Patek Philippe

The Reference 5951 was launched at the Basel fair in 2010 and immediately captured its audience with its strong black, red, and white aesthetic. The new mono-pusher split-seconds chronograph wristwatch with perpetual calendar was a thrilling addition to Patek Philippe’s traditional repertoire, proving that the watchmaker not only has the skills to keep tradition alive, but also the courage and vision to innovate.

The tortue case pays tribute to some of Patek Philippe’s earliest split-seconds chronographs with an Art Deco design that dates back to the 1920s. The dial offers a highly legible, modern configuration with bold red accents.

The movement’s design is based on caliber CHR 27-525PS, the thinnest column-wheel-controlled split-seconds chronograph movement, which can be seen in reference 5959 and the reference 5950A. The CHR 27-525 PS Q boasts the addition of a perpetual calendar module that adds a mere 2.05 mm in height, creating an overall height of just 7.3 mm and making it the thinnest split seconds chronograph with perpetual calendar ever crafted by Patek Philippe. Due to its extreme complexity, the new caliber CHR 27-525 PS Q is assembled by hand, one at a time.

Approximately 150 pieces were produced before the Reference 5951 was officially retired in 2015, making the present lot one of a very limited number produced by the firm.
