The equalising round table is key to the world of King Arthur’s legend. Though this essential set-up is non-negotiable, creating a design born from this concentric requirement provided a challenge the incredible watchmakers were not afraid to take on. Displaying true technical prowess, the Monotourbillon emerges from the centre of the timepiece in a powerful demonstration of advanced mechanics.

Becoming the shield against the gravitational force endangering the heroes and precision alike, the knights stand proudly around this iconic feat of engineering knowing they will tackle their common invisible enemy together.

Just as the twelve knights take their duty to protect the realm seriously, the Maison’s quest for peak performance is realised by expanding the diameter of the balance wheel to increase stability and ensure the movement is less sensitive to gravity’s effects. An accomplishment Roger Dubuis is proud to showcase in one timepiece: the pinnacle of its artistic collection combined with one of its signature complications.
