Roger Dubuis and Carlos Dias co-founded the brand in Geneva in 1995. Roger Dubuis was a veteran complications watchmaker who had spent 14 years at Patek Philippe restoring vintage complicated movements; Dias was a marketing entrepreneur. The pair launched the brand around a specific commitment: every movement the house produced would carry the Poinçon de Genève (Geneva Seal), the oldest watchmaking quality certification in continuous operation, dating to 1886 and administered by the canton of Geneva.
Early references like the Sympathie (1995) and the Hommage established a reputation for extreme hand-finishing, with anglage and Côtes de Genève decoration executed to observatory standard on limited-edition double-tourbillons and perpetual calendars. In 2001 the brand moved to a new purpose-built manufacture in Meyrin on the outskirts of Geneva, and in 2008 Richemont acquired a controlling stake, integrating the brand into the group alongside Vacheron Constantin, Piaget, and IWC.
Under Richemont the brand's identity shifted decisively toward the modern Excalibur, launched in 2005, and especially the Excalibur Spider (2013), a deliberately aggressive skeletonised sports watch with exposed bridges, rubber-titanium case materials, and bright colour accents. The skeleton tourbillon became a signature complication. Partnerships with Lamborghini Squadra Corse (Excalibur Aventador S, Huracán) and Pirelli (recycled racing-tyre straps and case-back detailing) define the brand's 2015-onward era. Entry-level Excalibur pieces start around CHF 13,000, skeleton tourbillons exceed CHF 200,000, and the rare grand-complication references reach CHF 500,000+.
