In the early years of 3970/5020 the G and P had yellow/blue moon discs, then Patek ( IMHO unfortunately) went with the more modern look of black/silver. So it surprised and delighted me that the 3rd and last dial version of5496P went back to yellow./ blue. I love 5496P but I feel like I am in a small minority in that assessment. Anyway for a third watch to compare … Best, Patekova
