EDIT: I found the problem. My region format was not set to United States. I had to go into the Apple Watch app on my iPhone 5S > General > Language & Region > Region > United States. Once I set that, the Passbook option changed to say Passbook & Apple Pay. So it does work! Just make sure you have the correct region! Received my 42 Blue Sport Watch this morning. Delighted with it so far, but just still trying to get used to all the new options, apps and notifications etc. I have an iPhone 5S, so I was eager to try setup Apple Pay on the Watch, but I've been unable to figure it out. On the Apple site: https://www.apple.com/watch/apple-pay/ It says the following: "Setup is simple. To set up your credit and debit cards on Apple Watch, simply open the Apple Watch app on your iPhone and select the "Passbook & Apple Pay" option. Tap "Add a Credit or Debit Card."" However in the Apple Watch app on my 5S there is no "Passbook & Apple Pay" option, I only see "Passbook" and when I go into it there's no mention of Apple Pay. (You can see what the screen says in the attached image) Has anyone else with a 5/5C/5S been able to setup Apple Pay?
