prEcISIoN
apart from the intrinsic progress in the audemars
Piguet escapement, the calibre 2908 stands out for
its very high frequency. this is so far uncommon in
the world of haute horlogerie. it is twice as efficient
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 the oscillation frequency
of the variable inertia balance improves movement
accuracy, making the watch more resistant to impact
and other factors that can affect balance. the two
parallel barrels provide a power reserve of at least a
90 hours, amply offsetting the extra power needed
for the 43,200 vph frequency.
adVanTages of The parallel barrel sysTem
reduces pressure in the gearing
the friction in the barrels is used to offset torque
variations
increased running precision, a greater power
reserve and enhanced reliability
