In a horological landscape often defined by restraint, Roger Dubuis continues to chart its own course—fearlessly avant-garde, mechanically ambitious, and resolutely contemporary. At Watches and Wonders 2025, the marque unveiled two commanding creations that deepen its Excalibur narrative while cementing its role as the flagbearer of expressive watchmaking.

The brand's latest expressions—the Excalibur Biretrograde Calendar 40 mm and the Excalibur Grande Complication 45 mm—are not merely instruments of precision but declarations of artistic and mechanical intent. Each piece extends the Maison’s conversation around radical transparency, dynamic form, and architectural mechanics, underscoring a commitment to craftsmanship that exists in perpetual motion.

From its founding, Roger Dubuis has challenged orthodoxy. Born out of a desire to meld Genevan haute horlogerie with audacious design codes, the brand has continually redefined what contemporary fine watchmaking can be. That legacy of contrast—heritage and disruption, finesse and force—is carried forward today in these two newly revealed mechanical statements.

The Excalibur Biretrograde Calendar RDDBEX1179 exemplifies Roger Dubuis' ability to harness symmetry and sophistication. Housed in a 40 mm pink gold case with a matching bezel, the watch introduces a dual retrograde calendar display—a technical feat rarely attempted with such finesse. Twin arc-shaped hands sweep across the date and day indicators before springing back to their starting points, a ballet of mechanics executed with precision and poise.

Beneath the surface lies the RD840 calibre, developed in-house and skeletonised to reveal the full theatricality of the movement. Yet this spectacle is not merely for show. Every component adheres to the stringent criteria of the Poinçon de Genève, affirming both visual and functional integrity. The aesthetic is clean yet assertive, with sharp lines, polished bevels, and dynamic depth—hallmarks of Roger Dubuis’ architectural vocabulary.

For those drawn to complexity in motion, the Excalibur Grande Complication RDDBEX1174 presents a mechanical crescendo. At its heart is a symphony of horological marvels: a minute repeater, perpetual calendar, and tourbillon—all harmonised within a single calibre. This is not simply a showcase of capability, but a distillation of over two decades of savoir-faire.

The openworked dial serves as a canvas for the movement’s choreography. Every aperture, gear, and bridge has been laid bare, inviting the eye into an ever-evolving interplay of function and form. Encased in 45 mm of sculpted titanium, this creation is at once monumental and meticulously finished—built for those who understand that mastery lies in the details.

What Roger Dubuis has demonstrated in Geneva this year is more than technical prowess. These novelties reaffirm its dedication to pushing horological boundaries while maintaining an unwavering respect for the craft. Whether exploring retrograde design or navigating the heights of grand complications, each piece is a chapter in an ongoing story—one that invites its wearer to join in its evolution.
