In merging these complications, Patek Philippe succeeded in implementing an even more important innovation.
Unlike other World Time minute repeaters that acoustically indicate home time even when their owners are located at the other end of the world, the Ref. 5531 always strikes local time, which means the hour displayed by the hands from the center in that time zone represented by the city aligned with the 12 o’clock position on the dial.
To accomplish this feat, Patek Philippe developed the new self-winding caliber R 27 HU calibre. A patent application has been filed for its unprecedented design. The 462-part movement is protected by an elegant rose-gold case with pierced lugs. Its caseband is hand-guilloched with Patek Philippe’s iconic hobnail pattern.
The dial is adorned with a cloisonné enamel motif, true to the tradition of Patek Philippe’s World Time watches. This little masterpiece of craftsmanship pays tribute to New York and depicts the Manhattan skyline by day and by night.
The new Ref. 5531 World Time Minute Repeater New York 2017 Special Edition consists of two 5-watch versions:
five with the “New York by Day” dial
and five with the “New York by Night” dial.
All watches have a sapphire-crystal case back with the engraved inscription “PATEK PHILIPPE NEW YORK 2017” as well as an interchangeable back in solid rose gold with the same engraving.
The 40,2 mm Patek Philippe World Time Minute Repeater Ref. 5531 New York 2017 Special Edition is sold for 561.341 USD each.
