Roger Dubuis Excalibur

About this reference

The Roger Dubuis Excalibur EX427793 is a discontinued reference produced during the mid-to-late 2000s, a period defined by the brand’s adherence to the Poinçon de Genève standards across its entire catalog. This model features a 42mm 18k white gold case characterized by the collection's signature triple lugs and notched bezel. It is powered by the manufacture Calibre RD77, an automatic movement featuring a micro-rotor and 42 hours of power reserve. The dial utilizes a silvered finish with oversized black Roman numerals and a small seconds sub-dial at 9 o'clock. Collectors value this reference for its integration of traditional Geneva seal finishing within a bold, contemporary design language. On the secondary market, this model typically trades between $10,000 and $15,000 depending on condition and the presence of original documentation. A notable production detail is the limited run of 888 pieces, a common numbering convention for the brand during this era.
