watchOS 26.6 Beta 1 Now Available for Apple Watch Developers

Apple has started rolling out the first developer beta of watchOS 26.6 for Apple Watch users. The update arrives alongside the first developer betas of iOS 26.6, iPadOS 26.6, macOS Tahoe 26.6, tvOS 26.6, and visionOS 26.6.



The new beta update comes just days before Apple’s upcoming WWDC 2026 event, where the company is expected to introduce watchOS 27 and other next-generation software updates on June 8.



At the moment, Apple has not shared any official release notes mentioning new watchOS 26.6 features or major changes. Early testing is now underway, and more details could surface in the coming days as developers explore the update.

Before installing the beta, make sure your Apple Watch has at least 50% battery and is connected to its charger.




Open the Watch app on your iPhone



Tap General



Tap Software Update



Select Beta Updates



Choose watchOS 26 Developer Beta

You also need an iPhone running the latest iOS 26.6 developer beta to install the watchOS 26.6 beta.



All the changes



So far, no visible new features or interface changes have been discovered in watchOS 26.6 beta 1. The update currently appears to focus on bug fixes, stability improvements, and background optimizations ahead of the next major watchOS release.



We are still testing the update and will report back if any hidden features, battery changes, performance improvements, or new system tweaks are found.



Apple is expected to unveil watchOS 27 during the WWDC 2026 keynote on June 8.
