Of course from "Plating" of the gold, we know that this is not authentic Patek Pilippe Watch. As genuine Patek Philippe does not have "Gold Plated Watch"!
We do not encourge to buy this kind of watch, but in fact the quality of the Calibre is good at least lasting for 20 years.
However the time keeping is bad and the plating is gone, looks awful, there is nothing Patek at all
