Apple seeded watchOS 27 beta 3 for the Watch Ultra 3, adding Siri AI and new UI features. See how the update changes the watch experience and which devices are
Apple has released watchOS 27 beta 3 exclusively for the Apple Watch Ultra 3, introducing the new Siri AI assistant that can hold back‑and‑forth conversations and draw on personal data and web knowledge [1]. The rollout matters because it signals Apple’s push to bring its next‑gen “Apple Intelligence” to wearables, but it also confirms that older Watch models will miss out on the upgrade.

|---|---|
| Device | Apple Watch Ultra 3 |
| Update | watchOS 27 beta 3 (Siri AI) |
| Availability | Developer beta via Watch app (requires iPhone 15 Pro or later) |
| Dropped support | Series 6, 7, 8, 2nd‑gen SE, 1st‑gen Ultra |
The beta adds a “Siri AI” app that lets the watch converse naturally, pull context from emails, messages and photos, and answer live web queries [1]. To use it, the paired iPhone must support Apple Intelligence—currently the iPhone 15 Pro and newer—so the feature is limited to users with the latest hardware. Apple also refreshed the Dynamic app grid to surface Siri‑suggested apps and introduced smarter Smart Stack suggestions, while core utilities like Find My and Workout Buddy receive UI tweaks and new metrics [1].
Apple’s WWDC 2026 announcements confirmed that watchOS 27 will not support the Apple Watch Series 6, 7, 8, the second‑generation SE, or the first‑generation Ultra [3]. This “bloodbath” of dropped support leaves millions of existing watch owners on older software, potentially nudging them toward newer hardware or the Ultra 3 upgrade path. Competitors such as Samsung and Google, which continue to support a broader range of wearables, may find an opening among users forced to stay on legacy Apple devices.
The beta underscores Apple’s strategy to embed its AI stack across the ecosystem, but the limited device eligibility raises questions about how quickly the broader user base will benefit from the new capabilities.

Siri AI on watchOS 27 beta 3 offers contextual awareness, natural language understanding, and the ability to continue conversations across linked Apple devices.
The Siri app requires an Apple Watch Series 9, Apple Watch Ultra 2, Apple Watch SE 3, or newer.
The third developer beta builds were released in late June 2026, with watchOS 27 beta 3 arriving on June 25.
Apple advises against installing developer betas on primary devices, recommending they be used only on secondary hardware by developers.
The third round aims to refine the operating systems before the public release later in 2026, allowing developers to test changes and report issues.
