My watch will not pair with my new 15

Hi janeka129,

Thanks for contacting Apple Support Communities!

We understand that your Apple Watch won't connect to your iPhone.

Have you had your Apple Watch and iPhone paired before?

Also, check out this resource which explains how to troubleshoot your Apple Watch connection with your iPhone: If your Apple Watch isn't connected or paired with your iPhone - Apple Support

"Check your Apple Watch connection

If you don't get notifications, messages, or calls on your Apple Watch, your Apple Watch and iPhone might not be connected. When your devices disconnect, the red iPhone icon  or the red X icon  appears on your watch face. You can also check your connection in Control Center. When your Apple Watch connects again, the green iPhone icon  appears.

First, bring your Apple Watch and paired iPhone close together. If you still see that the devices are disconnected and need help, try the steps below. After each step, see if your devices can connect."

We hope this helps.

Cheers!
