Q: Does the Apple Watch Series 9 support watchOS 27?

Yes. Apple’s website initially omitted it in error. Apple confirmed to 9to5Mac that the Series 9 is fully supported. It will not, however, receive Apple Intelligence features.

Question 1

Will my Apple Watch get watchOS 27?

Accepted Answer

Only Apple Watch Series 9, Series 10, Series 11, Ultra 2, Ultra 3 and SE 3. Everything older is excluded, including the original Apple Watch Ultra and Series 8.

Question 2

Why was the Apple Watch Ultra 1 dropped?

Accepted Answer

The Ultra 1 uses the S8 SiP, built on A13 Bionic architecture from 2019. Apple drew the compatibility line at the S9 SiP (A16 Bionic). The Ultra 2 uses the S9 and survives.

Question 3

Does the Apple Watch Series 9 support watchOS 27?

Accepted Answer

Yes. Apple&#8217;s website initially omitted it in error. Apple confirmed to 9to5Mac that the Series 9 is fully supported. It will not, however, receive Apple Intelligence features.

Question 4

Do I need an iPhone 15 Pro for watchOS 27?

Accepted Answer

No. watchOS 27 installs with any iPhone 11 or later running iOS 27. You need an iPhone 15 Pro or newer only for Apple Intelligence and Siri AI features on the watch.

Question 5

Does AI run on the Apple Watch itself?

Accepted Answer

Siri AI and Apple Intelligence are processed via private cloud computing on the paired iPhone. The Vision framework for image understanding, such as photo cropping and barcode reading, does run on-device on the watch.

Question 6

Will watchOS 27 work in the EU?

Accepted Answer

Yes. The DMA delay affecting Siri AI on iOS and iPadOS does not apply to watchOS. All watchOS 27 features, including Siri AI, are confirmed for the EU.

Question 7

What are the new workout zone features?

Accepted Answer

HealthKit now exposes heart rate and cycling power zones to third-party apps. Developers can read zone configurations, receive live zone updates during workouts, and set custom zone boundaries. This means apps like TrainingPeaks and Intervals.icu could display real-time training zone data natively on the watch.

Question 8

Can I use Workout Buddy without my iPhone?

Accepted Answer

Yes. watchOS 27 allows Workout Buddy to function without an iPhone nearby. Previously, it required a paired iPhone.

Question 9

What happens to my Apple Watch if it's not supported?

Accepted Answer

It stays on watchOS 26. All existing features continue to work. Apple has not confirmed whether security patches will follow, though the company&#8217;s pattern is to provide them for at least one cycle after a device loses major OS support.

Question 10

When will watchOS 27 be released?

Accepted Answer

Developer beta 1 is available now (8 June 2026). Public beta is expected in July. General release is expected in September 2026, likely alongside new Apple Watch hardware.

Question 11

How does Apple Watch support compare to Garmin?

Accepted Answer

Garmin routinely supports devices with firmware updates for considerably longer than four years. Apple has published no equivalent support commitment for the Apple Watch. Samsung guarantees four years of major updates.

Question 12

What is the Foundation Models framework on watchOS?

Accepted Answer

A new Apple developer framework enabling on-device AI features such as glanceable summaries, workout feedback and smart replies. It uses Apple&#8217;s Foundation Models framework with Private Cloud Compute to keep data private.
