How can I set up my new Apple Watch series 8

Hello punam83,

Welcome to Apple Support Communities, and congratulations on your new Apple Watch. Which iPhone model, and iOS version are you trying to pair your Apple Watch with? You can find this information on your iPhone under: Settings > General > About.

It looks like you're at step 3 in the process of setting up your Apple Watch where you need to pair it with your iPhone as described here:

3- Hold your iPhone over the animation

Center the watch face in the viewfinder on your iPhone. Wait for a message to say that your Apple Watch is paired.

If you can't use the camera, or the pairing animation doesn't appear or your iPhone can't read it, tap Pair Manually, then follow the prompts.

Kind regards.
