'It’s the most convenient way to interact with Siri'

Last week, Apple unveiled Siri AI across all its devices at its annual WWDC event. While much time was given to how you'll be able to use Apple's new virtual assistant on iPhone, iPad and Mac, the Apple Watch was overlooked — despite the fact that, according to Apple, it's "the most convenient way to interact with Siri" more often than not.

That quote comes from Apple's own David Clark, senior director of watchOS software engineering. I had the opportunity to ask Clark, as well as Cait Dooley, Apple Watch and Health Product Marketing Manager, about how they see Apple Watch users interacting with Siri AI on their wrists.

Clark said one of the goals of watchOS 27 was "to expand the intelligence story on Apple Watch and make it a true co-partner to Apple Intelligence". It's doing so by being a first point of contact, as a wearable is a convenient place to house a microphone for asking Siri questions.

"We really wanted to make sure the Siri experience is a singular and consistent experience, whether I decide to ask Siri on my wrist a question, or whether I have my phone in my hand and I decide to interact with Siri there. We really wanted to feel like it’s one Siri, that has access to your data and is able to personalise it in a consistent way.

"One of the things that Apple Watch brings to the picture is the fact that it’s on your wrist all day, [so] oftentimes it’s the most convenient way to interact with Siri. You can imagine you’re on the go, your hands are full, you have that quick question for Siri and you can interact with Apple Watch. Of course, with the new Siri app, if you want to continue that conversation or go more deeply into some topic you’re interested in, later on you can pull out your phone and pick up right where you left off.”

Clark gives me an example of a grocery list in a store: with hands full, he's able to ask Siri on Watch for the ingredients he needs for a particular recipe. When he gets a moment, he can then open his phone to view that ingredients list in an easier-to-read way. "Working together is that superpower," he says, "and having it all being consistently driven by your data."

The elephant in the room: watchOS 27 and compatibility

As the announcements were rolling out, however, there was a pall over watchOS 27 as it was announced that five older models — the Apple Watch Series 6, 7, 8, the SE 2 and even the original Apple Watch Ultra — won't get watchOS 27, and so won't get the new Siri AI features. They'll only receive basic security support going forward.

I asked the watchOS team exactly why so many watch users have been left high-and-dry.

"With every software release across every single one of our platforms, we always want to ensure that you have the best experience, so we make power and performance a priority," said Dooley.

"The great new features in watchOS, including the capabilities of SIri AI and the new tap gesture, work best with the processing power that is in Apple Watch Series 9 and later, Ultra 2 and later, and SE 3. Older devices can still be paired with iPhones that are running the latest software and continue to receive security updates, so they can continue to have a great Apple Watch experience."

So while you'll be able to use older your watch with iPhones running Siri AI-powered software, you won't be able to access the new and smarter assistant on your watch. Although Dooley and Clark wouldn't confirm this is the case, it's likely only Apple Watches running Apple's powerful S9 and S10 chips can handle the technical demands of Siri AI.
