Back 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 which has no lubrication of the pallet stones, which
would quickly dissipate at that speed anyway. The omission of lubricant
solves a challenge that has plagued watchmakers provided that mechanical
timepieces have been around: gumming or hardening of the oil.
This fresh escapement will depend on an invention by Parisian royal
clockmaker Robert Robin (1742-1799). He created a new system in 1791
that combined the virtues of the well-known escapements during the day,
so-called free-sprung escapement and one including energy transfer via
pallet fork and guard pin part of the precursor for the modern Swiss
lever escapement as invented 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 completely new and important ingredient of the game: rate
precision.”mehr sehen fake uhren und Rolex DateJust
