After unveiling WatchOS 27 at WWDC 2026, Apple made the developer beta version available to users. While most watch users will receive a free software update to iOS 27 this fall (though availability may vary by carrier, region, and local regulations), you can get access as early as right now in a few simple steps.
WatchOS 27 is the successor to WatchOS 26, the latest operating system for Apple's lineup of smartwatches. Notably, the WatchOS 27 software will not be available for the Apple Watch SE (2nd generation), Apple Watch Series 6, 7, 8, and 9, and the first-gen Apple Watch Ultra.

If you're interested in being one of the first to test the new WatchOS 27, you can now install the developer beta on your device, followed by the public beta in July. Remember that beta versions always come with bugs or glitches, so ZDNET recommends backing up your data and keeping an open mind.
This WatchOS won't be flawless, but it does come with some new upgrades like a dedicated Siri app, a new dynamic app grid, a single-tap gesture to open a Smart Stack widget, more fitness insights with Workout Buddy, enhanced cycle tracking, and more.
