Way 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 with virtually no lubrication on the pallet
stones, which would quickly dissipate at that speed anyway. The omission
of lubricant solves a difficulty that has plagued watchmakers so long
as mechanical timepieces have endured: gumming or hardening with the
oil.
This fresh escapement uses an invention by Parisian royal clockmaker
Robert Robin (1742-1799). He created new system in 1791 that combined
the virtues of these two well-known escapements during the day,
so-called free-sprung escapement and one including energy transfer via
pallet fork and guard pin included in the precursor on the modern Swiss
lever escapement as designed by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the great things about both
systems in its new high-frequency escapement, solving the oil problem
and introducing the latest and important component to the sport: rate
precision.”mehr sehen fake rolex und Schweiz Rolex
