Opus 12 defies the conventional rules of watchmaking, giving birth to the most improbable mechanical concept. This exceptional timepiece deliberately overturns the perception of time by drawing its inspiration from the Copernican revolution.
In most watches the evolution of time is imperceptible. Opus 12, on the other hand, goes into action in a remarkable way, its hands changing the guard every five minutes. At each change of the hour, the movement executes a very elaborate drill exercise by the successive rotation of the hands. Below the retrograde indication, a floating small seconds hand graduated on a translucent ring passes above a power-reserve indicator.
