watchOS 27 Expected Apple Watch Compatibility List Ahead of WWDC26

Apple has not yet announced the official compatibility list for watchOS 27, but expectations are forming ahead of WWDC26 based on current watchOS 26 support and Apple’s update pattern. The main question for Apple Watch users is which models may receive the next major software update.

watchOS 27 is expected to be introduced during Apple’s WWDC26 event, scheduled for June 8-12, 2026. Apple is expected to announce its new operating system versions at the event and share upcoming software changes for Apple Watch.

Apple Watch Models Expected to Support watchOS 27

The official list of watchOS 27 compatible Apple Watch models has not been published. The models below should therefore be viewed as an expected list based on current watchOS 26 support, not as confirmed information.

• Apple Watch Series 6
• Apple Watch Series 7
• Apple Watch Series 8
• Apple Watch Series 9
• Apple Watch Series 10
• Apple Watch Series 11
• Apple Watch SE 2
• Apple Watch SE 3
• Apple Watch Ultra
• Apple Watch Ultra 2
• Apple Watch Ultra 3

The list is expected to become official after Apple’s announcement. For older Apple Watch models, the final decision will become clear after the WWDC26 updates.

Apple Watch Models That May Not Receive watchOS 27

Apple Watch models that may not receive watchOS 27 include older devices with less recent hardware. The support status of Apple Watch Series 4, Apple Watch Series 5, and the first-generation Apple Watch SE remains uncertain.

The shift toward newer models in watchOS 26 support suggests a similar approach may continue with watchOS 27. However, it would not be accurate to make a definitive statement before Apple releases the official list.

Which iPhone May Be Required for watchOS 27?

Apple Watch updates do not depend only on the watch model. The paired iPhone model and iOS version must also be compatible with the update.

For watchOS 26, the requirement is expected to include an iPhone 11 or newer running iOS 26. A similar or newer iPhone requirement may be set for the watchOS 27 update. Apple’s official announcement will clarify this condition.

Expected Features in watchOS 27

watchOS 27 is expected to bring improvements in health, activity, performance, and interface features. Updates related to AI-powered suggestions, health tracking, Siri integration, and watch faces may also be discussed.

These features have not been officially confirmed, so they should not be treated as final. Apple’s WWDC26 presentation will reveal which features watchOS 27 will include and which Apple Watch models will support the update.

When Will watchOS 27 Be Released?

Based on Apple’s previous software schedule, the watchOS 27 developer beta is expected to be released after WWDC26. A public beta may arrive in the summer, while the final version could be released in the fall.

Apple has not announced the exact release date. The official schedule for the Apple Watch watchOS 27 update is expected to be shared after the event.
