Japanese word for "fake"

OKOK, so when I was in Japan, I was trying to explain that the rolex on my wrist was a fake. Like the kind that you can buy on the streets in New York. I could not for the life of me think of how to explain it. What is a word for "Fake" as in a "knock-off product"

Japan and the UK seem to be active in hunting for fakes. Of course a fake Rolex is more difficult to spot than a fake Luis Vuitton bag but if you get stopped in customs and they spot it, they will confiscate it and you get fined.
At least according to a BBC programme some time ago. ^_^;;

I think that that doesn't happen much in America, because then they would have to stop all of New York from travelling...

^^^^^^^^^^^^^^^^
i was thinking the same thing lol
