Apple clarifies the situation regarding watchOS 27 not being available for several models, partly attributing the decision to AI.

      Siri AI on watchOS 27 requires capabilities that older Apple Watch models lack.

      Apple Watch has received its most significant software update in years with watchOS 27, but five models will miss out on this upgrade.

      If your model isn't included in the compatibility list, Apple provides a reason that might seem plausible, though it doesn’t make the situation any easier to accept.

      So, which Apple Watch models are excluded from watchOS 27?

      Five models: the Apple Watch Series 6, 7, 8, the SE 2, and even the original Apple Watch Ultra.

      With watchOS 27, these models will only receive fundamental security updates and will not be able to use the new Siri AI features or the new tap gesture. The models that are eligible are the Series 9 and later, Ultra 2 and later, and the SE 3.

      This situation feels unusual given Apple’s history of providing extended software support for its devices. TechRadar addressed this with a challenging question.

      They asked Cait Dooley, Apple Watch and Health Product Marketing Manager, why so many models are not included in the watchOS 27 update.

      Is your older Apple Watch still able to use Siri AI?

      “With every software update across all our platforms, we always strive to ensure the best experience for users, thus prioritizing power and performance,” Dooley replied.

      She noted that the new Siri AI and tap gesture features “perform optimally with the processing power” of the supported models. While not stated directly, it appears Apple is setting a Siri AI limitation based on the S9 chip.

      If you have an incompatible model, there is a positive aspect. Older Apple Watches can still connect with an iPhone that operates Siri AI. Therefore, you can utilize your phone to access Siri AI while observing others with compatible models using it on their wrists.
