Patek Philippe Introduces Technical Launch Ref. 5470P

Patek Philippe unveils its first wrist chronograph for tenths-of-a-second short-time measurements with a new, very precise high-performance movement.



Patek Philippe is delighting chronograph connoisseurs and enthusiasts with a new high-performance manually wound movement that measures and displays 1/10th of a second – while maintaining this high degree of accuracy throughout the entire timekeeping process.

To meet this mechanical challenge, the Manufacture used the CH 29-535 PS caliber, the first Patek Philippe classically built chronograph movement entirely designed and produced in its workshops and accompanied by six patents (2009). The frequency was increased from 4 to 5 Hz (36,000 vibrations per hour, or ten steps per second) and the movement was equipped with an additional chronograph mechanism exclusively dedicated to 1/10th of a second.

In order to guarantee simple and fast reading of measured times, the movement developers devised a patented system of concentric seconds and fractions of a second indications. The monopusher chronograph is equipped with two central hands, each driven by one of the mechanisms. One hand (with a one-minute rotation) allows the seconds to be read in the traditional way; while the other hand revolves around the dial in 12 seconds, covering 12 sectors, each subdivided into ten sections corresponding to tenths of a second.

To meet the triple objective of efficiency, reliability and precision, the Manufacture has integrated – for the first time in the current collection – its high-tech Oscillomax® regulating organ developed by the Patek Philippe technical department responsible for the innovations featured in the 2011 “Advanced Research” series (17 patents). Seven additional patented innovations developed for this new 29-535 PS 1/10 caliber also contribute to reducing energy consumption, protecting the movement against shocks and avoiding the risk of breakage in case of mishandling.

This new small-series Grand Complication model is housed in a platinum case with hollowed and satin-brushed flanks. Its sporty touch is enhanced by details such as the 1/10th of a second hand in red-lacquered Silinvar® and the calfskin leather strap with navy blue embossed fabric pattern and contrasting red stitching.
