Apple Watch SE 2 update fails pairing with iPhone 12 Pro Max

I am using an iPhone 12 Pro Max running iOS 26.5. When attempting to pair my Apple Watch SE 2, the iPhone forces a watchOS update during pairing. The update downloads successfully, but fails during the verification stage with the error:

“Unable to verify update — The watchOS update couldn’t be verified because you are not connected to the Internet.”

I have already tried:

different Wi-Fi networks
restarting both devices
resetting network settings
unpairing/re-pairing
disabling VPN/Private Relay

The important detail is that the same Apple Watch SE 2 pairs successfully with another iPhone XR running iOS 18.7, without requiring any watchOS update. The watch is currently on watchOS 11.6 (22U84).

This suggests a possible compatibility or verification issue related to iOS 26.5.

Did you try to update your watch directly and pair it again to your iOS 26 iPhone afterwards?

...

If your Apple Watch has watchOS 6 or later, you can install updates without your iPhone:

Make sure that your watch is connected to Wi-Fi.
On your watch, open the Settings app.
Tap General, then tap Software Update.
Tap Install if a software update is available, then follow the onscreen instructions.

If this does not work, have a look at the related Apple Support article about troubleshooting Internet connections while updating the Apple Watch:

Did you try to erase the watch completely after unpairing it from the iPhone XS?

Unpair and erase your Apple Watch - Apple Support

Also make sure, that no VPN or Firewall is blocking the contact to Apple Servers and the watch can connect to the same Wi-Fi as the iPhone.

I found more troubleshooting in the above mentioned Apple Watch Support article:

...

Try these steps:

Make sure that your Apple Watch is connecting properly to its charger.
Restart your Apple Watch.
Restart your paired iPhone.
Try again to update your Apple Watch.

If the update won't start:

Open the Apple Watch app on your iPhone.
Tap General, then tap Storage.
Delete the update file.
Try again to update your Apple Watch.

Learn what to do if you see 'Cannot Install Update' when updating Apple Watch or if your Apple Watch says you need more available storage to install a watchOS update.

Have you resolved your problem?

I have the same issue - iPhone 12 iOS 26.6 and Apple Watch SE 2 my wife changed her iPhone XS (failing digitizer) for my old (12) model but she can't get the watch to pair. Update downloads for hours, and afterwards it still fails.

Updating through the Watch is impossible 1) it fails to find an update (constant server error) 2) because to pair it to a new iPhone it resets to factory settings.
