While visiting one of the Breitling Centres about a week ago I saw a template of a letter to ADs advising of an introduction of a new warranty card, just like a credit card. I guess I was not supposed to see it as it was quickly covered up

This card will have all the watch details stored on it and I believe it will be black in color.
I guess what you got is a version that comes when you get the watch serviced.
The 1,2,3 .... Years will be an advice when your watch is due for it's next service.
The warranty should still be 1 year.
