Build identity

The retained release evidence identifies 24R5289n as a watchOS 27 prerelease build associated with Beta 1. The identifier is platform-scoped even when another operating system uses the same characters.[1][2]

Milestone relationship

This single build record links the existing Beta 1 route without duplicating a build document. The cited Apple release entry establishes the build and developer-beta milestone; it does not establish a public release.[1][2]

Research boundary

Apple’s WWDC announcement places the first developer-testing availability on the same date.[1][2]
