For my personal taste, the yellow gold 514 with Breguet numerals and the rose gold 5101 really stand out. I would love to see one of these for real.
On the secondary market, the P is indeed a little less unaffordable than the rose gold. And the J seems nowhere to be found.
Hopefully, Patek will create another, new and different, statement caliber and design in the future.
Best, Emmanuel
