Available: now · since June 8, 2026
See the stepsThe watchOS 27 beta installs from the Watch app on your iPhone — no profile file. But first, one hard rule: an Apple Watch can’t be downgraded. This guide covers both the Developer and Public Beta step by step, what your iPhone needs first, which watches are supported, troubleshooting, and the honest truth about removing the beta.
First update your iPhone to the iOS 27 beta — watchOS 27 won’t appear until you do. Then on the iPhone open the Watch app → General → Software Update → Beta Updates, choose watchOS 27 Developer Beta (or Public Beta from July), put the Apple Watch on its charger at 50%+ battery with the iPhone nearby on Wi-Fi, and tap Download and Install. It’s free with any Apple Account. ⚠️ Remember: you cannot downgrade an Apple Watch, so only use a secondary watch.
Unlike iPhone, iPad and Mac, the Apple Watch has no user-accessible recovery mode. Once it’s on a watchOS beta, you cannot restore it to the stable version yourself — it stays on beta builds until the public release ships in the fall. The only early exit is paid Apple service. Only install this on a secondary Apple Watch, never the one you rely on for health and daily use.
Two free routes · pick one
Both are free and install the same way through the Watch app. Because the watch can’t be downgraded, stability matters even more here than on other devices.

There’s no Settings app on the watch for this — you pick the beta in the Watch app on your iPhone, and it pushes to the Apple Watch.
This opts your paired Apple Watch into pre-release updates. No profile file is installed.
In the Watch app → General → Software Update → Beta Updates, choose watchOS 27 Developer Beta.
The watch must be on its charger at 50%+ with the iPhone nearby. It restarts when done.
Method 1 · available now
watchOS 27 Developer Beta 1 went live on June 8, 2026, alongside iOS 27. It installs from the Watch app — free, no profile file.
This is required — watchOS 27 will not appear until the paired iPhone is on the iOS 27 beta. Follow our iOS 27 install guide, then come back.
Because there’s no downgrade, don’t install on the watch you rely on. A spare Apple Watch keeps your daily health tracking and notifications safe.
On the iPhone, open the Watch app and go to General → Software Update → Beta Updates.
Tap watchOS 27 Developer Beta so it shows a checkmark, then go back to the Software Update screen.
Put the Apple Watch on its charger with at least 50% battery, keep the iPhone nearby on Wi-Fi, and tap Download and Install. It takes 30–60 minutes and the watch restarts on its own.
Method 2 · expected July 2026
A few weeks after the developer build, Apple opens the Public Beta — the same watchOS 27 with the worst early bugs fixed. Given the no-downgrade rule, this is the route we recommend.
Sign up free at beta.apple.com and install the iOS 27 public beta on the paired iPhone first (expected July 2026). The watch beta won’t show up otherwise.
Same rule — the Apple Watch can’t be rolled back, so install only on a spare watch.
On the iPhone, open the Watch app and go to General → Software Update → Beta Updates.
Choose watchOS 27 Public Beta, then go back to the Software Update screen.
Apple Watch on charger at 50%+, iPhone nearby on Wi-Fi, then tap Download and Install.
watchOS 27 trims the list — six models are in, five older ones are out.
If your watch is supported, watchOS 27 will appear in Beta Updates once your iPhone is on iOS 27. If not, the option stays hidden — that’s expected.
The snags people actually hit installing watchOS — and the fix for each.
The single most common cause: your iPhone isn’t on iOS 27 yet. Update the iPhone first. Then confirm the watch is supported and signed in with the same Apple Account, and reopen the Watch app.
The watch needs to be on its charger at 50%+ battery with the iPhone nearby on Wi-Fi. Put it back on the charger, keep both devices close, and try again.
watchOS updates are slow — 30 to 60 minutes is normal, and the progress bar can sit for a while. Keep both devices still and on power; if it truly hasn’t moved in an hour, restart both and retry.
If space is tight, remove a few apps or downloaded songs/podcasts from the watch via the Watch app, then start the update again.
There are two very different things here — stopping new betas, and actually going back. Only one is possible on Apple Watch.
In the Watch app, go to General → Software Update → Beta Updates and set it to Off. Your watch stays on its current beta build but stops pulling new ones, and rolls into the stable watchOS 27 when it ships in the fall.
You simply can’t. The Apple Watch has no recovery mode and no user IPSW restore — there is no DFU route like on iPhone or Mac. The only way off a beta early is to send the watch to Apple for service, which is costly and not covered by warranty. This is why a secondary watch matters.
There is no public IPSW or recovery mode for Apple Watch, so there’s nothing to download here — and that’s the whole point. Treat a watchOS beta as a one-way trip until the stable release, and only ever install it on a watch you don’t depend on.
