Royal Oak Double Balance Wheel Openworked - Audemars Piguet
This watch features the new “Dualbalance” patented geometry.

At the beating heart of the mechanical watch is its regulating organ, the balance wheel and its essential counterpart, the balance-spring. This ingenious pairing, first introduced to horology in the 17th century, acts as the watch’s control unit, determining the precision of the watch’s pulse through the regularity of its back and forth oscillations. It is a straightforward process — the swing of the balance wheel coils the balance-spring, which, when it reaches its maximum amplitude, starts to uncoil — yet it sets off a complex of transferred energies: each full swing releases a tooth of the escape wheel, moving the ensemble of precisely calibrated components and gears one increment forward. Ensuring its reliability is among the toughest engineering challenges in watch technology because, unlike a stationary pendulum clock, the evermoving wristwatch has to defy gravity, remain impervious to motion, resist changes in temperature and withstand all manners of shock.
The Royal Oak Double Balance Wheel Openworked tackles these stabilising issues by fixing a second balance wheel and balance-spring assembly on the same axis. The new “Dualbalance” patented geometry involves a very complex manufacturing procedure, but the payoff is huge: greatly improved precision and stability.
This is not only a new world-first, it is also an imposing combination of art and architecture, which is why Audemars Piguet has fully openworked the movement to reveal this two-fold beauty from both sides of the watch.
Filing, decoration and finishing are exclusively done by hand, for both aesthetic and technical reasons.
