I am unable to pair my Apple 3 series watch

Hi balagowri,

Thanks for contacting Apple Support Communities!

We understand that you're unable to pair your Apple Watch with your iPhone, correct?

We do see that you've reviewed If you can't pair an Apple Watch with your iPhone - Apple Support already. Were you able to complete all the troubleshooting steps outlined in the article? If not, we would suggest that you work through the list of troubleshooting to help you to isolate this behavior further.

If you still can't pair your Apple Watch with your iPhone, just let us know what happens specifically when you attempt to do so. Be sure to include any specific details as well as the iOS version you're running on your iPhone and the watchOS version that's currently installed on your Apple Watch.

You can go to Settings > General > About to locate the version of your iPhone. On your Apple Watch, you can go to Settings > General > About to locate the watchOS version.

We hope this helps.

Cheers!
