Back in 1941, 70 years ago, Patek Philippe began adding perpetual calendar chronographs to its mass-produced chronograph product series, and since then they have become the brand’s most popular super-complex multi-function watch. This type of watch needs to integrate two extremely complicated devices, involving a lot of manual links. In order to ensure perfect manufacturing, only the most experienced professional watchmakers can complete it. This is one of the main reasons for the limited production of Patek Philippe complication watches. Similarly, the new Ref. 5270 watch brings together watch collectors’ expectations for all the features and performance of a future collection.

In terms of appearance, Ref. 5270 follows one of the most noble traditions of this type of watch: the day of the week and the month are displayed at 12 o’clock; the analog date and moon phase are displayed at 6 o’clock; the small seconds dial is located at At 9 o’clock; the 30-minute counter is at 3 o’clock. For 70 years, this has been the classic dial layout of Patek Philippe’s perpetual calendar chronograph. Of course, compared to similar models before, this perpetual calendar chronograph has some highlights of its own. The small seconds dial and 30-minute chronograph are positioned slightly below the horizontal centerline of the dial. There are two tiny circular display windows between the date display and the auxiliary dial, the day and night display window on the left and the leap year display window on the right. This new chronograph movement uses a star wheel control mechanism and a horizontal clutch wheel. It is hidden in the classic Patek Philippe dial. It is a boutique developed and manufactured by the Geneva Watchmaking Workshop.
Classic chronographs of the 21st century
The new manual winding chronograph movement CH 29-535 PS Q adds a perpetual calendar function. Compared with other traditional chronograph movements, it has more innovative and optimized functions. For example, although the engagement and disengagement of drive wheels, clutch wheels, and timing wheels are still performed in a traditional way, these gears use a recalculated patented sawtooth shape compared to conventional triangular gear teeth, which reduces wear, improves efficiency, and Prevent collision of tooth tips. In addition, the degree of gear engagement is not adjusted by the common eccentric wheel, but by a slightly eccentric polished star column dome cover. The polished dome cover of the stylus wheel can determine the position of the clutch lever at the outermost point very accurately. Other optimization features include a custom-built hammer between jewel bearings, a synchronous clutch stop lever and a pusher lever, and a minute timer cam with a notch to prevent the gear from suddenly decelerating excessively when it returns to zero. With these six patent-pending inventions, the new movement is definitely the most advanced of all traditional chronograph movements. At the same time, it is used to carry a perpetual calendar device-one of the most popular complication of Patek Philippe, and it is also perfect. In fact, the ephemeris device is of special significance to Patek Philippe’s watchmaking workshop in Geneva.
Classic gorgeous white gold case inherits fine traditions

Ref. 5270 case makes the sophisticated CH 29-535 PS Q movement and clear dial more noble and gorgeous. This 41-mm diameter case is much larger than its predecessor and is generous and decent. This case is made of 18K white gold and is made of traditional cold-molded technology. It has a typical three-piece structure. The solid platinum plate is placed in a high-precision mold, and the large tonnage heavy press is used for high-pressure die-casting. After cold forming, the watchmaker spends a lot of time processing the tube holes of the crown, chronograph button, adjustment button and strap bolt, and trimming, fine grinding and mirror polishing the case; after these After the process, the case with the concave bezel and elegant curved lugs is completed. The 18K white gold chronograph button has a rounded rectangular shape, which is very similar to the chronograph button of the first Patek Philippe perpetual calendar chronograph in the 1940s and 1950s. The slightly concave lugs on the sides are also inspired by these early models. The sapphire crystal see-through window on the screw-down case back can show some of the most attractive parts of the art of mechanical watchmaking: the large-scale Gyromax (Patek Philippe Gyromax series clocks) balance wheel and the main fork rod and gear of the timing device. The beautiful posture of these exquisite movement components in operation is amazing. With a hand-stitched matte black crocodile leather strap and 18K white gold folding clasp, the Ref. 5270 watch has a timeless classic light in modern craftsmanship.
