power may be at play.
Public beta testing typically begins in July, with the full release scheduled for September 2026 across compatible Apple Watch models. Older watches won’t benefit from new features, but Apple’s guarantee of continued security updates means they remain functional alongside current iPhones. The announcement marks a turning point in how aggressively Apple manages the Apple Watch product cycle.
