Leading the charge of new releases, the Ref. 5531 ($561,341) is the epitome of all things Patek Philippe. To set this design apart from the rare few other world time minute repeaters in existence, Patek Philippe created the new self-winding caliber R 27 HU movement—an evolution of the self-winding minute repeater caliber R 27—which is capable of chiming the set local time rather than the home time, as other similar calibers do).
Patek continues to take great pride in the tonal quality of its minute repeaters. By separating the chiming gongs from the mainplate, engineers both amplified and clarified their sound output. A total of ten examples of the 5531 will be produced with cloisonné enamel dials displaying the New York city skyline (five “New York By Day” dials and five “New York By Night”).
