A guide to downloading and installing the latest software
Downloading the latest Apple Watch update is your key to an enhanced smartwatch experience, with each watchOS version introducing exciting new features.
The next big Apple Watch software update—watchOS 27—was teased at WWDC 2026 in early June. It’s not yet available in full, but it is available via developer beta, with a public beta expected in July.
That means the current watchOS software on most people’s wrists is watchOS 26, which was released in full alongside the Apple Watch Series 11, Ultra 3, and SE 3 in September 2025.
Apple also regularly releases minor updates that fix bugs, add new complications, and drop exclusive watch faces.
Given that knowing how to install new Apple Watch software is an essential skill to accessing all the latest features, we’ve compiled the requirements you need to meet to download the latest watchOS update, as well as provided troubleshooting tips for those experiencing issues.

Apple watchOS 27: Your need-to-know quick guide
Technically, watchOS 27 is now the latest Apple Watch software.
However, since the final version won’t be available to the public until this fall, there are still bits we don’t know about how it will function. And, as ever, features will be dropped and tweaked as it progresses through the developer and public betas this summer and into September.
What we do know is a broad outline of features and, crucially, which Apple Watch models will be able to actually run the software. Here’s what Apple has teased so far:
- Siri AI on the wrist
- Workout Buddy goes phone-free
- Menopause and perimenopause alerts
- A new Smart Stack gesture arrives
- More contextual Smart Stack suggestions
- System and tracking refinements
- More accurate treadmill tracking
- A streamlined Find My app
- Custom Wallet passes
- Private Cloud Computing
Apple Watch compatibility for watchOS 27
Apple has left quite a lot of older hardware behind with this latest update compared to last year. However, this makes plenty of sense, given that the new Siri AI features will require substantial processing power—and a line in the sand has to be drawn somewhere on watchOS support.
The Apple Watch Series 9 or later, the Apple Watch Ultra 2 or later, and the current-gen Apple Watch SE 3 will all support watchOS 27.
These Apple Watch models must also be paired with an Apple Intelligence-enabled iPhone nearby to process workloads—and that’s limited to iPhone 16 models (or later), iPhone 15 Pro, and iPhone 15 Pro Max.

How to update the Apple Watch
In truth, you shouldn’t need to look too hard to kickstart an Apple Watch update manually.
When a new one is available, your device will notify you, and from there you’ll be able to select ‘Tap Update Tonight’ within the notification—again, similar to your iPhone.
If both devices are on charge, the update will occur automatically.
Below, we’ll cover how to update the Apple Watch with or without your iPhone being present.
Apple Watch update with iPhone
- Open the Watch app on the iPhone, then tap the My Watch tab.
- Tap through to ‘General’, then ‘Software Update’.
- Enter your passcode (if you have one) and download the update.
- Wait for the progress wheel to complete on your Apple Watch.
- Keep the Apple Watch on the charger until the update is finished. Depending on the update’s size and your internet speed, this could take anywhere from a few minutes to an hour, so be patient.
Apple Watch update without iPhone
If your Apple Watch is running watchOS 6 or later and can use these steps to download it without the iPhone:
- Ensure your Apple Watch is connected to Wi-Fi.
- Find the Apple Watch’s Settings app.
- Tap ‘General’, then navigate to ‘Software Update’.
- If an update is available, tap ‘Install’ and follow the instructions.
Apple Watch won’t update? Try these steps
As mentioned, the Apple Watch sometimes won’t play ball when updating.
While you should generally follow Apple’s warnings about restarting your iPhone or Apple Watch during updates, sometimes your device may become stuck for hours in the same spot and require rescue.
If the update won’t download, or it’s having trouble porting over to the Apple Watch, try the following:
- Restart the Apple Watch by holding the side button until the power icon appears in the top-right corner. To turn it on again, press and hold the side button.
- Restart your paired iPhone. Hold the Sleep/Wake button until the red slider appears, then drag it. To turn your iPhone on again, reverse the step.
- From there, try to start the update again.
- If it doesn’t work, open the Watch app on the iPhone, go to General > Usage > Software Update, and delete the update file. Then, try downloading and installing the latest version of watchOS again.
