Intriguing. Accomplished. Disruptive. Bearing all of the hallmarks of a work of art, Roger Dubuis is proud to unveil the Excalibur Monobalancier. Crafted from EON GOLDTM, a specific 750/1000 5N gold alloy that is more resistant to tarnishing when exposed to extreme conditions. It is a timepiece that proves the only limit for Hyper Horology is one’s own imagination.

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.

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.

n 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.

SPECIFIC HIGHLIGHTS
• The new development of the Excalibur Original collection. A calibre with improved performances: increased power reserve up to 72 hours thanks to a new geartrain toothing and escapement optimization through its geometry. Improved durability thanks to new lube, and increased precision thanks to 4hz
frequency. The case of the watch is made of a new and patented type of pink gold alloy which is tarnishing a lot slower than standard pink gold. Besides, the new alloy is more resistant to challenging conditions such as salt water. This new material is called EON GOLD*.
