Introduction To Patek Philippe Ref.5204 Chronograph Watch

Patek Philippe’s classic chronographs can generally be divided into three categories: pure chronographs, pure chronographs with perpetual calendar, and two-second chronograph hands with perpetual calendar. The launch of the Ref. 5204 perpetual calendar two-second chronograph watch represents the perfect ending of the classic Patek Philippe chronograph series.

The classic Patek Philippe manual winding watch with horizontal clutch and star wheel features three complex functions, highlighting Patek Philippe’s superb watchmaking tradition. Today, its patented chronograph movement joins two of the most popular complication functions, the perpetual calendar function and the two-second follow-up hand function. The movement number of this super complex watch is chr 29-535 PS Q. The perpetual calendar (Q) uses the same configuration as the Ref. 5270 chronograph that debuted a year ago. However, the designers of Patek Philippe have significantly improved the design of the two-second chronograph (R). The new two-second chase-hand separation device reduces moving parts, reduces bearing burden, and improves amplitude stability; its patented equalization device ensures the precise overlap of the chronograph second hand and the chase second hand. This masterpiece of micromechanics is housed in a classic round platinum case, beneath the milky white gold dial. Through the sapphire crystal cover, you can enjoy the movement of the movement. The wearer can also choose to replace the sapphire crystal cover with the full platinum cover that comes with the watch if he is not disappointed with the beauty.

Until the launch of the CH 29-535 PS chronograph movement, Patek Philippe chronographs used 27-70 movements. This movement was purchased externally and was specially manufactured by Nouvelle Lémania according to Patek Philippe’s special technical specifications. The movement has been assembled and finalized in Geneva; in the eyes of many enthusiasts, it was the best and most beautiful chronograph movement in the world.
This movement was once a benchmark for the manufacture of chronographs, and it was not until the launch of Patek Philippe’s magnificent chronograph development plan in the new millennium; in 2005, this plan gave birth to the world’s thinnest two-second chronograph chronograph movement CHR 27- 525 PS reached its peak; in 2006, Patek Philippe launched an automatic winding CH 28-520 IRM QA 24H chronograph movement with an annual calendar; in 2009, the Swiss watchmaker introduced a manually wound star column with a horizontal clutch CH 29-535 PS Chronograph Movement. The completion of the series has won unanimous praise from the watch industry. This laid a solid foundation for the classic chronograph series with a variety of complex functions based on a patented movement. Counting three basic Patek Philippe chronograph movements and the chronograph module of Ref. 5208 triple complication watch, Patek Philippe launched eight chronograph movements in just six years.
八 These eight chronograph movements belong to more than 50 movement series independently developed and manufactured by Patek Philippe. There are 17 basic movements of the watch, including a variety of simple manual and automatic winding movements, with tourbillon, perpetual calendar, annual calendar, minute repeater and astronomical functions.
