Audemars Piguet imitation Watches

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 effective 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 challenge containing plagued watchmakers as long as mechanical timepieces have existed: gumming or hardening of the oil.
This fresh escapement draws on an invention by Parisian royal clockmaker Robert Robin (1742-1799) high quality watches. He produced new system in 1791 that combined the virtues of these two well-known escapements during the day, so-called free-sprung escapement and one including energy transfer via pallet fork and guard pin contained in the precursor to the modern Swiss lever escapement as invented 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 different and important aspect of the overall game: rate precision.”see more montre marque and Breitling Navitimer
