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 efficient at running perfectly at
43,200 vph or 6 hertz-even without any subsequent lubrication of the
pallet stones, which would quickly dissipate at that speed anyway. The
omission of lubricant solves problems which has plagued watchmakers so
long as 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 created new system in 1791 that combined
the virtues of the two well-known escapements of the day, so-called
free-sprung escapement and one including energy transfer via pallet fork
and guard pin in the precursor into 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 a brand new and important ingredient of the experience:
rate precision.”see more svizzera rolex and Breitling Super Ocean
