watchOS 26 Beta 1

What watchOS 26 Beta 1 Is

watchOS 26 Beta 1 is build 23U5025e, released on May 26, 2026. It is a pre-release build available through the developer and public beta channels, and it supersedes every earlier watchOS 26 beta.

This is the first build of the watchOS 26 cycle we have on record, which makes it the baseline every later build is measured against.

Beta 1 Build Numbers Across Every Platform

Apple ships each beta wave across its platforms on the same day, usually with different build numbers per operating system. Here is every build we recorded in this wave, taken from Apple's own release feed rather than reposted from elsewhere.

Matching build numbers between two platforms — as iOS and iPadOS almost always have — mean they are built from the same source, which is why their betas behave identically.

How to Install watchOS 26 Beta 1

There is no profile to download. Enrol your Apple Account free at beta.apple.com for the public beta or developer.apple.com for the developer channel, then open the Watch app on your iPhone → General → Software Update → Beta Updates and select the watchOS 26 channel. The build appears in Software Update like any ordinary update.

If you are already on an earlier watchOS 26 beta, this arrives as a normal update and no re-enrolment is needed. Our full watchOS 26 install guide covers the process step by step, and our device pages tell you whether your exact model qualifies.

Should You Install It?

That depends on where this build sits in the cycle and what the device is for. Early builds break third-party apps — banking and workplace apps first — and cost you a week of heavy background indexing. Later builds are progressively calmer.

Whatever you decide, make an archived backup on a computer first. A backup made on watchOS 26 cannot be restored onto the previous release, so it is the only route back with your data intact — our backup guide explains the difference, and our honest assessment covers running a beta on the phone you depend on.

What Comes After Beta 1

Beta 1 is the newest watchOS 26 build we have on record. Based on this cycle's cadence, the next one is due within the next couple of weeks — this page updates automatically when it lands.

Our build history tracks every watchOS build with its date and the gap before it, which is the clearest picture of how a cycle is progressing. The beta calendar guide explains the shape of the year.
