Roger Dubuis Excalibur Double Tourbillon

About this reference

The Roger Dubuis Excalibur Double Tourbillon reference EX45-01-50-00/0RR01/B was produced during the mid-to-late 2000s and is no longer in current production. Collectors target this 45mm 18k white gold model for the RD01 manual-wind movement, which features two differential-linked flying tourbillons and carries the Poinçon de Genève. The dial is characterized by oversized Roman numerals and a skeletonized view of the escapements. This reference represents the brand’s transition into high-complication technical aesthetics under the original vision of Roger Dubuis. On the secondary market, this specific white gold model typically trades in the $60,000 to $90,000 range, depending on provenance and service history. A notable production detail is that this reference was often limited to 28 pieces globally, a common restriction for the brand's high-complication white gold variants during that era, ensuring relative scarcity compared to later mass-produced iterations.
