I have the blue one, and it is worth it. the quality is better than your CN version. whether the price difference is worth it is really a personal call
bracelet edges, screws not stripping easily, fit and finish, gaps between links, etc.... are small details that to me, make it worth the $$ difference.
I have red somewhere that PP also make "custom combos" like Hublot does so a fantasy PPN is not really impossible.
Like Jeff, I wear mine with pride. on some weird occasions, I would try to slide my MBW 16610 under my sleeve, not because of fear of being called out, but I did not want to come across as a show-off. But not the PPN. Not a lot of people know it. But everyone who sees it always gaze at its beauty.
