Last 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 able to running perfectly at 43,200 vph or 6
hertz-even without lubrication of the pallet stones, which would
quickly dissipate at that speed anyway. The omission of lubricant solves
an issue which includes plagued watchmakers as long as mechanical
timepieces have existed: gumming or hardening within the oil.

This fresh escapement is dependant 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 of the day,
so-called free-sprung escapement and one including energy transfer via
pallet fork and guard pin included in the precursor into the modern
Swiss lever escapement as created 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 the latest and important aspect of the experience: rate
precision.”see more Hublot and Cartier
