Patek Philippe is my favorite brand by far. MBK have given us two great reps so far: the Nautilus and the exquisite Aquanaut which is extremely accurate. I will buy a gen some day.
Until then I can only hope the rep manufacturers will try and broaden their horizon, perhaps releasing more accurate and more reliable models like the Calatrava, Gondolo, or Ellipse.
PS; the watch you showed is of a genuine vintage Patek.
