Roger Dubuis Excalibur Monobalancier

by Chamath Gamage

Hyper skilled, hyper immersive, hyper exclusive. That’s what Roger Dubuis is bringing to the table at Watches & Wonders 2022. One of two releases being unveiled is the updated version of the Excalibur Monobalancier. Roger Dubuis’s releases for Watches & Wonders 2022 are centred around their legendary collection; the Knights of the Round Table. In the world of Hyper Horology, these models aren’t there to mess around with. 

Roger Dubuis like all high-end watch brands is constantly trying to reinvent the watchmaking game. With their collection of timepieces, it is easy to see why this brand is sought after and why some of the pieces leave you breathless when looking at it. This is exactly what hyper-technical craft and hyper expressive design are. Two areas Roger Dubuis thrives on. 

Deemed as the last in the evolution of the Excalibur collection, the Excalibur Monobalancier brings the brand’s visionary engineers on board to create one incredible timepiece. The already existing Excalibur Monobalancier is taken and given a makeover which gives it a series of mechanical and aesthetic improvements. 


The Roger Dubuis Excalibur Monobalancier has been reimagined to give it a more sophisticated modern look. The timepiece comes in a 42mm case that features highly contrasted decorates such as sandblasted finishes, satin-brushed surfaces, and polished angles. The Excalibur Monobalancier is available in two variants, one with an EON GOLDTM* case and an embossed black calf leather strap while the other version is an EON GOLDTM* case that has 60 round cut diamonds along with the bezel. This version comes with an embossed purple calf-leather strap. 

Both timepieces come with clean-cut lines, a fluted bezel, and sharp notches. The iconic star that is on the Excalibur Monobalancier is now being elevated on this latest release so that it appears to levitate freely above the barrel. 

The micro-rotor is displayed on the dial side at 11 o’clock and has been created from Pink Gold750/1000 and is Tungsten finished. The rotor also comes with an engraving of the Roger Dubuis monogram to make its design more modern. 


The movement in this latest Roger Dubuis Excalibur Monobalancier has been beefed up, with its performance being pushed to its limits. The new RD 720SQ calibre movement has been designed to give out an impressive power reserve of 72 hours. The micro-rotor has also been designed so that the vibrations it goes through during normal daily wear are minimised as much as possible. 

Roger Dubuis is always looking to better improve their movements and look for solutions that can do so. This is evident in the RD 720SQ movement as the Maison doubled the balance wheel inertia so that stability can be improved while also making it more resistant to shocks. The escapement wheel also now produces better efficiency and energy transmission as it is made from diamond-coated silicon and paired with adjustable diamond-coated silicon pallet stones. 

When it was Roger Dubuis’s turn to show off their latest creations for Watches & Wonders 2022, we didn’t really think they were going to be ordinary pieces, were they? The brand was determined to release some masterpieces and they have done just that with the latest edition of the Excalibur Monobalancier. Always improving, always reaching new heights of art and technical mastery, these watches show that the brand is always challenging itself to strive for new horizons.
