The perpetual calendar chronograph is a combination of complications that ‘belongs’ to Patek Philippe. The 5270 continues a long tradition initiated in 1941. It was introduced in 2011 with an in-house movement as the successor of the 5970, itself an evolution of the 3970 (read our article about the different generations of the 5270 here). It is now available for the first time in the noblest of all metals, platinum. And it comes with a truly stunning salmon dial that – as often with salmon dials – is elegant, unostentatious but with that very special twist.
The reference 5270P is powered by the handwound calibre CH 29-535 PS Q. It combines a perpetual calendar with the column-wheel chronograph calibre launched in 2009. The chronograph mechanism is connected to the timekeeping gear train by a horizontal clutch and features jumping minutes for enhanced legibility. Operating at 28,800 vibrations per hour, it can store in between 55 to 65 hours of power reserve. The Gyromax balance is paired with a hairspring with a Breguet terminal curve. It comprises no fewer than 456 immaculately finished parts.
At 41mm, the 5270 is a rather large size among the Patek Philippe classic designs but it is superbly proportioned and comfortable on the wrist. It features slightly flared lugs, and rectangular pushers… The subtle shine of platinum adds its unmistakable class.
One of the defining elements of the new 5270p is its unapologetically elegant salmon dial with blackened gold applied baton numerals. It is highly legible and remarkably balanced in the characteristic Patek style.
Day of the weeks and month are indicated at 12 and the date at 6 o’clock together with the moon phase. Two small apertures show the day/night and leap-year indications. The smalls seconds subdial and 30-minute counter are just beneath the horizontal axis through the middle of the dial. A tachymeter scale sets the final touch. The hands (leaf-shaped for the hours and minutes) are also blackened gold and contrast beautifully.
The Patek Philippe 5270P is worn on a square-scale alligator strap secured with a fold-over clasp. It retails for EUR 168,340. For more information, you can visit www.patek.com.
