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 which has no lubrication from the pallet stones, which
would quickly dissipate at that speed anyway. The omission of lubricant
solves a dilemma which includes plagued watchmakers so long as
mechanical timepieces have been known: gumming or hardening in the oil.
This fresh escapement is dependent on an invention by Parisian royal
clockmaker Robert Robin (1742-1799). He launched a new system in 1791
that combined the virtues present in well-known escapements through the
day, so-called free-sprung escapement and one including energy transfer
via pallet fork and guard pin part of the precursor to the modern Swiss
lever escapement as designed by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the benefits of both
systems in its new high-frequency escapement, solving the oil problem
and introducing a whole new and important component to the overall game:
rate precision.”see more replica Breitling orologi and replica Burberry
