Thank you for posting this and I am sorry that you have had to undergo this experience. I think the dealer must be delusional if he thought someone would part with $50m to buy a watch. A Grandmaster Chime is one of those watches that we do not expect to come up for sale but if it does, possibly by a reputable auction house. Enjoy your Pateks and I hope you will continue sharing photos of your amazing watch collection with us.
