Want to try watchOS 26 beta on your Apple Watch? Here’s how to download and install the developer beta, plus which models are supported.
What You Need Before Installing
To get watchOS 26 beta on your Apple Watch, your iPhone must first be running the iOS 26 beta. Apple requires this because the devices need to stay in sync with each other during the update process.
Also important: once you install the beta, you can’t revert to the public version. So only proceed if you’re okay with living the beta life for the next few months.

If your watch isn’t listed, it won’t support the update.
