I need help pairing my apple watch to my new phone. My last phone screen cracked so I didn’t have a chance to unpair it

Here are two ways to unpair your watch if you no longer have the paired iPhone:

• See the 'How to erase your Apple Watch if you don't have your iPhone' section of:

Unpair and erase your Apple Watch - Apple Support

• With a web browser, go to: https://www.iCloud.com and sign in with your Apple ID. Open Find My iPhone and select All Devices (at the top). Then click your Apple Watch, select 'Erase Apple Watch', and select Next until the device is erased. Finally click "X" next to remove your Apple Watch.

On your phone go to settings and click your apple id account at the very top, you should see your watch within here. Remove it from your account and then the watch should prompt you to pair
