Calendar complications, long the bastion of traditional watchmaking, have historically been presented through established, refined displays. However, Roger Dubuis, since its inception in 1995, has consistently challenged these conventions, most notably through its signature biretrograde system, which has become an indelible part of the brand’s aesthetic and mechanical identity. This innovative approach to displaying temporal information is brilliantly exemplified in the brand’s recent releases, showcasing a legacy of horological reinterpretation and forward-thinking design.
A Legacy of Retrograde Innovation
The genesis of Roger Dubuis’ distinctive approach to calendar complications can be traced back to the late 1980s, when founder Roger Dubuis, in collaboration with Jean-Marc Wiederrecht, co-patented a revolutionary retrograde system. This groundbreaking mechanism allowed hands to swiftly return to their starting point after completing their indicated arc, offering a dynamic and visually striking alternative to conventional, continuously moving pointers. This innovative system was not merely an academic exercise; it was integrated into the brand’s earliest timepieces, establishing a core pillar of Roger Dubuis’ horological philosophy. The brand’s commitment to this unique complication has endured, becoming a defining characteristic that differentiates its creations in the competitive haute horlogerie landscape.
The Excalibur Biretrograde Calendar: A 30th Anniversary Salute
In 2025, Roger Dubuis celebrated its 30th anniversary with the introduction of the Excalibur Biretrograde Calendar. This timepiece serves as a poignant homage to one of the brand’s foundational complications, revisiting the biretrograde display that characterized its inaugural collections. The watch masterfully employs this system to indicate both the day and the date across two distinct semi-circular scales. Upon reaching the end of their respective cycles, the hands instantly snap back to their origin, creating a captivating visual spectacle that is both highly legible and distinctively modern.
The Excalibur Biretrograde Calendar is housed in a 40mm 18k pink gold case, a choice that signifies a return to the more understated proportions favored in the brand’s earlier pieces from the 1990s. This deliberate sizing reflects a nostalgic nod to the brand’s heritage while maintaining a contemporary appeal. At its heart beats the in-house automatic Caliber RD840, a meticulously crafted movement operating at a frequency of 28,800 vibrations per hour and boasting a substantial 60-hour power reserve. Crucially, this caliber proudly bears the prestigious Poinçon de Genève hallmark, a testament to its exceptional quality, craftsmanship, and origin, attesting to the rigorous standards upheld by the Manufacture.
The dial of the Excalibur Biretrograde Calendar is a symphony of refined materials and thoughtful design. The day and date are presented through the aforementioned biretrograde system, often referred to as "ecliptic counters," which arc gracefully across the dial. A small seconds sub-dial at the 6 o’clock position provides a balanced visual counterpoint to the "Biretrograde Calendar" inscription at 12 o’clock. The choice of pink gold for the case and mother-of-pearl for the seven-layered dial is a deliberate reference to materials Roger Dubuis explored extensively in its early collections. Indeed, Roger Dubuis holds the distinction of being the first watchmaker to integrate 18k pink gold and mother-of-pearl in men’s watches, a pioneering combination that continues to define the brand’s opulent aesthetic. This exquisite pairing is complemented by a rich brown calfskin strap, featuring an interchangeable quick-release system for enhanced versatility, and secured by a matching pink gold folding clasp.
Design Continuity and Heritage Elements
Beyond the intricate mechanics, the Excalibur Biretrograde Calendar seamlessly integrates design elements that have become synonymous with contemporary Roger Dubuis. These include the distinctive triple-lug case, a hallmark of the Excalibur collection, which lends a bold and architectural presence to the timepiece. The sharply fluted bezel, another signature feature, adds a layer of tactile and visual sophistication. Furthermore, the signed double-sided flange contributes to the watch’s overall depth and complexity, showcasing the brand’s meticulous attention to detail. These enduring design cues ensure that the Excalibur Biretrograde Calendar is instantly recognizable as a Roger Dubuis creation, even as it pays homage to its historical roots.
The Hommage La Placide: A Fusion of Perpetual and Biretrograde Calendars
Further expanding on the brand’s anniversary offerings, the Hommage La Placide presents a more complex and exclusive interpretation of Roger Dubuis’ expertise in calendar complications. Limited to a mere 28 pieces worldwide, this exceptional timepiece artfully merges a perpetual calendar with a biretrograde display, uniting two complications deeply intertwined with the brand’s formative years.
At the core of the Hommage La Placide lies the Poinçon de Genève-certified Caliber RD1472. This sophisticated movement is a marvel of horological engineering, representing a harmonious blend of restored RD14 base movements, originally introduced in the early 2000s, and the RD72 perpetual calendar module, first developed in 1999. This hybrid construction is a profound statement of Roger Dubuis’ dual commitment to the art of watchmaking restoration and the development of intricate complications. The perpetual calendar mechanism is designed to accurately track the Gregorian calendar, including leap years, without requiring manual correction until the year 2100, a testament to its advanced design and engineering.
The display of the full calendar information—day, date, month, leap year, and moonphase—adheres to the brand’s signature biretrograde aesthetic. The day and date are presented across sweeping semi-circular scales, which are wider at their outer edges and taper towards the center, creating a dynamic visual flow. The watch is presented in a refined 38mm 18k pink gold case, a size that echoes the more classical proportions of earlier Roger Dubuis timepieces, offering a discreet yet luxurious presence on the wrist.
The dial of the Hommage La Placide is a layered masterpiece, showcasing Roger Dubuis’ penchant for intricate finishing and material interplay. It combines mother-of-pearl segments for the calendar indications with a lacquered "Leman Blue" base, a subtle yet evocative reference to the picturesque Lake Geneva. A captivating blue aventurine moonphase display adds a celestial dimension to the dial, while applied gold hour markers and indices provide a touch of opulence and enhance legibility. The watch is completed with a sophisticated blue leather strap, equipped with the brand’s interchangeable system for ease of wear, and secured by a matching pink gold buckle, reflecting Roger Dubuis’ contemporary focus on wearability and user experience.
