Calendar complications, often seen as the bedrock of traditional horology, embody a legacy of precision and refined aesthetics painstakingly developed over centuries. Yet, within this storied domain, certain watchmaking houses have consistently challenged convention, infusing established mechanisms with a signature avant-garde spirit. Since its inception in 1995, Roger Dubuis has stood as a prominent example of this ethos, most notably through its distinctive biretrograde display, a complication that has become an indelible element of the brand’s visual identity and technical prowess. This approach is perhaps best exemplified by the recent revival and reimagining of its calendar complications, showcasing a deep connection to its heritage while projecting a bold vision for the future of haute horlogerie.
A Legacy of Biretrograde Innovation
The genesis of Roger Dubuis’ unique take on calendar functions can be traced back to the brand’s foundational years. The biretrograde system, which allows indications to sweep across a semi-circular arc before instantaneously returning to their starting point, was not merely an aesthetic choice but a cornerstone of the brand’s initial technical identity. This complication was famously co-patented in the late 1980s by Roger Dubuis himself and Jean-Marc Wiederrecht, a partnership that laid the groundwork for many of the brand’s early, groundbreaking timepieces. This foundational work has resurfaced and been reinterpreted in a series of significant releases, underscoring the enduring relevance of this sophisticated mechanism.
The Excalibur Biretrograde Calendar: A 30th Anniversary Homage
In 2025, to commemorate its 30th anniversary, Roger Dubuis introduced the Excalibur Biretrograde Calendar, a watch that eloquently revisits one of the brand’s earliest and most iconic signatures. This timepiece serves as a testament to the brand’s commitment to honoring its horological roots while simultaneously pushing the boundaries of contemporary watch design. The biretrograde display, central to this model, meticulously indicates the day and date across two distinct semi-circular scales. The elegance of this system lies not only in its technical complexity but also in its immediate legibility and striking visual appeal, a hallmark of Roger Dubuis’ design philosophy.
The Excalibur Biretrograde Calendar features a 40mm case crafted from 18k pink gold, a dimension that deliberately harks back to the more understated proportions favored in the brand’s early collections from the 1990s. Powering this exquisite timepiece is the in-house automatic Caliber RD840, a movement that operates at a frequency of 28,800 vibrations per hour and boasts a substantial 60-hour power reserve. Crucially, the movement is adorned with the esteemed Poinçon de Genève (Geneva Seal), a mark of exceptional craftsmanship and origin synonymous with the highest standards of Swiss watchmaking.
On the dial side, the day and date are elegantly presented through the signature biretrograde system, also referred to by the brand as ecliptic counters. Complementing these indications is a subdial for the small seconds positioned at the 6 o’clock position, which artfully balances the “Biretrograde Calendar” inscription at 12 o’clock. The choice of pink gold for the case and the use of mother-of-pearl for the seven-layered dial are deliberate nods to materials that Roger Dubuis explored extensively in its nascent collections. It is worth noting that Roger Dubuis was among the pioneers in integrating 18k pink gold and mother-of-pearl in men’s watches, a combination that lends this anniversary piece a unique warmth and luxurious character. The watch is presented on a brown calfskin strap, equipped with an interchangeable quick-release system for enhanced versatility, and secured by a matching pink gold folding clasp.
This anniversary release is more than just a reintroduction of a past complication; it integrates modern Roger Dubuis design elements that have become instantly recognizable. These include the distinctive triple-lug case, the sharply fluted bezel, and the meticulously finished double-sided flange, all contributing to a timepiece that is both historically resonant and undeniably contemporary.
The Hommage La Placide: A Fusion of Perpetual Calendar and Biretrograde
Further underscoring the brand’s 30th-anniversary celebrations, the Hommage La Placide presents a more intricate interpretation of Roger Dubuis’ calendar expertise. Limited to a mere 28 pieces, this extraordinary watch masterfully merges a perpetual calendar with a biretrograde display, uniting two complications deeply intertwined with the brand’s early horological explorations. At its heart lies the Poinçon de Genève-certified Caliber RD1472, a remarkable movement that represents a sophisticated hybrid construction. It integrates meticulously restored RD14 base movements, originally introduced in the early 2000s, with the RD72 perpetual calendar module, first developed in 1999.
This innovative fusion reflects Roger Dubuis’ enduring fascination with both the art of watchmaking restoration and the intricate world of complications. The result is a timepiece that not only showcases technical mastery but also pays homage to the brand’s commitment to preserving and evolving its horological heritage. The full calendar information – encompassing the day, date, month, leap year, and moonphase – is presented through a layout that remains consistent with the brand’s signature biretrograde aesthetic, ensuring a cohesive and recognizable visual language.
The Hommage La Placide is housed in a 38mm 18k pink gold case, a size that aligns with the more classical proportions characteristic of Roger Dubuis’ earlier watches. In true Roger Dubuis fashion, the dial features a multi-layered construction. It combines mother-of-pearl segments for the calendar indications with a lacquered “Leman Blue” base, a subtle yet evocative reference to Lake Geneva, the cradle of Swiss watchmaking. A blue aventurine disc provides a celestial backdrop for the moonphase display, while applied gold elements add depth and sophistication. The iconic biretrograde day and date indications are arranged across semi-circular scales that gracefully widen towards the periphery before narrowing towards the center. The watch is completed with a blue leather strap, featuring an interchangeable system for ease of wear, and a matching pink gold buckle, reflecting the brand’s contemporary focus on wearability and user experience.
The Excalibur Grande Complication: A Symphony of Horological Excellence
Representing the zenith of Roger Dubuis’ reinterpretation of calendar complications is the Excalibur Grande Complication. Introduced in 2025 as the brand’s second fully in-house developed grand complication, this limited edition of just eight pieces is a tour de force of horological engineering. It ingeniously combines a perpetual calendar with a minute repeater and an automatic tourbillon, all orchestrated within the complex architecture of the Caliber RD118. The perpetual calendar function itself is presented using the brand’s signature biretrograde display, featuring separate semi-circular arcs for the day of the week and the date. These are complemented by a month disc and a leap year indicator, demonstrating a sophisticated integration of traditional calendar functions.
This configuration builds upon Roger Dubuis’ pioneering work in both perpetual calendars and retrograde systems, uniting these two challenging complications within a single, highly complex movement. The Caliber RD118 is engineered to accurately track the Gregorian calendar without the need for manual correction until the year 2100, a testament to its remarkable precision and enduring functionality. While the addition of a minute repeater and a tourbillon significantly elevates the watch’s overall complexity, the calendar display remains a central element of its design, reinforcing Roger Dubuis’ unwavering dedication to reinterpreting classic complications through its distinctive and bold design lens.
The Excalibur Grande Complication is presented in a substantial 45mm 18k pink gold case, adhering to the more generous proportions typically associated with the Excalibur collection. The dial is masterfully openworked, providing an unobstructed view of the intricate mechanical ballet unfolding beneath. The biretrograde day and date displays are elegantly complemented by the month disc and leap year indicator, strategically positioned along the upper section of the dial. The flying tourbillon, a symbol of haute horlogerie mastery, is positioned between the 5 and 6 o’clock markers, while the minute repeater function is activated via a discrete pusher located on the left side of the case. Visible through the sapphire crystal caseback, the Caliber RD118 is composed of an astonishing 684 individual components, all finished to meet the stringent requirements of the Poinçon de Genève. The watch is paired with a brown calfskin strap, featuring the brand’s interchangeable system, and a refined pink gold pin buckle, ensuring both comfort and style.
