Apple is narrowing the compatibility window for its upcoming watchOS 27 and iPadOS 27 software releases. While the Apple Watch Series 9 will remain supported, many older models—including several generations of Apple Watch and specific iPad models—will no longer receive these latest operating system updates.
Which Apple Watch models will work with watchOS 27?
The compatibility list for the next Apple Watch operating system has caused significant confusion among users. According to the official Apple website, watchOS 27 is designed to run on the Apple Watch SE 3, Series 11, Series 10, Ultra 3, and Ultra 2.
Initially, this list appeared to exclude several recent devices. However, after users reported successfully installing the watchOS 27 developer beta on the Apple Watch Series 9, Apple confirmed to 9to5Mac that the Series 9 is indeed compatible. This correction provides some relief to owners of that specific model, even though the official website may not reflect the change immediately.
There is also an interesting discrepancy regarding the original Apple Watch Ultra. While it isn’t included in the official compatibility documentation, reports have surfaced of users successfully installing the watchOS 27 developer beta on the first-generation Ultra model.
A significant drop in support compared to last year
This year’s software rollout represents a much steeper “cull” of older hardware than we’ve seen recently. To put this in perspective, watchOS 26 supported the Apple Watch Series 6 and later, as well as the Apple Watch SE (2nd generation) and later. This meant that the list of supported devices remained relatively stable from watchOS 11 through watchOS 26.
With watchOS 27, that stability is gone. Owners of the Apple Watch Series 6, 7, and 8, along with those using the SE 2nd generation, will no longer be able to access the latest features. This includes new tools like the Siri AI app, new workout data insights, and Spanish language support for Workout Buddy.
iPad compatibility changes for iPadOS 27
The software cut extends to the iPad lineup as well. If you rely on an older iPad for school or work, you’ll want to verify your hardware before the iPadOS 27 release. The update will officially end support for the 3rd-generation iPad Air and the 8th-generation regular iPad.
iPad Pro users face even more specific hardware requirements. To run the latest software, you’ll need at least one of the following:
- A 4th-generation 12.9-inch iPad Pro or newer
- A 2nd-generation 11-inch iPad Pro or newer
The hardware lifecycle paradox: iPhone vs. Apple Watch
One of the most striking aspects of this year’s update cycle is the inconsistency in how Apple treats different device categories. There is a noticeable gap between how long an iPhone is supported versus an Apple Watch.
Apple is maintaining support for the iPhone 11 models with iOS 27. This means a smartphone released back in 2019 will still be able to run the latest operating system. In contrast, some Apple Watch models from 2022 will be left behind. This creates a strange scenario where a five-year-old phone can stay current, but a three-year-old wearable cannot.
This trend suggests that Apple may be prioritizing the longevity of its primary mobile devices while accelerating the replacement cycle for its accessories and wearables.
