My Apple Watch and new iPhone won’t connect. When I am trying to pair them.

Hello Koneil67, 

Welcome to the Apple Support Communities. 

If the pairing process stopped unexpectedly, try resetting your Apple Watch first: 

1. Press and hold the Digital Crown. 
2. Tap Reset. 
3. Try to pair again. 

When pairing, please be sure that your iPhone has the latest version of iOS installed. You’ll allow want to be sure your iPhone has Bluetooth enabled and is connected to the internet. Please follow these instructions when you set up your Apple Watch. 

If you are still unable to pair, you may find that erasing and resetting your watch fully may help. This Apple Support article can help with that: If you can't pair an Apple Watch with your iPhone. 

Cheers!
