Roger Dubuis Introduces the Excalibur Double Tourbillon and Excalibur Monobalancier in Black Ceramic

8 June 2022

By Peter Vossner

Hyper expressive. Hyper mechanical. Hyper technical.

Roger Dubuis is for the first time introducing two timepieces in black ceramic, the Excalibur Double Tourbillon and Excalibur Monobalancier, giving the two models a whole new visage.

Solidly black inside and out, Roger Dubuis' ceramic is four times harder than steel, and stands out with the Maison's refusal to compromise on the its signature shape.

The process begins with a blend of powders made of Zirconia combined with 3% stabilising Yttrium that results in its hyper-resistant hardness. Then the combined blank goes through a machining process six times lengthier than the standard. The subsequent sintering and heating takes up another 48 hours, followed by the final stage of hand-finishing the immensely hard material, which demands extreme craftsmanship and meticulous care to conquer. The end result is a case hyper-resistant to daily scratches, and an immutably bold black finish.

Refusing to tarnish or reduce in intensity over time, Roger Dubuis’ radiant black ceramic is where hyper durability meets hyper expressivity in a single timepiece. 

Excalibur Double Tourbillon in Black Ceramic

The Excalibur Double Tourbillon in its current iteration was launched last year, and it is now available also in radiant black ceramic.

Housed within this new ceramic case, the RD108 calibre and its two signature tourbillons are a feat of superlative precision and technical prowess. Both tourbillons are rebuilt with lighter materials and an enhanced differential to maximise the transmission of energy. This ultimately optimises the power reserve to 72 hours – perfect for leaving it off over the weekend.

Meanwhile, the calibre’s sense of transparency and 3D depth is heighted by the Roger Dubuis star levitating freely above the barrel. Clean cut lines on both the 45mm case and movement create its strong visual identity and give the impression of a thinner look and feel. This dynamic aesthetic is amplified by its decorations, hand-finished with precision and rewarded with the Poinçon de Geneve; one of the most demanding signatures in fine watchmaking.

Hyper durable and expressive, the latest variation of the Excalibur Double Tourbillon debuts with a radiant black ceramic case, striking in its intensely high scratch-resistance. With just 28 available, a black calf-leather strap with versatile Quick Release System completes the spectacular aesthetic of this new all-black timepiece.

Excalibur Monobalancier in Black Ceramic

The Excalibur Monobalancier, launched in an enhanced version this year, is now also available in radiant black ceramic.

Roger Dubuis for this timepiece has pushed the performance of the automatic RD 720SQ calibre to its maximum, increasing its power reserve to an impressive 72 hours. Reinterpreted with contemporary flair, the 42mm timepiece is designed with clean cut lines, fluted bezel, and sharp notches, while the signature star is reshaped to levitate freely above the barrel.

Aesthetic features include highly contrasted decorations, such as sand blasted, satin brushed surfaces, and polished angles, all of which are certified by the prestigious Poinçon de Genève. An embossed black calf-leather strap featuring a patented Quick Release System ensures ultimate versatility while offering a perfect colour match for the new unmistakably black case.

With a timepiece displaying hyper durability, expressiveness, and extreme craftsmanship, the new Excalibur Monobalancier black ceramic edition demonstrates the Maison’s ultimate mastery of the most contemporary and advanced technical materials. This is the timepiece of today.


Having encased two of its iconic calibres in ceramic and shaping it into the distinctive form that defines the Maison’s timepieces, Roger Dubuis’ unrivalled mastery and fearlessness in taking on the most difficult challenges is once again solidified. The latest black ceramic masterpieces show the Maison not only shapes the future of horological design, it is the future of horological design. Because Roger Dubuis is and always will be the most exciting way to experience Hyper Horology™.
