Roger Dubuis Excalibur Double Tourbillon Squelette

About this reference

The Roger Dubuis Excalibur Double Tourbillon Squelette reference EX45-01SQ-20-00 was introduced around 2009 and is no longer in current production. Collectors target this reference for its 45mm 18k white gold case and the caliber RD01SQ, a hand-wound movement featuring two differential-linked flying tourbillons. This model represents the brand’s transition toward its signature "Astral Skeleton" design language, characterized by star-shaped bridges and the Poinçon de Genève certification visible on the movement components. The production was limited to 28 pieces, making it a rare find compared to later non-limited iterations. On the secondary market, this specific reference typically commands prices in the $120,000 to $160,000 range depending on provenance and service history. A notable auction result occurred in 2016 when a similar white gold example achieved approximately $130,000, confirming the sustained value of these early, low-volume skeletonized complications.
