Apple Releases watchOS 27.0 Developer Preview Beta 2

Apple has rolled out the second developer beta of watchOS 27.0 to registered developers, bringing the internal build number to 24R5305g. The update lands fifteen days after the first beta or release candidate, maintaining a steady cadence as Apple pushes toward a public release later this year.

On the compatibility front, all Apple Watch models that support watchOS 27 are eligible for this beta update, with the sole exception of the Apple Watch Ultra 3. Notably, initial reports from multiple outlets indicate that no new user-facing features have been spotted in Beta 2, suggesting this build is primarily focused on under-the-hood refinements and stability improvements.

Developers enrolled in the Apple Developer Program can install the update by navigating to Settings → General → Software Update on their Apple Watch. Public beta testers registered through the Apple Beta Software Program can access the update through the same path once the public beta becomes available.

For context, the first watchOS 27 Beta (build 24R5289n) was released on June 9, 2026. IT-NEWS will continue to monitor the beta cycle for any notable changes or feature additions as subsequent builds arrive.
