Hi furqanmkhan1,
We're more than happy to do what we can so that you can re-pair your watch.
Which version of iOS is your iPhone using? You'll want to make sure that your iPhone is running 14.0.1. If not, go ahead and back up, then update.
After that, complete the following steps making sure to try and pair the watch after each one:
- When setting up the Apple Watch, choose to do it as new instead of from a backup.
- On the iPhone, forget the Wi-Fi network, then reconnect to it.
- On the iPhone, go to Settings > General > Date & Time and make sure "Set Automatically" is enabled, and the time zone is also correct.
- If you're using a VPN, temporarily disable or remove it and try again.
- On the iPhone, go to Settings > General > iPhone Storage and look for an Apple Watch Software Update. If you find one, delete it.
- Reset the Apple Watch using these steps: If you forgot your Apple Watch passcode
- Delete and reinstall the Watch app on the iPhone: How to delete apps on your iPhone, iPad, and iPod touch
- Disconnect any other Bluetooth devices from the iPhone. Don't unpair them.
- Try connecting the iPhone to a different Wi-Fi network.
- Go to Settings > General > Reset > Reset Network Settings. Make sure to save any network passwords, cellular settings and VPN/APN settings.
Let us know if that gets everything working for you. Have a good rest of your evening!
