Few models command as much attention as Patek Philippe world time and minute repeating timepieces. Both complications are indissolubly linked with the manufacturer; the world time is as iconic in its modern incarnations as it is in its ultracollectible vintage ones; on the other hand, the company holds in such high regards their minute repeating watches that every single one of them is reportedly tested by the company’s president and owner - Mr. Stern - before leaving the factory.
It is no surprise, then, that when in 2017 Patek Philippe unveiled a timepiece reuniting the two complications - and adorned it with an exquisite enamel dial - the collective gasp of the collectors’ community was most probably heard in nearby star systems.
Reference 5531 immediately rose to the top of horological aficionados’ hit lists worldwide - while the output of this outstanding work of art is and remains extremely limited, estimated in a few examples per year: true “unobtanium” for even the deepest pockets in the market, with the few lucky recipients of the watch guarding their pieces with extreme tenacity.
The model was technically launched at the Patek Philippe New York Grand exhibition, but in fact on that occasion only 10 examples - 5 sporting the NY skyline during daytime on the dial, 5 sporting the skyline at sunset - were made. The model was introduced in the official collection only the following year, featuring an enamel dial representing the Lavaux vineyard terraces on the shores of Lake Geneva. Thus, it in fact follows the tradition of vintage world timepieces - which at times feature a cloisonné dial with various geographical maps. Albeit it is customarily defined as “cloisonné”, fact this dial is a highly unusual and complex hybrid. Gold wires are used to define compartments (cloisons) then filled with enamel powder as it always happens with cloisonné dials. However, the compartments are not simply filled with monochrome enamel. They are furthermore decorated in the technique of miniature enamel dials; this is most obvious when examining the surface of the lake: minuscule highlights of blue and yellow render the impression of ripples on the surface of the lake and of the reflection of the sky. Such enormously complex dial design is without a doubt one of the reasons behind the scarcity of the timepiece.
The other reason, of course, is the movement. When Patek Philippe decided to launch a world time minute repeater, they knew very well that they were “toying” with their two most iconic complications. Thus the final result truly had to be exceptional, both under an aesthetic point of view and under a mechanical point of view as well. The result of this effort is the innovative cal. R27HU. While world time minute repeaters have been realised before, never before a world time piece has been able to chime the local time, being instead immutably set on the home time. Ref 5531 indeed synchs its chiming with the local time, which can be adjusted when travelling by pressing the pusher at 2 o’clock. Next to this landmark innovation, many other subtle details are introduced, such as security systems to avoid damaging the movement if trying to change timezone while the repeater is engaged.
While any example of reference 5531 can be rightfully considered as a crown jewel of any watch collection, the present example pushes the boundaries of collectability even further. Offered complete of all its original accessories, it is even factory single sealed, further adding to its collectibility. Considering how difficult - some would say near-impossible - is to obtain this watch from Patek, and compounding to that the even higher difficulty of obtaining a sealed example, present factory fresh timepiece can be deemed as one of the pinnacles of collectability when it comes to modern timepieces.
The present watch is the second example of its kind (on strap) to ever come on the market, underscoring its absolute rarity.
