Yikes, according to the Apple website, watchOS 27 is only for Series 10 and above.

Edit: I reckon it’s a mistake on the website. Series 9 and Ultra 2 use the same CPU, yet Series 9 apparently isn’t supported while Ultra 2 is. That makes no sense.

Edit again: Yep, it was a mistake on the website. It’s now been updated to include Series 9. (see screenshots)
