Roger Dubuis was founded in Geneva in 1995 by watchmaker Roger Dubuis and Carlos Dias. The brand is known for openworked movements with star-shaped bridges, bold multi-material cases and, for many years, use of the Geneva Seal across its movements. It is part of the Richemont group.
The Excalibur is the core collection, from micro-rotor chronographs to single and double flying tourbillons and the skeletonised Spider models developed with Lamborghini Squadra Corse. Earlier pieces include the Easy Diver line and tourbillon divers in titanium and carbon.
