The chronograph
We are often called upon to be able to measure the
time separating two events. This makes the chronograph
an indispensable instrument. Its invention was the
work of a watchmaker in the Vallée de Joux, Henri-
Féréol Piguet, who designed and created this system
in 1845.
Since its founding in 1875, Audemars Piguet has
been developing and making some of the most
sophisticated and ef f icient chronographs in the
world. While the tourbillon and chronograph both
faithfully reflect this philosophy, dating back over
one hundred years, the movement makes its own
mark with an exclusive chronograph mechanism,
showcasing one of the Brassus Manufacture’s latest
advances in reliability and precision.
The chronograph mechanism features a new, highly
effective coupling lever. This provides dual gearing
adjustment to ensure greater accuracy, an exclusive
Audemars Piguet innovation that also prevents the
chronograph hand from jumping when the start function
is activated.
Moreover, the 30-minute counter is equipped with
a practical device enabling a semi-instant jump of
the chronograph minute hand within an interval of
approximately half a second. The advantage of this
system lies in the facilitated time measurement
reading, since the transition from one minute to the
next occurs rapidly and gives a clear indication of
the number of minutes elapsed.
