Patek Philippe presents a new high-performance manually wound movement that measures and displays 1/10^th 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 movement was equipped with an additional chronograph mechanism exclusively dedicated to 1/10th of a second and the monopusher chronograph is equipped with two central hands, each driven by one of the mechanisms. 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. Last, 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).
