watchOS 27: Full Supported Devices
Last updated: October 15, 2026
Apple released watchOS 27 on September 14, 2026, for the Apple Watch Series 9 and later, the Ultra 2 and later, and the SE (3rd generation). The latest version is watchOS 27.0.1.
It is one of Apple's biggest cuts: the Series 8 and earlier, the original Ultra and the SE (2nd generation) do not get it. With the new Series 12 and Ultra 4, eight watches are supported.
Your watch needs to be paired with an iPhone running iOS 27, and some features need that iPhone nearby.
