Ref. 5270 – The Patek Philippe Classic Calendar Chronograph

After a long wait, Patek Philippe finally officially released Perpetual Calendar Chronograph Ref. 5270 which has been expected for long time and is equipped with the new CH 29-535 PS Q manual cochain movement calendar chronograph in 2011, writing a new and brilliant chapter for the glorious history series.

Equipped with a new generation of self-made calendar chronograph movement, the appearance of the 5270 watch also varies: the case diameter has increased to 41 mm. It is a classic structure made up with the watch ring, the watch circle and the case back. The lines generally continued from the 5970 generation, and the chronography button also adopted the rectangular design, which still exudes a feeling of elegance, and reveals a generous demeanor of contemporary chronometer.

In the aspect of the layout, the 5270 has still used the traditional features of Patek Philippe calendar Chronograph that is most widely respected in the past seventy years, that is to say, the week and month display window is located in the 12 o’clock position; the pointer date and moon phase display plate is arranged on the 6 o’clock position; small seconds display panel is located in the 9 o’clock position, 30 minute calculator is in the 3 o’clock position.

With a new self-made evolutionary movement, together with the exterior design and innovation of traditional classic elegance with 5270 will probably have an opportunity to enjoy the same glory with many other Patek Philippe Chronographs which have a long history, which not only attracts collectors’ pursuit and treasure, but also has extraordinary potential to be in the ranks of museum collections and creat value multiplication in the future.

Painstaking detail, from an aesthetic and technical point of view, combine with the use of the finest materials and the most advanced technologies. With its Classics collection, the brand reaffirms its position as the first watchmaker to offer luxury watches at a reasonable price, without any concession in terms of quality.

The latest addition to this collection, the Classic Moonphase Automatic watch, corresponds in every respect to this desire. In 2016, for the first time, three versions are proposed, all housed in a 40 mm case: one version in yellow gold-plated steel, one in stainless steel on a leather strap, and one in full in stainless steel.

This new model is powered by the automatic caliber FC-330 which displays the hours, minutes, seconds and date by a needle, an elaborate silver dial decorated with a Paris nails decoration, Roman numerals printed in black, and Breguet-style classic needles. The date is indicated in a counter and the moon phase in a very worked opening and positioned at 6 o’clock. On the back of the watch, the carefully decorated movement is admired through the transparent bottom. The bracelet is available in black, brown or blue leather with a full steel bracelet.

The commitment to make “luxury accessible” is part of the culture and DNA of Frédérique Constant, and this new timepiece is the perfect incarnation. An extremely worked watch, at a reasonable price.
