Patek Philippe

PP could make a better slim automatic

 

According to Collectability, the cal. 240 base movement dates from 1977.


The power reserve looks even worse when we consider that the beat rate is just 21,600 vph. To compare, the 90s-developed slim GP cal. 3100 delivers a comparable power reserve at 28,800 vph.

Why there hasn't been a clean-sheet replacement in almost 50 years to one of the technical foundations of the company's mechanical watches?

As for the dial side module, yes, pushers are anachronistic too. There should have at least been a crown position to advance the day/date/moonphase together.

Collectability go on to say that PP wanted 'to compete with' thin quartz movements at that time in developing the 2.53 mm cal. 240. 

Which is merely Collectability's attempt to connote a history different from the fact that, just a few years later, Patek proudly unveiled the Calatrava ref. 3744 with a 2,50 mm thin in-house quartz movement. 

Here's the German-language advertisement:



And the machine translation:

PATEK PHILIPPE Quartz
More than a century separates these watches: the Patek Philippe quartz and the first Swiss wristwatch, created by Patek Philippe in 1868. It sealed the fate of the pocket watch. And it is still going on today. Because a Patek Philippe can be passed on from one generation to the next. Also the Patek Philippe quartz watch.

THE QUARTZ WATCH FROM PATEK PHILIPPE
Born from thirty years of electronics research

Shortly before 1950, watchmaking and electronics met. This is how a new technology emerged. Patek Philippe became its pioneer. The first fully electronic table clock, the first small-format quartz chronometer, the first electronic master clock... they all bore the Patek Philippe logo. Just like the first watch with a winding crown, which was invented by Adrien Philippe in 1842. At the same time, Patek Philippe's stylists developed ever more elegant and valuable models, while in the Patek Philippe ateliers each watch continued to be made as in the previous century: by hand. This combination of advanced technology and craftsmanship gave rise to the new Patek Philippe quartz watch.

ELECTRONICS AND PERFECTION
Patek Philippe's quartz movement is one of the thinnest in the world, measuring just 2.5 mm thick. True to its tradition of invention, Patek Philippe was not content with developing a quartz watch, but rather set itself the task of going one step further and achieving something unique in this field.

At Patek Philippe, however, the watchmakers spend just as much time on a quartz model as they do on a mechanical watch: several months. To polish, satinize and finish with all the care and patience a work that, at 2.5 mm high, is one of the thinnest in the world

Quartz, this tiny rod that vibrates 32,768 times per second, can be more or less accurate depending on how it was cut. That's why Patek Philippe tests every quartz with unrelenting rigor.

With the reserved nature of scientists, Patek Philippe engineers guarantee an accuracy of +1 minute per year. In reality, however, it is highly unlikely that a Patek Philippe quartz watch will exhibit a deviation of more than thirty seconds per year.

WATCHMAKING AND PERFECTION
Every part and every function of the Patek Philippe Quartz is subject to the strictest controls. The production is all the more reliable because the watches are checked after each operation using instruments specially developed by the Patek Philippe electronics department. The great accuracy of the quartz would be of little use if it were not transmitted to the hands by a mechanism of extreme precision. In Patek Philippe quartz watches, four out of five parts are mechanical - the drive, gear train and bridges are made entirely by hand. Like all parts of every Patek Philippe watch.
