Audemars Piguet replication Watches

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 capable of running perfectly at 43,200 vph or 6 hertz-even without any lubrication of 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 with us: gumming or hardening in 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 two well-known escapements for the day, so-called free-sprung escapement and one including energy transfer via pallet fork and guard pin part of the precursor for the modern Swiss lever escapement as introduced by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the attributes of both systems in its new high-frequency escapement, solving the oil problem and introducing a whole new and important section the sport: rate precision.”mehr sehen schweizer uhren und Breitling Skyracer
