Hands-On Review: Patek Philippe 5270 Perpetual Calendar Chronograph Blue


Patek Philippe has been associated with perpetual calendar chronographs for several decades now. Not only was Patek the first to unite both complications in a wristwatch (with the ref. 1518), but the brand even added, in some references, a split-seconds function or a minute repeater to this already prestigious package. At the 2014 Baselworld watch fair, Patek introduced a new color to its “entry-level” perpetual calendar chronograph, a white gold case with a blue dial. We at Monochrome Watches were quite fortunate to get our hands on this Patek Philippe (Ref. 5270).

It’s quite difficult to imagine, but the Patek Philippe 5270 is actually the simplest perpetual calendar chronograph of the collection; keep in mind that the two other references with these complications also feature a split-second (ref. 5204) or a minute repeater (ref. 5208). Clearly, though, the 5270 is not a simple watch. It is the latest edition in a long lineage that began with the reference 1518, the world’s first perpetual calendar chronograph, introduced in the middle of the 1940s. This extremely rare bird was produced for only 13 years, in 281 pieces, and features a movement based on a Valjoux ébauche but highly modified and adorned with the Geneva Seal. A few years later, during the early 1950s, Patek Philippe launched the Reference 2499, an improved edition of the perpetual calendar chronograph. Very similar in design, the 3970 and the 5970 came after that, with minor improvements and updated shapes. But in 2011, the 5270 added something very interesting to this classical model: an in-house movement. No more Valjoux or Lemania base here, but instead pure Patek Philippe.

Make no mistake about this Patek Philippe 5270. Even if it looks very similar to the previous reference, nothing is the same. The design, layout, movement, case, size… everything is new, but remains classical. Patek Philippe chose not to break the codes, but intended to improve and modernize an icon, when it introduced this reference in 2011 with a silver-white dial. Now, in 2014, Patek Philippe has come out with new dials, including the blue one we had the chance to handle for a few hours.

Before this new reference debuted, Patek Philippe would usually power its chronographs with a Lemania-based movement, Caliber 27-70. Even if that ébauche was deeply modified, both on the technical and finishing fronts, Patek at one point decided it couldn’t outsource anymore in an era in which the term “in-house” has gained so much importance. So the brand created a fully home-made movement, developed and manufactured in-house i.e., a manufacture movement. Patek Philippe Caliber CH 29-535 PS Q is a 32-mm manually wound engine that is impressive not only because of its complications, but also because of the quality of its finishing. As with every modern Patek Philippe watch, it is adorned with the Patek Philippe Seal. As we told you recently, the strictest of quality control standards are exerted in the manufacturing of every single component of the watch – the movement, the case, dial, hands, et al. – with rigorous standards applied to form, function, and accuracy.

A close look allows us to see the polished, beveled angles of the bridges and of the levers; the straight graining of the several elements that compose the chronograph; the polished screw heads and slots; several gold chatons; and Geneva stripes that continue from one bridge to another. The beauty of this movement also comes from its pleasantly deep layout, which permits viewing of all the gears’ and levers’ motions when activating the pushers. Some long-term Patek Philippe’s collectors may prefer the older Lemania’s bridges, but this one is actually very nice, too. The chronograph does (of course) use a column wheel with a vertical clutch for its engagement – the column wheel is, as is usual with Patek Philippe, hidden by a protective cap (that you can see on the photo above, in the lower part of the movement). The chronograph itself is very classical, with a bi-compax architecture displaying the measured seconds with a central hand, the minutes in a subdial at 3 o’clock and the running second in a subdial at 9 o’clock. Finally, it comes with the precise Gyromax balance wheel, using a free sprung architecture.

The movement is not the only interesting element here, and turning the watch to the dial side also shows complications. The perpetual calendar components are not visible through the sapphire caseback, as they are positioned on the top of the movement. However, the dial provides lots of information, with a clever and legible display. The day and month are indicated in two windows at 12 o’clock. The date and the moon-phase indicator are displayed in a third sub-dial at 6 o’clock. What is new compared to the previous reference (Ref. 5970) is the way it indicates the leap year and the day/night function. Previously, these two were positioned inside the chronograph’s counters at 3 and 9 o’clock and used hands to point out the information. Not the most practical and legible layout, as it was easy to get confused between the different hands. In the 5270, Patek Philippe has chosen to use two small apertures – at 4:30 for the leap year and at 7:30 for the day/night indicator. The dial gains increased legibility and aesthetic purity from that aesthetic decision.

Another change (like we said, every aspect has been changed or improved) is in the case, which has a diameter of 41 mm instead of 39 mm. It is slightly bigger, but remains in the classical and reasonable category (consider the Vacheron Constantin Patrimony Chronograph, which is 42 mm, and the A. Lange & Sohne Datograph Up/Down, which is 41 mm). It is made of 18k white gold and comes with an interesting, typically Patek shape – convex bezel, complicated lugs, and rectangular chronograph pushers. The case remains quite thin at 12.4 mm, and positions itself really well on the wrist. The overall appearance of the Patek Philippe 5270 is refined, complicated and elegant. The minor changes to the design give us a cleaner and more modern watch.

The last of the changes, and also new for 2014, is that blue color combination (both for the dial and the strap). Originally available in white gold with a white/silver dial, it is now possible to have the 5270 in blue, a less classical color and perhaps, therefore, easier to wear with a casual outfit as well. Even if blue is a cold color (especially when paired with a white-gold case), this new edition is, nonetheless, more appealing. The dial is not plain but slightly guillochéd, with a sunburst pattern, and thus gives off really nice reflections (that were unfortunately hard to capture during our photo shoot). The contrast with the white gold hands and applied indexes and the white inscriptions is excellent and allows for very good legibility. Furthermore, the blue remains serious enough for Patek’s lovers but adds an extra attractiveness to a very classical reference.

The Patek Philippe 5270G Perpetual Calendar Chronograph Blue is available in Patek Philippe boutiques, priced at about 135,000 euros.

  1. Honestly after a while I realized that complicated watches are more sensitive to be damaged by chance while even setting time and in general usually such a watches are purchased by rich people who are old enough to wear glasses. That means in normal everyday situations and on the street they don’t and to look on all these dials and get the date, day, or any is not an easy task and even with all dials you can’t see the time. Just for show… Simple watches always better, as even such a complicated watches can be damaged by a seller at a shop when you purchase it. As all of sellers try to show that they are very experienced and know all about watches and making mistakes while setting time and winding them, without having a look to manual. I had three watches damaged in such a way. Very top sellers… After that I ask always not even to touch watches when they are in a box from manufacturer. Better.

  2. I’m sorry to say, but this watch is a mess. The inclusion of the chronograph requires two dials that would normally be used for perpetual calendar. So as a result we get that dreadful two apertures. Tachymeter scale is superfluous, and is there simply to add to the price of the watch. Moonphase indicator is obscured more than 1/3rd of the time by a day-date indicator.

    Patek makes excellent watches, and I love their perpetual calendar models, but this watch seems to be done just for the sake of selling for a high price.
