Audemars Piguet’s most iconic and popular watch model is the Royal Oak, and the Openworked Double Balance Wheel is one of its most sought-after versions. The standout feature of this watch is its Double Balance Wheel mechanism, designed to enhance precision and stability. This innovation incorporates two balance wheels and springs mounted on the same axis, working together to improve timekeeping accuracy and reliability by reducing oscillation-related issues.
One common example of an oscillation-related issue comes from the constant positional changes of a watch when worn on the wrist. As the watch shifts between orientations—such as upright, flat, or tilted—gravity, friction, or uneven weight distribution can slightly affect the oscillation of the balance wheel. Over time, these variations may cause the movement to gain or lose seconds, compromising its accuracy.
The double balance wheel system counters these problems by allowing the two balance wheels to self-regulate and neutralize such disturbances. This innovative design ensures more consistent oscillations, maintaining accurate timekeeping regardless of the watch’s position.
