TradiTion and innoVaTion
Audemars Piguet has always striven to safeguard and
uphold its independence. This is why the company
developed its own method of crafting mechanisms,
particularly with the design of Audemars Piguet
calibres. every aspect bears the unmistakable AP
signature – bridges arranged harmoniously side by
side, hand-finished and embellishments components –
and presents elegant equilibrium, further enhanced
by the angular balance cock.
The selfwinding chronograph
We are often called upon to be able to measure the time
separating two events. This makes the chronograph
an indispensable instrument. A watchmaker from
the vallée de joux - Adolphe nicole - invented the
modern chronograph, lodging the first patent for
this complication in 1844.
The Audemars Piguet chronograph is a wrist watch
which rewinds automatically. The movements of
the wearer’s wrist generate the energy required for
it to function.
This energy, harnessed by a 22 carat gold oscillating
weight, is transmitted to the mainspring by a
gear-train. As it gradually winds around the barrel-
arbor, the spring accumulates energy that is then
transmitted to the watch movement at a steady rate.
The maximum power reserve is reached after a period
of time varying from several hours to several days,
depending on the owner and the amount of activity.
To prevent overtensioning, the barrel spring is
released at just the right moment by a sophisticated
system.
The TachomeTer
in watchmaking, the tachometer is a graduated dial
that allows you to determine the average speed taken
to cover a given distance, generally 1,000 metres.
This speed is usually expressed in km/h and is read
directly on the dial via the chronograph hand. Your
watch allows you to read speeds from 60 to 600 km/h.
