Apple has confirmed that watchOS 27 will drop support for the Apple Watch Series 9, the first-generation Apple Watch Ultra, and the second-generation Apple Watch SE. This update marks a significant shift in the company’s software lifecycle, as Apple is effectively ending support for devices powered by the S9 or S10 chip, despite these models being relatively recent additions to the wearable lineup.
Which devices are compatible with watchOS 27?
Compatibility for the new software is now restricted to a smaller set of hardware. According to official confirmation from Apple as of June 8, 2026, the only devices that will run watchOS 27 are the Apple Watch Series 10, Series 11, Ultra 2, Ultra 3, and SE 3. Notably, this exclusion policy targets specific chipsets rather than just release dates; for instance, the Apple Watch Ultra 2 remains supported, while the Series 9—which shares the same S9 chip—does not.
Why this update represents a major shift
This move is the most aggressive reduction in software support for Apple wearables to date. To put this in perspective, watchOS 26 maintained the same support list as watchOS 11, covering the Apple Watch Series 6 and later, as well as all Apple Watch Ultra models. By moving to watchOS 27, Apple is cutting off four years of device support in one release cycle. This departure from previous update patterns suggests that Apple is tightening its requirements for the latest generation of its wearable software.
