Patek Philippe Chronograph Perpetual Calendar 5271P

A parade of classic, complicated, and luxurious watches keep coming out of Patek Philippe. This latest release is a “Chronograph Perpetual Calendar“ gem-set with either rubies or sapphires. In essence the same quality case design of ref 5279, enhanced by the bling of precious stones and a new gradient dial.The 41 mm case is made of 950 platinum (one of the hardest precious metals to work on with robust qualities) with an overall polished finish. Despite all the complications packed inside, the case has a height of 12.7 mm. Mounted to the case is a platinum bezel adorned with 58 baguette-cut rubies or blue sapphires,which extend on to elegant two-tier lugs, for a total of 4.11 carats. On the flip-side is an interchangeable full back or sapphire exhibition caseback that allows a view into the inner workings of the mechanical movement. This caliber has 6 patents and the official press-release states: “Caliber CH 29-535 PS Q is distinguished by its traditional architecture, combined with six patented innovations relating to the chronograph, as well as by its exceptionally thin calendar mechanism.”It comes equipped with two rectangular push-pieces to operate the chronograph functions, while in between is a knurled screw-in setting crown embossed with the Calatrava cross. Plus very discreet pushers that allow adjusting the perpetual calendar features. Water-resistance can reach up to 30 meters (98 feet).Time is exhibited on a lacquered blue or red dial with 18k white gold applied hour index markers, followed by white printed tracks with minute and precision seconds. By doing so Patek opted to exclude the more commonly used tachymeter scale.The perpetual calendar display is laid out in a very effective and fluid way. On the upper-half of the dial are two framed windows with the day of the week and month. Just like all the other new Patek releases, these models also have a gradient dial. The center hue goes from the initial blue or red to a black-gradient tone, as it stretches out towards the rim of the dial.It features a tri-compax layout with three sub-dials: a 30-minute counter at 3 o’clock, a perpetual calendar with date at 6 o’clock, and sub-seconds at the 9 o’clock position. In the midst of the perpetual calendar we can also admire a detailed moon-phase, while to its side are two round apertures for the day/night indication and the leap-year cycle.
