Change Apple ID associted with Apple Watch
Hello. When I first paired my Apple Watch to my iPhone it grabbed the e-mail address associated with my iCloud account and not the one associated with the iTunes/App Store. How can I change the Apple ID being used by the watch. I have a iPhone 5S and want to set up Apple Pay, but I don't want to use the e-mail account it had defaulted to and can't find any way to change it.
Thanks.
