watchOS 27 drops support for plenty of Apple Watch models and it’s quite frustrating

watchOS 27 drops the Apple Watch Series 8, Ultra 1, and SE 2 from its compatibility list, cutting off devices that launched just four years ago.

WWDC 2026 brought the usual wave of software announcements, and watchOS 27 was among them. The update is scheduled to arrive this fall with expanded Siri integration and new Apple Intelligence features. What Apple buried alongside the feature list was a compatibility cutoff that leaves a significant chunk of Apple Watch owners out in the cold.

The models that didn’t make the cut

The Apple Watch Series 8, first-generation Apple Watch Ultra, and Apple Watch SE (2nd generation) will not support watchOS 27. That means only the Series 9, Series 10, Series 11, Ultra 2, Ultra 3, and SE 3 will get the update. This means Apple is drawing a line at devices equipped with the S9 chip or newer.

For context, watchOS 26 held the same support floor as watchOS 11 before it, covering the Series 6 and later, the SE (2nd generation) and later, and every Apple Watch Ultra. Dropping three generations in one update is a significant break from that pattern, and owners of devices that were fully supported just one software cycle ago will find themselves shut out when watchOS 27 rolls out later this year.

What watchOS 27 brings to supported devices

The update will offer meaningful additions for compatible hardware. Siri will become central to the watchOS 27 experience, along with new Apple Intelligence features integrated into the Smart Stack. A Dynamic App Grid will surface recently used apps, and ID integration will arrive natively on the wrist. However, running Apple Intelligence on Apple Watch will require pairing with an iPhone 15 Pro, Pro Max, iPhone 16 or newer to handle the processing load.

For owners of an Apple Watch Series 8, Ultra 1, or SE 2, the update’s feature list is beside the point. All three dropped models launched in 2022, making them four years old when watchOS 27 arrives this fall, which isn’t a reasonable lifespan for a device that cost upward of $400 at launch. Apple has not explained the accelerated cutoff, or whether buyers should expect the same going forward.

Bloomberg reports that preorders open July 16, with shipping scheduled to begin in October. The ring can collect readings during the day and overnight, then display the results through an iOS or Android app.

HTC’s VIVE Eagle smart glasses could finally be heading to the US. Apparently, Amazon got the memo before HTC was ready to share it.

Notebookcheck spotted six versions available for preorder at $499, each carrying a September 1 release date. Amazon has since pulled the pages, so new orders are closed and anyone who already placed one is left wondering whether it still counts.

Don’t expect smartwatches and fitness bands with replaceable batteries anytime soon
Turns out even the EU thinks your smartwatch is too small for a battery swap.
Wristwatch, Arm, Body Part

The EU has a habit of pushing tech companies to adopt meaningful changes in their product. It's the reason your iPhone finally has a USB-C port, and it's also why companies now have to offer spare parts and repair support for electronics for several years after launch. So naturally, many of us assumed wearables were next in line for mandatory swappable batteries. Turns out, the EU just went the other way.

So what did the EU announce?
