Jules Audemars Chronometer with Audemars Piguet Escapement

The new escapement have been developed are based on the direct impulse principle. Direct impulse means the escape wheel supply impulse directly to the balance. It's obvious that the escape wheel, due to its unidirectional movement, can only deliver impulse in one direction. As the balance swings back and forth, this direct impulse principle inevitably supplies single impulses - one impulse for any two vibrations or said differently one per oscillation.

Such 'lost stroke' escapements have a distinctively different sound as well; other than the well known tick - tock of a conventional lever escapement, it's more like a tick - - tick, with the lost stroke almost not audible
Runs at 43,200 beats per hour (6 Hz)
Audemars Piguet's escapement—the small assembly that releases energy in accordance with the beat of the oscillating balance wheel—employs a substantially different layout than the traditional anchor design used in practically every mechanical watch. The new configuration is more energy-efficient and requires no lubrication.

And here is another entry into the escapement wars..

Amazing!!!. Thank you!!!. Cheers!!!, Sergio.

very good animation!. However the double hairspring wheel is difficult to adjust.
