watchOS 27 Brings Siri AI to Apple Watch, But Six Models Lose Support After Just 3-4 Years
Apple announced watchOS 27 at WWDC 2026 with AI-powered Siri that finally delivers contextual answers on your wrist. But the update comes with an aggressive compatibility cutoff—dropping Apple Watch Series 6, 7, 8, 9, the original Ultra, and SE 2. That means devices as recent as three years old won't receive further updates, marking a sharp departure from Apple's typical support timeline.
