Why Apple Is Dropping Support for Old Apple Watches

You paid premium for a watch. Now Apple is leaving some of those devices behind. Ouch.

At WWDC, Apple unveiled watchOS 27 and a clear cutoff: several older Apple Watch models will not receive the full update when it ships this fall. That list includes the original Apple Watch Ultra from 2022 — a device that once carried a $799 price tag — and a number of Series and SE models that many people still use every day. Those watches will only get essential security updates going forward.

Apple's explanation was blunt and practical. Cait Dooley, who manages Apple Watch and Health product marketing, told reporters that the newest features demand more horsepower and smarter power management than earlier chips can deliver. On-device Siri powered by advanced AI, the new tap gesture and other system improvements are tuned for the silicon and sensors inside Apple Watch Series 9 and later, Ultra 2 and later, and the third-generation SE.

Translation: it is not just about having enough CPU cycles. These features lean on neural engines, sensor fusion, and tighter battery budgets. Hand an old watch a modern, AI-heavy workload and you get sluggish responses, drained batteries, and a worse experience overall. Apple frames the decision as a quality control move — better to limit features than ship them in a way that undermines daily use.

That does not mean older watches stop working. They will still pair with iPhones running the latest iOS and receive security patches, which keeps them safe and functional for core tasks like workouts, notifications, and third-party apps that continue to support older watchOS versions. But the shiny additions in watchOS 27 — especially anything relying on on-device AI — will be off-limits unless you move to a newer model.

If you own an Apple Watch Series 8 or older, the original Ultra, or an SE prior to SE3, you are the one affected. Decisions are personal. Keep the watch and accept a proven, stable experience. Or upgrade to tap into Siri improvements, gesture controls, and smoother performance. Either way, Apple has made clear where it thinks the line should be drawn.

So what will you choose when fall arrives: stick with a trusty wrist companion, or step up to hardware that was built with today’s AI in mind?
