Radical, powerful, and utterly uncompromising, the Roger Dubuis Excalibur Quatuor 48mm (DBEX0439) stands at the very pinnacle of contemporary haute horlogerie. As one of the most innovative mechanical watches of our time, the Excalibur Quatuor is the embodiment of the Maison’s fearless spirit and boundless ingenuity, painstakingly crafted in Geneva and certified by the esteemed Poinçon de Genève.

The commanding 48mm case is sculpted from robust 18K rose gold, its bold notched bezel and dynamic lines epitomizing the strong DNA of the Excalibur collection. Beneath the anti-reflective sapphire crystal lies a jaw-dropping skeletonized dial, where engineering prowess is on full display: four sprung balances—arranged in pairs at the corners—beat in perfect synchrony, a world-first technical marvel that compensates instantly for the effects of gravity on accuracy. The result is an ultra-precise mechanical ballet, further highlighted by the openworked bridges and the captivating architecture of the hand-finished movement.

Rose gold dauphine hands and applied hour markers ensure uncompromising legibility amidst the mechanical spectacle, while the sapphire case back provides a privileged view of the exceptional in-house caliber and its 590 individual components, each finished to Geneva Seal standards.

Engineered for sophistication and performance, the Excalibur Quatuor comes equipped with a luxurious black alligator strap, fastened by an 18K rose gold folding clasp. Despite its technical complexities, it boasts a practical 5 bar (50 meter) water resistance—making it as robust as it is remarkable.
