No need for a watch but in the UK Apple Pay rocks, I use on the train and in my local supermarket, coffee's etc so stupid we had to wait so long to get it!!
Oh yeah, plus it helps that Europe is much more advanced when it comes to contactless payments. Apple Pay is so sweet and it works 100% of the time for me. Just added another card as well, now I just wish I had more money so I can use it more hahah.
