Roger Dubuis Excalibur Monobalancier

Roger Dubuis presents Excalibur Monobalancier, the latest evolution of the iconic Excalibur collection.

For the inaugural Monobalancier edition, Roger Dubuis used EON GOLDTM, a specific 750/1000 5N gold alloy that is more resistant to tarnishing when exposed to extreme conditions.

Both contemporary and sophisticated, this Excalibur watch comes with a series of mechanical and aesthetic improvements.

Inside the watch beats RD 720SQ calibre, a brand new self-winding movement with improved performance. It offers increased power reserve up to 72 hours thanks to a new gear-train toothing and escapement optimization through its geometry. It also has improved durability thanks to new lube, and increased precision thanks to 4 Hz frequency.

The micro-rotor is optimised to minimise its vibrations, and crafted from Pink Gold 750/1000 and Tungsten finished with an engraving of the Roger Dubuis’ monogram to modernise its design.

The Maison has doubled the balance wheel inertia to improve stability and make it less sensitive to shocks. In the same way, better efficiency and energy transmission is achieved by optimising the shape of the escapement wheel, now constructed from diamond-coated silicon, and paired with adjustable, diamond-coated silicon pallet-stones, and a new lube.

The Excalibur Monobalancier watch comes with clean cut lines, fluted bezel and sharp notches, while the signature star is reshaped to levitate freely above the barrel.

A contemporary approach is further evident in the decorations amplifying the expressive nature of this 42mm timepiece, including highly contrasted decorations such as sandblasted, satin-brushed surfaces, and polished angles.

Meeting the exceptional high standards of the Poinçon de Genève, two editions are available, one with an EON GOLDTM case and an embossed black calf-leather strap, the other one also with an EON GOLDTM case and adorned with 60 round-cut diamonds and an embossed purple calf-leather strap.

Both straps feature a patented Quick Release System.
