Watch series 7 not pairing to the iPhone 16 Pro after iPhone got updated to latest iOS 27

My Apple Watch Series 7 (GPS + cellular) is not getting paired to my iPhone 16 Pro after my iPhone got updated to the latest version iOS 27. My watch got auto disconnected after my phone got updated and displaying update required in the watch. But while trying to update the watch, the watch application is crashing and throws an error mentioning cannot install the latest version in the watch.

Watch is having an update to latest version of WatchOS 26, but not able to complete the installation due to the error.

Already Tried resetting my watch and the reinstalling the Watch Application

Anyone had encountered similar issue or have any solution for the same?

This sounds like the Watch is getting stuck on the required watchOS update during pairing.

Since you’ve already reset the Watch and reinstalled the Watch app, try:

Keep the Watch on its charger with 50%+ battery.
Connect the iPhone to Wi-Fi and keep both devices close.
Check Watch app ->General -> Software Update and try again.

IOS27 does not support Apple Watch Series 8 or earlier. So your Series 7 is out of luck.
