The House of Plan-les-Outes is launching for the first time a wrist chronograph capable of measuring the tenth of a chronograph second (Ref. 5470P-001), thanks to the use of a hand-wound mechanical movement equipped with two independent chronograph mechanisms. At the centre of the dial are two chronograph hands, one in red (which makes one revolution in 12 seconds, running through 12 sectors divided into tenths), dedicated to reading tenths of a second, and the other for chronograph seconds. The two additional counters are dedicated to reading instantaneous chronograph minutes (at 3 o'clock) and continuous seconds (at 9 o'clock).
The calibre that Patek Philippe engineers started from for this new project is the CH 29-535-PS, from 2009. The new calibre, named CH 29-535 PS 1/10 and which has a frequency of 36,000 vibrations per hour instead of 28,800 (in order to be able to measure the tenth of a second) is combined with a total of 31 patents, 7 of which are totally new. It is the first high-frequency movement signed Patek Philippe. As mentioned, the company's designers decided to equip the new calibre CH 29-535 PS 1/10 with two independent chronograph mechanisms, one dedicated to instantaneous chronograph seconds and minutes and the other to measuring and displaying tenths of a second.
The CH 29-535 PS 1/10 calibre (diameter 29.6 mm, thickness 6.96 mm, 396 components, 38 jewels, power reserve of at least 48 hours), a single-pusher chronograph, is visible through the sapphire crystal porthole positioned on the caseback (the company also supplies a second solid caseback) and is housed in a 41 mm platinum case 13.68 thick. Of particular note is the presence of the Oscillomax regulating organ, developed by the "Patek Philippe Advanced Research" technical department and used for the first time in a current collection since the limited series launch of the "Patek Philippe Advanced Research Ref. 5550P" perpetual calendar (2011).
