"Revolution in time: Patek Philippe's Ref. 5960P Annual Calendar Chronograph"

Patek Philippe, Geneva January 26, 2006

"Aficionados have long awaited a new Patek Philippe chronograph. Now, a year after having presented the world's thinnest split-seconds chronograph, the Geneva workshops can delight connoisseurs with a new, self-winding chronograph wristwatch which is crafted entirely in-house: the Patek Philippe Ref. 5960P Annual Calendar Chronograph.

The new Ref. 5960P is a complicated wristwatch with functions that are truly useful in everyday life. It features a totally new self-winding chronograph movement developed and manufactured by Patek Philippe and endowed with a further complication: the patented Annual Calendar mechanism.

The new caliber: Tradition and innovation in perfect harmony

The new CH 28-520 IRM QA 24H chronograph caliber is a self-winding mechanical movement with a flyback column-wheel chronograph, power-reserve indicator, Annual Calendar, and day/night display. It beats at a frequency of 28,800 semi-oscillations per hour (4 hertz), assuring an extremely constant balance amplitude and high rate accuracy. The winding power is delivered by a unidirectional 21K gold central rotor. Like all Patek Philippe mechanical movements, this new caliber displays the prestigious Geneva Seal.

The chronograph mechanism is based on the venerable column-wheel principle for controlling the start/stop commands. However, it differs from classic Patek Philippe column-wheel chronographs by virtue of a remarkable innovation: The clamps do not control the engagement of a lever-mounted clutch wheel with the chronograph train but instead act on a disk clutch that transmits (chronograph running) or interrupts (chronograph stopped) the power between the fourth wheel and the chronograph hand. This is a highly reliable solution that eliminates the occurrence of backlash-induced hand jitter or bouncing because it does not involve the sudden meshing of teeth when the chronograph is started. It also replaces the conventional three-wheel chronograph train that for reasons of wear made it inadvisable to keep the chronograph running permanently. In this movement, the chronograph hand can be used without hesitation as a continuously running seconds hand; because this has no negative impact on the rate accuracy of the watch, the subsidiary seconds dial customarily found in many chronographs is no longer needed............."
