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 effective at running perfectly at 43,200 vph
or 6 hertz-even which has no lubrication with the pallet stones, which
would quickly dissipate at that speed anyway. The omission of lubricant
solves a problem that’s plagued watchmakers as long as mechanical
timepieces have been common: gumming or hardening in the oil.
This fresh escapement is based on an invention by Parisian royal
clockmaker Robert Robin (1742-1799). He designed a new system in 1791
that combined the virtues present in well-known escapements for the day,
so-called free-sprung escapement and one including energy transfer via
pallet fork and guard pin contained in the precursor towards modern
Swiss lever escapement as designed by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the benefits of both
systems in its new high-frequency escapement, solving the oil problem
and introducing a brand new and important ingredient of the game: rate
