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 efficient at running perfectly at 43,200 vph
or 6 hertz-even without lubrication on the pallet stones, which would
quickly dissipate at that speed anyway. The omission of lubricant solves
a problem which has plagued watchmakers provided that mechanical
timepieces have endured: gumming or hardening with the oil.
This fresh escapement is dependant on an invention by Parisian royal
clockmaker Robert Robin (1742-1799). He created a new system in 1791
that combined the virtues present in well-known escapements throughout,
so-called free-sprung escapement and one including energy transfer via
pallet fork and guard pin within the precursor on the modern Swiss lever
escapement as created by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the important things about
both systems in its new high-frequency escapement, solving the oil
problem and introducing a completely new and important section the
sport: rate precision.”mehr sehen replica rolex und Rolex Day Date
