A Collection Of Three Complex Functions Patek Philippe 5208r

PATEK PHILIPPE Grand Complications 5208R Technical Features:
● Three questions function
● Perpetual calendar function
● Single push button timing function
● Silinvar® silicon parts
PATEK PHILIPPE’s Ref. 5208R launched in 2018 in rose gold. It is based on a three-question device movement, and the perpetual calendar module that must drive the display is placed on the top layer of the side of the face plate. The middle part of the three-layer movement, that is, the middle of the perpetual calendar and the three-question plate, because the ten-lobed gear that connects the timing device and the perpetual calendar is blocked by the plate, it cannot pass directly through the seconds gear to connect with the perpetual calendar component. Therefore, a detour arrangement is made, which requires horizontal movement and rotation before returning to the central drive of the perpetual calendar to drive the hour, minute and perpetual calendar. The small seconds at only 6 o’clock are directly powered by a mandrel. Because of the addition of the timing module, the old movement has also been completely redesigned, greatly increasing its complexity.
High complexity does not affect the convenience of visual reading
The 5208R instant conversion perpetual calendar module is the same as the 5207 of 2008. The three-window display is one of the most convenient perpetual calendar displays. Frankly speaking, no matter how large the table diameter is, once the information on the faceplate is crowded, It is naturally inconvenient to read, and the window with black characters on black background is obviously much clearer than the small pointer; moreover, the main calendar information is arranged on the top half of the dial, which is quite clear at a glance. Generally, the perpetual calendar device usually needs 20 minutes or several hours for daily conversion. Depending on the day, you may also need to change the date, day of the week, month, and leap year at the same time. The date dial will switch from 1 to 4 days. In particular, the weight of the display panel is several times heavier than that of the pointer, and the kinetic energy required at the moment of switching is greater and more accurate, so as to avoid over-conversion or incomplete conversion. The 5208R R CH 27 PS QI self-winding movement uses a large yoke bar with 15 components to drive the display of the perpetual calendar device, ensuring that all windows can be completed simultaneously in an instant.
Pioneer of PP using silicon parts
In addition to its rare functional complexity, the 5208 is also the pioneer of top-of-the-line complication watch series using Silinvar® silicon parts, including the Pulsomax® escapement system and Spiromax® hairspring. Physical characteristics, such as lubrication, have been improved, both in terms of accuracy and operating efficiency, and they have also significantly reduced the frequency of maintenance. Patek Philippe’s Silinvar® converts the molecules on the silicon surface into Silinvar®, and uses deep reactive ion etching (DRIE) processing technology to more accurately shape the part. The entire silicon escapement is not just a change in material. The detailed adjustment of various parts at the same time makes the mechanical performance better, including reducing the escapement gear teeth from 20 to 16 teeth, and the tail end of the hairspring has also been thickened. , Let it be retracted and balanced like the Breguet gossamer, and improve the shape of the fork teeth of the pallet fork. Many improvements have made the whole picture of the development of silicon raw materials.

POINT1 loaded timing module

Because it is equipped with a timing function, the movement has made quite a lot of changes in the arrangement of the wheel train, which can be regarded as a completely new design.

POINT2 movement three-layer structure

The 5208P is based on a three-question basic movement, with a timing module in the middle and a perpetual calendar module in the upper layer. It combines three functions in one breath.

POINT3 Significant Silicon Age

Silinvar® has many subsequent applications starting from 5208, and at the same time heralds the arrival of a new generation of PP silicon escapements.

POINT4 Simplified Pasta

It has both a perpetual calendar and a timekeeping function. In order not to make the faceplate look too cluttered, Patek Philippe chose to make good use of the window and the small second dial to distinguish different functions.
