Apple Watch Series 7 unusable — required update fails during pairing

My Apple Watch Series 7 is stuck during setup and is currently unusable because the required watchOS update fails.

The watch has been unpaired and erased. When I try to pair it again, the Watch app requires a software update before setup can continue. It briefly shows “Verifying,” then displays this error:

“Unable to Install Update. An error occurred installing the latest version of watchOS on your Apple Watch.”

Device details:

  • Apple Watch Series 7 — the device information screen reports watchOS 26.0.2.
  • iPhone 15 Pro Max running iOS 27.0.
  • I also tried pairing with my wife’s iPhone 14, but it fails at exactly the same stage.
  • Both attempts were on our home Wi-Fi. I do not use a VPN.

Because the watch is erased and setup cannot finish, I cannot access its Settings or delete the update through the Watch app’s storage settings. Skipping the update exits setup instead of allowing me to use the watch.

Has anyone successfully resolved this? Is there a way to recover or update the watch while it is stuck in pairing mode, or does Apple need to restore its software through a service centre?

That is an older watch that is out of warranty. Is this a new problem for a watch that previously worked? Or is this a watch you recently purchased used? I would suggest you make an appointment at the Genius Bar of your local Apple Store. They can try to run diagnostics and let you know the price to repair it, assuming it is repairable.

Thank you for the additional information. Hopefully one of our more expert volunteers will reply with help. If not, you can try the Genius Bar, as I originally suggested.

Thank you for your reply. These are our own watches, not a recent second-hand purchase. I originally used them, and then passed them on to my wife. They were working before this issue.

After my wife updated her iPhone to the new iOS version, the watch stopped receiving notifications and said it needed a watchOS update. However, the update kept failing.

To try to fix this, I unpaired and erased the watch. Now we are stuck: pairing requires an update, but the update fails during verification, so setup cannot be completed and the watch is unusable.

The watch reports watchOS 26.0.2. I have tried pairing it with both my wife’s iPhone 14 and my iPhone 15 Pro Max running iOS 27.0, with the same result.

I understand that the watch is out of warranty, but this started after the iPhone software update. Is there any way to restore or update the watch’s software without completing the pairing process?
