Mono-pusher chronograph flyback Patek Philippe 5950A

Steel is now just as popular in haute horlogerie as platinum and different colors of gold (see the vortex Jaeger-LeCoultre on stainless steel case ) . We can see the success of ladies diamond watches , than the legendary Nautilus and records achieved during auctions by historical models Patek Philippe steel 1940s.

To understand respect for artisans to manufacture this material watchmaker , simply place a Patek Philippe chronograph movement under the microscope and see how carefully any steel surface of the measuring short time was completed .

Why a template containing steel components worked so noble could he not beat in a housing of the same metal ? No sooner said than done. With reference 5950A (A for steel) , Patek Philippe once again opens new avenues , such as manufacturing has already done with the Nautilus and Twenty4 .

CHR 27-525 PS caliber , the chronograph mono-pusher split- motion world's thinnest
The first thing that strikes you about the new chronograph mono- pusher split Patek Philippe is the profile of its case , thinner than many simple three-hand watches . This achievement is the result of the CHR 27-525 PS caliber beautiful , which helped establish the manufacture of the new record in 2005 chronograph movement split wheeled the world's thinnest columns. As usual with Patek Philippe , the size designation provides essential information : chronograph , 27 mm diameter , 5.25 mm in height, Small Seconds .

To develop the first chronograph movement entirely designed in workshops , manufacturing in 2003 created a special cell . This unit should not only strive to set a new record , but also work on innovative solutions for future movements Patek Philippe chronographs . Among these innovations face a 60-minute trailing in tune with the road ( gear timer ) .

When the chronograph is running , the minute counter wheel is driven by the reference for setting the time , concentrically mounted freely on the axis of minute counter . The power transmission is ensured by two springs of friction between the wheel minute counter and the axis of reference. the
friction on the axis of the wheel chronograph - which prevents the quaver of the chronograph - is then offset by the elimination of friction between the reference for setting the hour and minute counter wheel .

When the chronograph is stopped , the brake or the hammer reset blocks the minute counter wheel and the axis of the reference time setting idles between two friction springs . This construction makes it possible to make one stone by reducing the height of the movement, while providing a system of compensation differences between couples chronograph switched on and off.
