I can’t pair my iPhone with my watch

What model of phone is it and what version of ios is it running?

What model of watch is it and what version of WatchOS is it running?.

What troubleshooting steps have you tried?.

What errror messages are you receiving?.

Has this watch ever been paired to another phone?(Very important).

If you can't pair an Apple Watch with your iPhone - Apple Support

Thank you! 😁
