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 effective at running perfectly at
43,200 vph or 6 hertz-even without having lubrication in the pallet
stones, which would quickly dissipate at that speed anyway. The omission
of lubricant solves problems which includes plagued watchmakers
provided mechanical timepieces have endured: gumming or hardening on the
oil.
This fresh escapement uses an invention by Parisian royal clockmaker
Robert Robin (1742-1799). He produced a new system in 1791 that combined
the virtues of the well-known escapements throughout, 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 advantages of both
systems in its new high-frequency escapement, solving the oil problem
and introducing the latest and important component to the overall game:
rate precision.”see more bracelet montre and Bell & Ross replica
