Roger Dubuis Excalibur Double Tourbillon Black Ceramic Limited Edition

In 2021, Roger Dubuis introduced the new evolution of the Excalibur Double Tourbillon watch. Now, the Geneva based high horology Maison unveils its latest variation in radiant black ceramic.


This new ceramic watch is driven by the Roger Dubuis RD108 mechanical calibre. Boasting two signature tourbillons, this enhanced horological engine represents a feat of enhanced precision and technical prowess. Both tourbillons are rebuilt with lighter materials and an enhanced differential to maximise the transmission of energy.

Its tourbillon lower carriage is made in titanium for improving energy efficiency and upper tourbillon carriage in cobalt chrome for better finishing: mirror polish. Both titanium and cobalt chrome are anti-magnetic. Manually wind, the RD108 calibre offers an impressive power reserve of 72 hours.


This extremely complex mechanical skeleton movement’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.

Limited to just 28 pieces, this timepiece comes with a black calf-leather strap with versatile Quick Release System.
