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