DESCRIPTION

  • Oscillomax® in the real world: New Perpetual Calendar Ref. 5550P in a limited edition of 300  Patek Philippe Advanced Research timepieces.    

    The last three development steps in Silinvar® technology based on silicon were translated into Patek  Philippe Annual Calendar watches with the caliber 324 S IRM QA LU movement. These watches were  presented in limited editions of 100 to 300 pieces as “Patek Philippe Advanced Research” models, and  each edition sold out within months.    

    To fittingly present the Oscillomax® ensemble, Patek Philippe has now turned to the legendary self-  winding caliber 240 with a perpetual calendar; it aptly expresses the superiority of “Patek Philippe  Advanced Research” technology. It incorporates the following Silinvar® components: the patented  Patek Philippe Spiromax® balance spring, the patented Pulsomax® escapement, and the patented  GyromaxSi® balance. Patek Philippe has applied for a total of 17 patents in conjunction with the  Oscillomax® subassembly as a whole and also filed patent applications for its individual components.    

    New technology for a legendary movement     

    To present the advantages of Silinvar® technology, Patek Philippe chose a movement with a history of  over 30 years: the ultra-thin self-winding caliber 240. It is a choice that reflects the interaction of  tradition and innovation. It also shows that even an ingeniously designed movement like the 240, a  caliber that enjoys cult status among aficionados, still has plenty of potential. In the version with the  perpetual calendar (Q) that advances the date, day of week, and the moon-phase display on a daily  basis as well as the month and year, the movement must generate a considerable amount of energy.  This is an ideal point of departure to demonstrate the energy efficiency of the neu Oscillomax®  ensemble.     

    Caliber 240 Q Si: Two letters boost the power reserve from 48 to 70 hours    

    As always at Patek Philippe, the designation of the caliber 240 Q Si movement is self-explanatory. Q  stands for quantième perpétuel (French for perpetual calendar) and Si stands for silicon technology.  And this technology is responsible for a quantum leap in the classic movement. It accounts for a  significant increase of energy efficiency attributable to the innovative Oscillomax® subsystem,  particularly of the Pulsomax® escapement and of the GyromaxSi® balance. This gain is based on the  perceptibly lower mass of Silinvar® parts compared to conventional components, on the optimized  geometry of the lever and escape wheel, and on the much-improved aerodynamics and mass  distribution of the GyromaxSi® balance, to mention just some of the key reasons. Less energy  dissipated means greater efficiency as demonstrated by a power reserve increase of about 50%  without having necessitated any modifications of the mainspring, the frequency, or the moment of  inertia of the balance. The efficiency of the winding train has also been perceptibly improved. The  special-edition “Patek Philippe Advanced Research” perpetual calendar has a power reserve of up to  70 hours. This allows the watch to be set aside for an entire weekend without affecting its rate. Its owners will appreciate the fact that they can put the watch on again on Monday morning without having  to update the perpetual calendar displays.    

    The third element of the Oscillomax® ensemble is the patented Spiromax® balance spring made of  Silinvar®. Based on its superior material properties and its patented geometry with the Patek Philippe  terminal curve, integrated collet and integrated stud attachment, it delivers a significant improvement of  isochronism. It not only breathes symmetrically despite being flat, but is also antimagnetic, corrosion-resistant, and extremely insensitive to shocks. Additionally, with no trade-off in terms of isochronism,  the Spiromax® balance spring is three times flatter than a Breguet spring, making it ideal for ultra-thin  movements.    

    With the sum of all these characteristics of the individual Oscillomax® components, the caliber 240 Q Si  features a considerably improved power reserve combined with exceptional rate accuracy. It goes  without saying that the Ref. 5550P perpetual calendar of the “Patek Philippe Advanced Research”  series is subject to the same strict criteria defined by the Patek Philippe Seal that specify a maximum  daily rate deviation of -3 to +2 seconds per 24 hours for all mechanical watches with a diameter of  more than 20 mm.     

    Revolutionary technology with a classic personality    

    In a limited edition of 300 watches, the Ref. 5550P perpetual calendar is a superb manifestation of how  tradition and innovation go hand in hand within the scope of the “Patek Philippe Advanced Research”  design concept. It brings to the fore unique functional advantages such as the extended power  reserve, the high rate accuracy, true dependability, and convenient serviceability. The exterior  elements are equally sophisticated. The Calatrava-style case with the curved lugs and the rounded  bezel is crafted in-house from 950 platinum using traditional cold-forming techniques. As an exception,  because the correction push piece for the moon-phase display is located between the lugs at 6 o'clock,  the typical 0.02 ct. diamond that identifies Patek Philippe's exclusive platinum watches is positioned at  12 o'clock. The dial is timelessly contemporary and with many refined details suggests the avant-garde  technology hidden beneath it: a cool silvery gray face with a vertical satin finish, a crisp railway track  minute scale with applied luminous hour dots, straight obus hour markers in 18K rose gold, slender  leaf-shaped hour and minute hands with Superluminova coatings, the PATEK PHILIPPE GENEVE  signature, the ADVANCED RESEARCH inscription, and calendar scales in a modern sans-serif  typography style. It is an eminently legible, classically elegant face with novel accents that will inform  future generations of the horological quantum leap which took place in 2011.     

    The revolutionary escapement can be admired through the sapphire-crystal snap back. Over the  Oscillomax® subsystem, the back features a loupe that magnifies the innovative components. It affords  close-up views of the purple-blue shimmer of the Silinvar® material, the unusual shapes of the escape  wheel teeth and pallets of the Pulsomax® escapement, and the radically new geometry of the  GyromaxSi® balance with the attractive contrast between Silinvar® and 24K yellow gold. In compliance  with the Patek Philippe Seal, these components are embedded in a movement lavishly finished by  hand to the highest standards of watchmaking artistry, featuring manually executed decorations, gently  rounded and polished chamfers as well as gold-filled engravings.     

    The traditional finishing touch: the hand-stitched brown alligator strap fashioned from the finest parts of  the hide with large square scales is comfortably and reliably secured with a 950 platinum fold-over  clasp.
