To me, Rolex has to be from AD. I personally came across a Rolex which is perfectly like an original but came out to be fake when sent to authorized repair center. Initially, even the professional thought that piece of Rolex is original. Its only when they see the movement , they realized its fake!!
You;ll only have piece of mind when the watches comes with complicated movement which is hard to duplicate like JLC. Thats my personal view.
