Roger Dubuis Excalibur Triple Time Zone

About this reference

The Roger Dubuis Excalibur Triple Time Zone (Reference DBEX0055) was produced during the mid-to-late 2000s and is no longer in current production. Collectors target this reference for its 45mm 18k pink gold case featuring the brand’s signature notched bezel and triple-lug design. It houses the in-house Caliber RD1448, an automatic movement bearing the Poinçon de Genève. The dial displays three independent time zones via two sub-dials and a central hand, alongside a power reserve indicator. This model represents the "Golden Era" of the manufacture under the founder's influence before the Richemont acquisition. On the secondary market, this reference typically trades between $15,000 and $22,000 depending on condition and completeness. A notable production detail is its limited nature; many iterations of the Excalibur Triple Time Zone were restricted to 28 or 88 pieces globally, contributing to its relative scarcity.
