Siri and Apple Intelligence headline Apple's next major smartwatch update—discover what else is new in this guide
Apple’s WWDC 2026 keynote was a departure from the norm. Instead of the usual segment-by-segment breakdown detailing exactly how your Apple Watch will track your next workout or monitor your heart rate, the Cupertino brand spent almost its entire presentation focused heavily on Siri and the broader rollout of Apple Intelligence.
This hyperfocus on AI means its smartwatch ecosystem is heading into the next software generation a bit blind when it comes to traditional health and fitness overhauls.
However, beneath the overarching AI narrative, Apple officially confirmed the arrival of watchOS 27 and provided a clear picture of how artificial intelligence will live on the wrist later this year.
This guide serves as the hub for everything you need to know about the next Apple Watch update, including the rollout of developer and public builds, compatibility demands, and all the exciting features coming this fall.
The final, polished version of watchOS 27 will almost certainly roll out globally in September 2026. Interestingly, although the Digital Markets Act (DMA) will delay Apple’s rollout of the revamped Siri AI on iOS and iPadOS in the EU later this year, watchOS is confirmed to be unaffected .
So, with that, we’re still expecting the software rollout to coordinate with the arrival of Apple’s next-generation hardware line, which should include the Apple Watch Series 12 (and perhaps even an Ultra 4).
And because the WWDC 26 keynote lacked the typical granular breakdown of upcoming native apps and upgrades, we may see Apple quietly reveal specific sports and wellness upgrades via developer beta document drops over the summer.
