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 effective at running perfectly at 43,200 vph
or 6 hertz-even without any subsequent lubrication with the pallet
stones, which would quickly dissipate at that speed anyway. The
omission of lubricant solves problems that’s plagued watchmakers so long
as mechanical timepieces have been known: gumming or hardening of your
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 the two well-known escapements throughout, so-called
free-sprung escapement and one including energy transfer via pallet fork
and guard pin included in the precursor towards the modern Swiss lever
escapement as created 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 section the game: rate
precision.”see more Panerai copia and Breitling orologi
