Back 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 with no lubrication from the pallet stones, which would
quickly dissipate at that speed anyway click here.
The omission of lubricant solves a difficulty containing plagued
watchmakers provided mechanical timepieces have been with us: gumming or
hardening from the oil.
This fresh escapement will depend on 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 within the precursor into the modern Swiss
lever escapement as created 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 a different and important aspect of the action: rate
precision.”see more rolex replica and Breitling Longitude
