The character of the watch king Patek Philippe 5470P comprehensive analysis

5Hz high vibration frequency, 1/10 second timing function is not the first time in the watch world. Patek Philippe launched its first high vibration frequency chronograph Ref. 5470P. It is presented delicately in a more stable, precise and high-quality form. This is the thoughtful experience that only high-end watchmaking can provide, and it is also the character of the watch king.

In order to explain the technical details of Ref. 5470P in detail, we will divide it into 2 articles. The first is an explanation of the design of Ref. 5470P and the unique double-layer timing module mechanism, and then a comprehensive analysis of Part_2 in the Patek Philippe 5470P, the character of the watch king, will focus on how Patek Philippe starts from the basic function of the movement to create a stable and accurate 1/10 chronograph for more detailed analysis.

5470P is Patek Philippe's first 5Hz high vibration frequency chronograph that can display 1/10 second timing function. Although these functions are not unfamiliar to us, after all, Zenith launched a watch with the same function as early as 2010. However, this time Patek Philippe used 31 patents (including 7 new patents) to re-discuss this function in a more intuitive and precise way, which is quite worth exploring.

Appearance Design Reading Method

Although the chronograph function is already a very familiar field for Patek Philippe, since the first fully self-made chronograph movement came out in 2006, it has continued to introduce various complex functions, or have innovative technologies and patented improved designs, more than 20 models. Chronograph works, but the 5470P's 5Hz high vibration frequency and 1/10 second timing function still surprised us.

The dial configuration of the 5470P is very close to the binocular timing function of the 5170P. The biggest functional feature is the coaxial configuration of the chronograph second hand and the 1/10 second chronograph second hand (red second hand), allowing users to intuitively read the time accurate to 1/10 of a second.

At first glance, the 5470P looks like the 5170P dual-eye timing. In addition to the 5Hz high-frequency timing function, the most functional feature is the coaxial configuration of the silver 60-second chronograph second hand and the red 1/10-second chronograph second hand. . The user can read the time accurate to 1/10 of a second more intuitively through the two chronograph seconds hands of different colors. The most amazing thing is that the 1/10-second chronograph second hand rotates at a high speed every 12 seconds, and the speed is 5 times that of the general 60-second chronograph second hand, so that the wearer can fully experience the high-frequency chronograph function. The speed of the wind is shocking.replica Jacob Co. Astronomia Sky

Challenges to Overcome with the 1/10-Second Chronograph

Philip Barat, RD director of Patek Philippe, said that in order to respond to the needs of customers and the brand's confidence in its own technical capabilities, the 5470P has been set up for the 5470P to have a high-speed visual impact, as well as a stable, smooth and precise operation. This also means that the 5470P not only needs to add a set of 1/10 second timing modules, but also needs to re-plan the power configuration after the CH 29-535 PS-based timing movement increases the vibration frequency and adjust it to a high speed. A stable system structure can also be maintained. In the end, a total of 31 patent designs including 7 new patents were used to achieve the preset goal. And all of this is to provide the wearer with the most perfect experience.

The 5470P adopts the shell shape of the 5370 family and is a single-button timing. The blue lacquered dial and blue textured strap constitute the main color of the 5470P design. The 1/10 second hand, the 1/10 SECOND words, and the strap stitching are presented in red, showing a strong sense of speed. The bottom of the case is set with diamonds between the lugs and the imprint is made of platinum.fake luxury watches

The Secret to Smooth Operation 1/10 Second Timing Module

In order to perfectly display the 1/10-second timing function, in addition to creating an unprecedented double-layer timing module, a more special structural design is required to create a perfect user experience that runs smoothly.

The CH 29-535 PS 1/10 movement carried by the 5470P uses the CH 29-535 PS double split chronograph movement that has been in service for more than 10 years as the basic movement. Since its introduction in 2009, this movement has mostly been equipped with complex functions such as annual calendar or perpetual calendar, and has excellent stability and scalability. In order to display the 1/10-second chronograph function of the movement, which originally had a vibration frequency of 4Hz (28,800 vph), in addition to increasing the vibration frequency of the movement to 5Hz (36,000 vph), the first step was to add a set of 1/10 seconds. 10-second timer module.

The Challenge of the Double Timing Module

The basic concept of Patek Philippe's CH 29-535 PS 1/10-second chronograph movement is to retain the timing module of the CH 29-535 PS double-chasing chronograph movement, cancel the upper double-chasing needle module, and then use a newly developed The 1/10-second timing module is replaced, so this movement has both a timing module and a 1/10-second timing module, two independent timing modules that are linked together.men replica watches

The newly added 1/10-second chronograph module is specially designed to drive the 1/10-second chronograph hand. The module includes a drive gear, a clutch lever and a clutch gear, and a 1/10-second pinion that carries the 1/10-second chronograph hand. In addition, there are 2 sets of shocks to stabilize the clutch lever, which we will describe in detail later. The module connects the four-wheel drive of the movement through the drive wheel, and drives the clutch wheel to run at the same time. When the chronograph function is activated, the clutch lever will drive the clutch wheel to connect with the 1/10-second pinion, so that the 1/10-second chronograph hand runs. Of particular note is the very special structure of the drive wheel, which hides the secret to making the 1/10-second chronograph hand run smoothly.

The secret to smooth needle movement

The reason for the vibration of the 1/10-second hand comes from the "backlash" between the gears, which is the gap between the gears that mesh with each other. Backlash is necessary to avoid gear seizure and to allow for lubrication, but it occurs when gears run in steps. In this 1/10 second mechanism, the drive wheel that steps 10 grids per second drives the jamming phenomenon between the clutch wheels. When the timing function is activated and the 1/10 second pinion is connected, it will run at 5 times the speed of 1. The /10 second hand is magnified into a visible vibration. And this is unacceptable for Patek Philippe.

To eliminate chatter, Patek Philippe's solution was to create a patented gear structure that eliminates backlash. It is a double-layer gear made of LIGA nickel-phosphorus alloy: the upper half has elastic gear spokes, and the lower half is rigid gear spokes, which are stacked up and down to form a gear that can eliminate backlash. Since the tooth height of the 1/10 second pinion is only 30 microns, if the clutch wheel connected to it adopts a structure that eliminates backlash, it cannot mesh with such a slender pinion, so this patented gear structure is used in the drive wheel. , so that the drive wheel and the clutch wheel can be engaged more closely, eliminating the jamming during operation. In this way, it can achieve what Patek Philippe expects to bring to the user, a smooth and precise 1/10 second hand.richard mille rm11-03 le mans
