Audemars Piguet imitation Watches

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
