No two Rare Handcraft dials are of course equal, almost by definition, which makes them even more personal and special to a collector's eyes! ;-)
You have such a nice collection that it would make sense for you to request Patek an out-of-catalog Rare Handcraft for yourself

I don't have a timeline yet, but I hope we can announce the 2022 RH models later next month, with the beginning of Watches & Wonders. On that day, if you see something that you like, you could ask your AD to put in an application for you....every year, a few dozen people around the world get lucky, and given your sincere passion, I hope you can be one of them! ;-)
Cheers from my "School of Fish" (ref. 5177G-028, from the 2021 Collection) along with a good Amaro
