Will your Apple Watch run watchOS 27? Apple just quietly dropped 5 current-gen watches from supporting the upgrade, including Ultra and SE models — here is the full list
UPDATE 09/06: This article has been updated to reflect that the Apple Watch Series 9, which was originally missing from Apple's list of watches compatible with watchOS 27, has now been added.
Another WWDC, another set of operating systems. This year's WWDC 2026 keynote has been chock-full of highly-advanced AI-powered features, led by a revamped Siri AI designed to work across the whole Apple ecosystem — but these advanced features need devices capable of running them.
Because Apple updates its software each year, users of older versions of the best iPhones, MacBooks and, of course, the best Apple Watches worry their old technology may not get the new update, and thus official support for it would end.
Although there was no mention of compatibility in this year's keynote speech, the official Apple website confirms it that five watches that support watchOS 26 won't be able to make the upgrade to watchOS 27 — presumably because those models can't handle the new Siri AI.
Here are the watches that will still be supported when watchOS 27 lands later this year:
The full list of compatible models are as follows:
• Apple Watch Series 9
• Apple Watch Series 10
• Apple Watch Series 11
• Apple Watch Ultra 2
• Apple Watch Ultra 3
• Apple Watch SE 3
These are the recent models without support for watchOS 27:
• Apple Watch Series 6
• Apple Watch Series 7
• Apple Watch Series 8
• Apple Watch Ultra
• Apple Watch SE 2
The Apple Watch Series' 6, 7, and 8 do not appear on Apple's list of compatible devices. Users running those watches can only expect to receive basic security and maintenance upgrades in the future.
