having read the full report made earlier about patek 5207, the design and its new instantaneous calendar function, most impressive. set aside price tag and all, i still think patek 5016 is more classic looking. the one thing i am not very sure of about the 5207, is the pattern engraving on the side, it kind of reminds me of Batman the Movie, those lines are a bit too contemporary for my taste.
who knows, may be in near future, all patek models with perpetual calendar function may apply this instantaneous movement. Possible ??
