New Audemars Piguet escapement
Taking its inspiration from Robin, the famous French
watchmaker (1742-1799), Audemars P iguet has
developed a new direct impulse escapement. This new
AP escapement combines the advantages of a
chronometer escapement (ex tremely accurate)
with those of a Swiss-lever escapement (extremely
resistant). Its innovative design and outstanding
performance render this patented system a minor
revolution in watchmaking mechanics. It heralds the
new generation of Audemars Piguet movements and
furthers the performances of the watches produced by
the Manufacture.
The new AP design hosts a number of technical
features far superior to the traditional (Swiss lever)
escapement :
Detached pin-pallet escapement : a single
impulse corresponds to two vibrations, causing
fewer set t ing disturbances and ver y high
efficiency.
Improved chronometry : the spr ing balance
isochronism may be adjusted by mov ing the
quiescent point with respect to the impulse
given to the balance ; reducing mechanical dis-
turbances at the escapement increases movement
accuracy.
Optimum long-term stability : tests conducted
over five years have shown that this escapement
displays excellent operational stability.
