The Portuguese 7 Days perpetual calendar is a superb watch, indeed. The only thing I regret, like on the JLC siblings, is the 4 digit years window. It breaks the purity and class of the dial
But IMHO, you shouldn't consider my "fake" Lange as a fake because, except the dial (and the color of the case and the hands), everything comes from Lange, and it really looks like Lange (in fact, Lange could have done it!).
