Patek Philippe 5470P-001 1/10 Second Monopusher Chronograph
The Patek Philippe 5470P-001 1/10-Second Monopusher Chronograph is housed in a beautiful 41mm platinum case. Featuring a blue dial, it can measure elapsed time to the nearest 1/10th of a second using dedicated red hands and an accompanying track. It's simple, it's exquisite. However, as Angus Davies explains, the work of Patek Philippe's Advanced Research Department played an important role in the creation of this model, which proved particularly interesting.

Despite having a rich history dating back to the 19th century and adhering to many traditional practices dating back generations, Patek Philippe has never shied away from progress. The "Patek Philippe Advanced Research" department is at the forefront of new technologies. In 2017 it designed the Ref 5650G, the Advanced Research Aquanaut Travel Time equipped with an "optimized Spiromax hairspring made of Silinvar"; with patented terminal curves and inner bosses, an innovation that ensures a higher mechanical watch Accuracy. Additionally, the movement features "a compliant (flexible) mechanism made of traditional horological steel for setting the second time zone of the time zone watch."
In December 2021, the Geneva brand presents the Ref 5750P, the Advanced Research Fortissimo. The minute repeater features a "patented sound amplification and diffusion system consisting of a flexible suspended tone bar, a sapphire crystal vibrating element and a titanium ring with four openings". While the minute repeater is a centuries-old complication, Patek Philippe Advanced Research has chosen to challenge convention and pursue progress for the benefit of its customers.
These are just two examples of the work being carried out by Patek Philippe's Advanced Research Department, but this team of experts is constantly pushing the limits of performance in the esoteric world of watchmaking. The department was established in 2005 and has done an impressive job. Most notably, it has been a pioneer in developing applications for Silinvar, a material derived from silicon (silicon in French).
Now, the men in white coats working in Patek Philippe's Advanced Research Department have played a major role in creating the new model Patek Philippe 5470P. The watch consists of two separate chronograph devices, one connected to the central chronograph seconds hand, which rotates 360° per minute, and the other, which drives the vermilion hands, which make one revolution every 12 seconds. Each hand works with its own dedicated track, with red hands wrapping around the dial and its second track showing the time to the nearest ⅒ second.
The frequency of the balance is 5Hz. That's not groundbreaking in itself, in fact, the Zenith El Primero, released in 1969, had the same rhythm. What makes the Patek Philippe 5470P special, however, is its ability to display elapsed cycles in a highly understandable format, accurate to ⅒ seconds.replica watches price
The problem with high frequency movements is that they consume a lot of energy, consume a lot of lubricant and can wear excessively. However, these problems have been solved with the introduction of the lightweight, frictionless material Silinvar. Furthermore, by addressing the above issues, high frequency motion provides excellent rate stability and is less susceptible to positional effects.
Read the spec sheet for the Patek Philippe 5470P-001 and you'll be struck by the amount of terminology used, many of which are marked with a ® symbol. Oscillomax, Silinvar, Spiromax, Silinvar and Gyromax are all mentioned in the brand's press release. Likewise, seven patents pertain to the new model's movement, the CH 29-535 PS ⅒ movement. It's easy to be fooled by even the most nerdy enthusiasts, but rest assured, every registered trademark and patent means progress that everyone can appreciate.
Quite simply, Patek Philippe may be a legacy company with its own museum and impressive catalog of hits, but the advanced research department is always looking forward to delivering superior performance to future owners, which in my opinion is a good thing.
Patek Philippe presents its first wristwatch with a very precise high-performance movement capable of measuring short periods of tenths of a second.
The manufacturer reaffirms its competence and innovative spirit in the field of short-duration measurement: it presents a hand-wound movement with two independent chronograph mechanisms and sweeping hands. One of them represents a tenth of a second—precisely and very clearly. This high-tech high-frequency movement (5 Hz) has 31 patents, 7 of which are new for the new mechanism, and features a platinum case, blue dial and red accents. Its sporty design emphasizes high-tech and performance-oriented aspects. With this low-volume one-tenth of a second monopusher chronograph - which is as difficult to make as a tourbillon, minute repeater or split-seconds chronograph - Patek Philippe impresses connoisseurs with a new fascination And fans rejoice. complex field.
At Patek Philippe, chronographs have a rich and long tradition. Since 1856, the manufacturer has distinguished itself for its outstanding assets, with its pocket chronographs with or without rattrapante, often combined with other complications such as the perpetual calendar or the minute repeater. Around 1930-1931, the manufacturer even developed a pocket watch with a tenth of a second chronograph. Today, it can be admired in the Patek Philippe Museum (Inv. P-340). As early as 1923, Patek Philippe was commissioned to produce the first split-seconds chronograph. From 1927, the first wrist chronographs with or without rattrapantes in regular production followed this piece, including the legendary Ref. 130 from 1934 to the early 1960s.replica Bovet Virtuoso Watch
The first decades of the third millennium were particularly prolific in the field of short-term measurements. Since 2005, Patek Philippe has developed a range of chronograph movements with or without additional complications (rapt-sweep, minute repeater, perpetual calendar, annual calendar, world time), all in the manufacturer's workmanship. Designed and produced in the workshop. These chronograph movements feature several innovations and patented optimizations. Today, they are embedded in a regular collection with more than 20 different styles for women and men.
Condensation of Mechanical Achievement
To further push the boundaries of mechanical timepieces and please high-tech watch lovers, Patek Philippe decided to develop its first wrist chronograph movement capable of measuring and displaying tenths of a second. To do this, the engineers used an in-house movement developed over the past two decades. It is the CH 29-535 PS calibre introduced in 2009; it reflects the traditional architecture (manual winding, column wheel control, horizontal wheel clutch), enhanced by six patented innovations, complemented by a calibre with two sweeps Split-second version with chronograph hand (CHR 29-535 PS).
The first task is to increase the frequency of exercise. The CH 29-535 PS movement has a frequency of 4 Hz (28,800 semi-oscillations per hour, making the movement and chronograph hands beat 8 times per second), and the CH 29-535 PS movement can only measure one-eighth of a second. In contrast, the new movement CH 29-535 PS 1/10 beats at a frequency of 5 Hz (36,000 semi-oscillations per hour, 10 beats per second), so it can measure a tenth of a second. It was the debut of a Patek Philippe chronograph, but it also required more power.
However, just sweeping the seconds hand and a frequency of 5 Hz is not enough to display a tenth of a second with the required accuracy. The dial of the watch does not provide enough space for the scales, which are very compact, with only tenths of a second scale. Therefore, the designers decided to provide the CH 29-535 PS 1/10 movement with two separate timing mechanisms: one for the seconds hand and the instantaneous 30-minute counter, and another dedicated to measuring and displaying tenths of a second the pause.
Patented concentric display
With this decision, Patek Philippe opted for good legibility. In keeping with the manufacturer's customer-centric creation philosophy, the chronograph's tenths of seconds, seconds and minutes are guaranteed to be ideally organized, fast and reliably readable.
So engineers conceived a patented system that concentrically displays the measured seconds and fractions of seconds. The watch is equipped with two swept-frequency chronograph hands, each driven by an independent mechanism. The hand, which makes one revolution per minute, traditionally shows the number of seconds stopped. The other hand (painted red in the new Ref. 5470P-001) makes one revolution every 12 seconds, i.e. five times faster than a normal chronograph hand, and sweeps 12 sectors subdivided into tenths. This way, the user can instantly read the elapsed seconds guided by the pearl markers, and then read the elapsed tenths of a second from the last red marker on the outer railway track scale.Online replica watch
Given such simplicity of use, the core of the patented system is a veritable treasure trove of ingenious solutions in motion, but unseen. As usual, Patek Philippe raised the bar and specified that the new movement should meet ambitious demands in every respect. Not only does the watch have to be able to measure and display tenths of a second, it also has to maintain that precision during the 30-minute run of the chronograph. In addition, the CH 29-535 PS 1/10 movement had to be made as compact as possible, while maintaining the diameter of the base movement (29.6mm) and allowing only a slight increase in height (from 5.35mm to 6.96mm) – despite the two chronographs Mechanism, a total of 396 parts. A true achievement of miniaturization, this new movement is even shorter than the split-second movement CHR 29-535 PS (7.1 mm).
Energy control and high precision
The Patek Philippe Grand Complication thus built is as complex as a tourbillon, minute repeater or split-seconds chronograph. The new calibre CH 29-535 PS 1/10 requires more energy for a frequency of 5 Hz and for combining the seconds chronograph with a high-speed hand. To control and limit this energy consumption, engineers had to intervene in all the nooks and crannies of motion. Of course, the word "precision" dominates the entire development of the movement.
The challenge begins with a single mainspring that powers the entire movement. Patek Philippe has redesigned this component and increased its efficiency to maintain the spring's amplitude as much as possible and ensure optimized rate stability. To increase the available energy and increase the power reserve, the diameter of the barrel arbor was reduced and the number of mainspring coils increased. The patented notch reduces the tension of the sliding strap during winding, eliminating the risk of damage due to increased forces.
High-tech adjustment mechanism
To address three challenges - efficiency, reliability and rate accuracy - Patek Philippe decided to use the Oscillomax® ensemble developed by the "Patek Philippe Advanced Research" department. Launched in 2011, this high-tech regulating mechanism has 17 patents and three innovative components that rely on all the advantages of Silinvar® technology - it is based on a silicon derivative with extraordinary physical and mechanical properties (weight Light, strong and durable), anti-magnetic, etc.). The mechanism uses a Spiromax® balance spring with a patented terminal curve and internal bosses (patented in 2017, Ref. 5650), a Pulsomax® escapement consisting of a lever and escape wheel, and a Gyromax® hairspring, and Largely modified geometry Silinvar® balance, inlaid with gold. This is the perpetual calendar "Patek Philippe Advanced Research Ref. 5550P" (2011), Patek Philippe has added the Oscillomax® ensemble to its current collection. But this decision was decisive for the outstanding performance of the new Calibre CH 29-535 PS 1/10 movement. Although the movement consumes significantly more energy, it still achieves a high rate accuracy of -3/+2 seconds per day, as specified by the Patek Philippe Seal.Audemars Piguet CODE 11.59 Replica Watch
Smooth and perfectly synchronized hand movements
Another major challenge that arose during the development of the CH 29-535 PS 1/10 movement was the display quality, especially the tenth of a second. The two chronograph displays must be perfectly synchronized. Despite the high rotational speed, the tenth of a second hand must move fluidly without jumping or vibrating. Here, too, the manufacturer's engineers develop and implement innovative solutions.
The mechanism that displays the tenth of a second receives energy from the fourth wheel of the base movement through the drive wheel. Patek Philippe designed the drive wheel in a novel two-part arrangement: the upper wheel with flexible spokes and the lower wheel with rigid spokes. Thanks to this patented anti-backlash principle that is both compact and energy efficient, the teeth of the drive wheel exert a spring force on the clutch wheel, eliminating the risk of hand vibrations.
When the chronograph is activated, the tenth of a second drive wheel (one revolution per minute) meshes with a tenth of a second pinion, which makes one revolution in 12 seconds (five times faster). To achieve this "acceleration", Patek Philippe offers a tenth of a second pinion with micro-toothing: the pinion has a diameter of 1.469 mm, a tooth height of 30 microns and a total of 136 teeth. The backlash is suppressed by the preload of the clutch wheel on the pinion. A number of individual measures maximize the accuracy of the display.
Proven shock absorbers
Another essential measure required for a user-centric solution has to do with shock absorbers. The new calibre CH 29-535 PS 1/10 has to cope with all the demands and risks that can be faced in everyday use. To this end, Patek Philippe has developed two patented mechanisms. One of them is the shock absorber hitch, which holds the clutch rocker throughout the short measurement. The second uses the "unbalance" (center of gravity, not to be confused with the center of rotation) of the tenths of a second chronograph mechanism component. In the event of an impact, the acceleration values of the impacted components are compensated instead of accumulated. The result is that all components remain in the desired position, eliminating any impact on the correct functioning of the watch.
single button chronograph
One final notable feature: the chronograph has a pusher at 2 o'clock that continuously executes start, stop and reset commands. This single-button mechanism is reminiscent of classic chronographs and will delight technical watch lovers. In addition to the patented CH 29-535 PS 1/10 movement, the new watch embodies the seamless combination of tradition and innovation that forms the core of Patek Philippe’s philosophy.Chopard Imperiale Watches
A sapphire crystal caseback (interchangeable with the solid platinum caseback supplied with the watch) allows the CH 29-535 PS 1/10 movement with its filigree components and elaborate finishes (bridges with chamfered and polished edges) plate, Geneva stripes, etc.). The gold-plated inscriptions "Oscillomax 5 Hz" and "GyromaxSi" engraved on the bridges refer to the innovative movement components.
unwavering sporty style
A movement entirely focused on performance and short measurements needs to be well protected, so Patek Philippe has created an unrivaled sporty look. To reflect this concentration of technological prowess, manufacturers chose platinum, the most precious metal and the most difficult to machine. The rounded case and the hand-wound Ref. 5370 split-seconds chronograph were launched in 2015. As a special feature, its concave bezel forms a perfect transition with the slightly domed sapphire crystal. The sides of the case are slightly recessed and satin-finished, and the lugs are subtly curved and feature cabochons at the ends of the decorative spring bars. Like all Patek Philippe models in platinum, the Ref. 5470P-001 features a flawless brilliant-cut diamond between the lugs at 6 o'clock.
The elegant blue dial complements the shimmering reflections of the platinum case, while providing the perfect contrast for the legibility of the individual displays. The chronograph seconds are indicated by sandblasted and rhodium-plated steel hands, and the minute scale is decorated with small gold pearls. Slim hands in Silinvar® show tenths of a second. Because it is so lightweight, this high-tech material saves energy and has the rigidity needed to withstand the shocks that occur when a chronograph is suddenly stopped. Thanks to a new patented process for decorating the Silinvar® hand, in this case painted red, and a second patent on the connection of pipes to the Silinvar® hand by brazing, Patek Philippe has succeeded for the first time in this Promising material for external functions of watches. The red color of the hands also echoes the markings on the railway track scale for reading tenths of a second. As long as the chronograph is not running, the red and grey chronograph hands are superimposed to look like a hand. After a short measurement using the pusher at 2 o'clock, it fires a captivating ballet at two different rotational speeds. The instantaneous 30-minute counter at 3 o’clock and the small seconds at 9 o’clock feature clear rail graduations to improve the legibility of the corresponding information. The red and grey chronograph hands overlap to look like a hand. After a short measurement using the pusher at 2 o'clock, it fires a captivating ballet at two different rotational speeds.
