Apple Watch won't pair with my iPhone

A couple more questions:

• By “new,” do you mean the iPhone 15? Which one?
• Did you remove the watch from your previous watch?

If you did not remove the watch from your previous iPhone, then these instructions copied from the link above your post should help.

BTW, if you have additional questions after following these directions, please provide as much detail as possible.

Erase Apple Watch without the paired iPhone

If you can't unpair Apple Watch because you don't have its paired iPhone, you can erase the watch.

When you erase Apple Watch instead of unpairing it, the watch is still protected by Activation Lock. Before you can pair Apple Watch again, enter the Apple ID and password that was used to set it up.

1. Open the Settings app on your watch, then tap General > Reset.
2. Tap Erase All Content and Settings, then tap again to confirm.
3. Wait for the watch to unpair.
4. After Apple Watch unpairs completely, you can pair again. You'll need the Apple ID and password that were used to set up the watch.

We need more information before we can help:

• Which iPhone do you have?
• What is its iOS?
• What happens when you try to pair? Is there an error message? If so, what does it say?

I have a new phone and don’t have my old phone and it won’t let my watch pair to the new phone
