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 competent at running perfectly at
43,200 vph or 6 hertz-even without the lubrication with the pallet
stones, which would quickly dissipate at that speed anyway. The omission
of lubricant solves an issue that’s plagued watchmakers provided
mechanical timepieces have been known: gumming or hardening from the
oil.
This fresh escapement is founded on an invention by Parisian royal
clockmaker Robert Robin (1742-1799). He created a new system in 1791
that combined the virtues of the two well-known escapements throughout
the day, so-called free-sprung escapement and one including energy
transfer via pallet fork and guard pin part of the precursor towards
modern Swiss lever escapement as invented by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the advantages of both
systems in its new high-frequency escapement, solving the oil problem
and introducing a different and important component to the overall game:
