Patek Philippe copy presents its first wrist chronograph capable of measuring short tenths of a second, equipped with a new, very precise high-performance movement.

If Patek Philippe is known for its elegant, well-crafted watches, the brand also has strong expertise in research and development, mainly in its advanced research program. Today, just after Watches and Wonders, Patek Philippe presents a new and impressive chronograph, the first to focus on the areas of short-term measurement and precision. We’re talking about a hand-wound movement here, with two separate chronograph mechanisms and sweeping hands, with a high frequency and a tenth of a second display. And holds no less than 31 patents (7 of which are unique to this watch)… The new Patek Philippe 5470P-001 1/10 Second Monopusher Chronograph has a sporty and innovative design and mechanical aspects specialty.

Chronographs are definitely something Patek Philippe has been making since 1856. Around 1930-31, the brand developed the first pocket watch with a tenth of a second chronograph, which can now be seen in museums. Today, the brand unveils the Patek Philippe 5470P, its first wrist chronograph movement to measure and display tenths of a second. The basis of this impressive new movement is the famous movement CH 29-535 PS, launched in 2009 and can be found, for example, in the superb hand-wound chronograph 5172 or its predecessor, the 5170. This movement is now called the basis of all Patek Philippe hand-wound chronographs, with or without additional complications.

If the architecture remains traditional – manual winding, column wheel control, horizontal wheel clutch – the new movement (Calibre CH 29-535 PS 1/10) has been deeply reworked, first increasing the frequency, moving from 4Hz (28,800vph) to the present It’s 5Hz (36,000vph), which is necessary to measure a tenth of a second – a Patek Philippe chronograph debut. But the classic sweep second hand and 5hz are not enough to display the required precision. “The dial of the watch doesn’t provide enough space for the scale, which is very compact, with a tenth of a second scale,” explains the brand. To address this legibility problem, the Patek Philippe 5470P incorporates two separate timing mechanisms: one for the seconds and instantaneous 30-minute counters, and another dedicated to measuring and displaying the tenth of a second paused.

Patek Philippe’s watchmakers thus conceived a patented system that would concentrically display the measured seconds and the fractions of the seconds. The 5470P is equipped with two swept-frequency chronograph hands, each driven by an independent mechanism. The silver hand, which makes one revolution per minute, traditionally shows the number of seconds stopped. The other hand, painted in red, makes one revolution every 12 seconds, five times faster than a normal chronograph hand, sweeping across 12 sectors subdivided into tenths. Therefore, the display becomes clearer and more precise. “In this way, the user can immediately read the elapsed seconds guided by the pearl markers, and then read the number of elapsed tenths of a second from the last red marker on the outer railway track scale.” copy luxury watches

The white 5Hz frequency improves accuracy and allows a 1/10 display, it also requires more power – especially with the extra central and fast hands. The single mainspring has been redesigned for greater efficiency to maintain the spring’s amplitude as much as possible and ensure optimized rate stability. In addition, the diameter of the barrel arbor was reduced and the number of mainspring coils increased. Patented notches reduce the tension of the sliding straps during winding. The result is a comfortable 48-hour power reserve.

To make the 5hz frequency possible and reliable, Patek Philippe relies on all the innovations of the Advanced Research Department, including the Oscillomax ensemble. The mechanism uses a Spiromax hairspring, a Pulsomax escapement and a Gyromax balance wheel, all elements made of Silinvar (silicon-based material). This is the first time Patek Philippe has added an Oscillomax ensemble to its current collection since the introduction of the Perpetual Calendar 5550P. In addition, the Patek Philippe 5470P 1/10th of a second monopusher chronograph features several innovations in the fluidity of the display (thanks to a novel two-part drive wheel) and shock absorbers. Connected to a dedicated clutch, the structure of the 1/10th second drive wheel is a two-part structure with a rigid plate and a flexible plate superimposed. Equipped with an elastic backlash compensation system to ensure the correct meshing of the gears, thus preventing the 1/10 second hand from being stuck. Two patented anti-vibration mechanisms have been developed. The first mechanism consists of a hook principle to hold the lever in its clutch-engaged position. It engages with a hook that has been added to the column wheel cover. 1/10 of the second pinion has micro teeth. Its connection to the clutch wheel is secured by preload and two patented pendulum dampers and their springs.

The Calibre CH 29-535 PS 1/10 housed in the Patek Philippe 5470P case is also equipped with a new single-button construction. Two button operation start-stop-reset function.

The Patek Philippe 5470P has a decidedly modern and sporty look. The 41mm case, made of 950 platinum, is reminiscent of the split-seconds watch 5370P, introduced in 2015, with its concave bezel and case sides slightly recessed and satin-finished, transitioning to the lugs and their lobes shape. As platinum, a flawless brilliant-cut diamond sits between the lugs at 6 o’clock. The watch comes on a blue calfskin strap with an embossed fabric pattern and striking red stitching.

The dial also has a modern and sporty style with a dark blue and matte blue lacquer finish. It features the classic applied Breguet numerals and pearl minute track in a double compound layout and small seconds. The chronograph seconds are indicated by sandblasted and rhodium-plated steel hands, the tenths of a second are shown by lightweight Silinvar and lacquered red slender hands. The silicon hand needs to be patented for two solutions. Traditionally, the hands are mounted on the movement by hand-made brass tubes. Patek Philippe had to develop a process to combine this brass tube with silicon hands. Hands can be painted bright red thanks to a novel surface primer process.
