Patek Philippe 5470P 1/10th Second Monopusher Chronograph

Patek Philippe first developed a tenth-of-a-second chronograph back in the 1930’s on a pocket watch, which can still be seen at their museum. Now over 80 years later, they have crafted the new “Patek Philippe 5470P 1/10th Second Monopusher Chronograph” as the first wrist chronograph that can measure and display tenths of a second. The 41mm case is made of 950 platinum with brushed and polished accents. Mounted to the case is a concave bezel with a polished finish, while the recessed casebands have a brushed interior.On the flip-side we’ve been given the option of an interchangeable solid or sapphire exhibition caseback that allows a view into the inner workings of the mechanical movement. This caliber has 17 patents and as the press-release says: “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 indication.”Another subtle but worth mentioning detail comes in the form of a brilliant-cut diamond placed between the slim downturned lugs at 6 o’clock.It comes equipped with knurled setting-crown embossed with the Calatrava cross, plus a rectangular push-piece (monopusher) just above it to operate the start-stop-reset functions. Water-resistance can reach up to 30 meters (98 feet).Time is exhibited on a brass-based lacquered blue dial with applied Breguet numerals in 18k white gold, followed by minute pearl markers, and a railroad-motif track of white and red printed markers.There are two snailed sub-dials for each independent chronograph mechanism: a sub-seconds and 30-minute counter at 3 o’clock, plus another exclusively for measuring stopped tenths of a second. That’s why this watch comes with two sweep chronograph hands. The silver hand can do a full revolution per 12 seconds (five times faster than a regular chrono hand) and sweep across 12 sectors subdivided into tenths.The central 18k white gold leaf-shaped central hands and pearl markers have all been fitted with a luminescent coating, for an enhanced legibility. There is also a tenths-of-a-second chronograph hand in red lacquered Silinvar.
