The Excalibur Double Retrograde Perpetual Calendar marks a significant evolution in Roger Dubuis' grand complication lineup. Following the 2024 Hommage La Placide tribute, this new model integrates the iconic double retrograde module into the futuristic Excalibur series, offering a fresh aesthetic while retaining the technical brilliance of the original 1999 patent.

Design and Construction

Crafted from KingGold, the 40mm case strikes a refined balance between classic proportions and modern flair. Measuring just 12.25mm thick, it sits comfortably on the wrist, despite housing a complex perpetual calendar. The case's 100-meter water resistance ensures durability, making it suitable for daily wear despite its haute horlogerie nature.

The dial is a layered spectacle, featuring seven levels of openworked architecture. The retrograde date and day indicators sweep across two blue mother-of-pearl arcs, similar to bridges over a starlit river. At 12 o'clock, the month and leap-year subdial, along with the moon phase at 6 o'clock, are also crafted from the same iridescent material, creating a harmonious celestial theme.

Movement: RD850 Caliber

The heart of this timepiece is the new RD850 caliber, an enhanced version of the original double retrograde perpetual calendar movement. Roger Dubuis re-engineered half of its components, including plates, bridges, and gears, resulting in a 435-part movement with a 60-hour power reserve. The moon phase is exceptionally accurate, requiring correction only once every 122 years, and a month corrector simplifies manual adjustments.

This movement is certified with the Geneva Seal, a hallmark of superior finishing and decoration. The openworked dial and caseback reveal the intricate machinery, showcasing the brand's commitment to haute horlogerie excellence.

Exclusivity and Availability

Produced in a limited series of 188 pieces, the Excalibur Double Retrograde Perpetual Calendar remains highly exclusive, though more accessible than the 28-piece Hommage La Placide. Collectors seeking a modern interpretation of a legendary complication will find this a compelling addition to their collection.
