I cant pair my new iphone 6 w/my watch

Hi

To switch your Apple Watch to a new iPhone, follow the instructions here:

Switch your Apple Watch to a new iPhone - Apple Support

If you no longer have your old iPhone, but your watch remains paired to it, follow these steps:

- When viewing the time on your watch, go to the Home screen (via a single press on the Digital Crown) > Settings (cog icon) > General > Reset > Erase all Content and Settings.

You can then pair it to your replacement iPhone via the standard set up process (including the option to Restore from Backup, if your new iPhone was restored from a backup of your old one):
