Following an astonishing Monotourbillon release in 2021, this is the second dedicated launch between these two partners. This time, the iconic tattoo artist Dr. Woo steps back into Roger Dubuis’ most important room, the Manufacture itself, to lend his skilful touch to the Excalibur Monobalancier.

In 2022, this renowned timepiece was recrafted and reshaped with clean-cut lines along the case and movement and a palette of modern materials, turning it into the perfect playground for the Maison’s collaboration with its Urban Culture Tribe. Through exceptional skill and watchmaking ingenuity, the Excalibur Monobalancier is now the ultimate canvas for creativity.  For Dr. Woo, the inspiration heads towards complex surfaces of ceramic, where time moves between the forces of the sun, earth, and moon.

    The voyage into this powerful Monobalancier watch begins on the dial, where three celestial bodies take centre stage. Between 10 and 11 o’clock, you’ll find the fiery rotation of the sun, laser-engraved with meticulous lines, shapes, and dots on a PVD black brass plate. Covering the calibre’s micro-rotor, the plate is in constant motion, churning quickly and hypnotically as the wearer moves their wrist.

    Next is the Earth. Covering the barrel between 4 and 5 o’clock, this revolving energy source is once again embellished with Dr. Woo’s delicate art and is ingeniously linked to the turning of the watch’s hands. This allows the disc to complete one peaceful turn every 6 hours and 40 minutes (or 3.6 rotations per day).


    Finally, the design journey passes via the moon. A slender crescent at 8 o’clock, adorned in fine circles and lines, and beautifully revealing the inner workings of the balance wheel beneath. The wondrous sliver of light represents a waning crescent moon, a meaningful time associated with intuition and understanding.

    As if staring into the night sky, this fantastic vision of spiralling components has a transfixing quality that will captivate the wearer for hours. The theme is further replicated on the caseback, where the sun, Earth, and moon have been inscribed alongside Dr. Woo’s own name.

    The 42mm ceramic case is engraved with Dr. Woo’s symbolic language. From sharp triangles that bounce forth from the ground to full circles that represent infinite human connection, his enigmatic iconography surrounds the bezel and flange.

    Open to its own interpretation, the distinctive array of geometric symbols is curious and compelling and is also stamped on the calf-skin leather strap. To enable personal creativity to shine, the strap features a versatile quick release system, enabling the wearer to switch it in seconds.


    The Excalibur Dr. Woo Monobalancier is powered by the automatic RD720SQ, a calibre already well-known for its performance. The micro-rotor, covered by the sun, is designed to minimise vibrations, while the remarkable inertia of its balance wheel maximises stability and reduces its sensitivity to shocks. The advanced mechanics of the diamond-coated silicon escapement wheel, paired with diamond-coated silicon pallet-stones, ensure an impressive 72 hours of power reserve, bringing even more practicality and comfort to the wearer.
