High frequency and precision
In addition to the intrinsic advantages of the AP
escapement, the new Calibre 2908, which powers this
latest addition to the Jules Audemars collection, offers
exceptional frequency hitherto unseen in the world
of f ine watchmaking. It is twice as ef f icient as
conventional designs, boasting 43,200 vph (6 Hz), and
marks a major milestone in the AP watchmakers’ long-
standing quest for improved accuracy. The increase
in balance oscillation—with its var iable iner tia
system—significantly enhances timekeeping, making
the watch more resistant to impact and other fac-
tors that can affect balance. The two parallel barrels
provide a power reserve of at least a 72 hours, amply
offsetting the extra power needed for the 43,200 vph
frequency.
Advantages of the parallel barrel system
Reduced pressure in the gears
Friction in the barrels used to cancel out the
variations
