Way back in 2006 the manufacture introduced a new escapement that
functioned at a less frenetic 21,600 vph, but even at that time tests
had shown that the AP escapement was efficient at running perfectly at
43,200 vph or 6 hertz-even with virtually no lubrication on the pallet
stones, which would quickly dissipate at that speed anyway. The omission
of lubricant solves a dilemma which includes plagued watchmakers
provided mechanical timepieces have been around: gumming or hardening
from the oil.
This fresh escapement is founded on an invention by Parisian royal
clockmaker Robert Robin (1742-1799). He launched a new system in 1791
that combined the virtues present in well-known escapements throughout
the day, so-called free-sprung escapement and one including energy
transfer via pallet fork and guard pin as part of the precursor to the
modern Swiss lever escapement as introduced by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the features of both
systems in its new high-frequency escapement, solving the oil problem
and introducing a new and important ingredient of the overall game: rate
