Time's Dance: Roger Dubuis' Calendar Innovations Unveiled

Excalibur Biretrograde Calendar: A Harmonious Blend of Heritage and Modernity

The Excalibur Biretrograde Calendar, launched to commemorate Roger Dubuis' 30th anniversary, exemplifies the brand's distinctive approach to calendar indications. This timepiece revives the biretrograde display, a co-patented system developed by Roger Dubuis and Jean-Marc Wiederrecht in the late 1980s, which was a defining feature of the brand's inaugural watches. The watch displays the day and date across two semi-circular scales, with the hands elegantly sweeping back to their starting positions after each cycle. This intricate mechanism provides a display that is both easy to read and visually striking. Encased in a 40mm 18k pink gold case, the watch's dimensions echo the more understated styles of the brand's earlier collections. It is powered by the in-house automatic Caliber RD840, boasting a 60-hour power reserve and certified by the prestigious Poinçon de Genève. The dial features ecliptic counters for the day and date, complemented by a small seconds sub-dial at 6 o'clock and the Biretrograde Calendar inscription at 12 o'clock. The luxurious combination of pink gold and mother-of-pearl, a pairing Roger Dubuis pioneered in men's watches, is further enhanced by a brown calfskin strap with a quick-release system and a matching pink gold folding clasp, ensuring both elegance and wearer convenience. While drawing inspiration from historical designs, the Excalibur Biretrograde Calendar seamlessly incorporates contemporary Roger Dubuis design signatures, including the distinctive triple-lug case, fluted bezel, and signed double-sided flange, making it a true synthesis of past and present.

Hommage La Placide: Merging Perpetual Sophistication with Retrograde Flair

The Hommage La Placide, also introduced for Roger Dubuis' 30th anniversary and limited to just 28 pieces, presents an even more sophisticated interpretation of calendar complications. This watch ingeniously combines a perpetual calendar with the brand's signature biretrograde display, uniting two cornerstones of Roger Dubuis' early innovations. At its heart lies the Caliber RD1472, a Poinçon de Genève-certified movement that integrates meticulously restored RD14 base movements from the early 2000s with the RD72 perpetual calendar module, initially developed in 1999. This hybrid construction showcases Roger Dubuis' ongoing dedication to both the art of horological restoration and the pursuit of complex mechanisms. The full calendar, including day, date, month, leap year, and moon phase, is presented in a layout consistent with the brand's distinctive biretrograde aesthetic. The watch is housed in a refined 38mm 18k pink gold case, reflecting the classical proportions favored in the brand's foundational timepieces. The dial features a multi-layered construction, with mother-of-pearl calendar segments set against a lacquered "Leman Blue" base, a subtle nod to Lake Geneva. A blue aventurine moon phase display and applied gold elements add further visual depth and luxury. The iconic biretrograde day and date indicators are arranged on semi-circular scales, widening at the periphery and narrowing towards the center, creating a dynamic visual effect. A blue leather strap with an interchangeable system and a pink gold buckle completes the ensemble, underscoring the brand's contemporary focus on adaptability and comfort.

Excalibur Grande Complication: The Pinnacle of Horological Ingenuity

The Excalibur Grande Complication represents Roger Dubuis' most elaborate foray into calendar watchmaking. Unveiled in 2025 as the brand's second entirely in-house grand complication, this limited-edition timepiece, restricted to eight examples, masterfully integrates a perpetual calendar, a minute repeater, and an automatic tourbillon within its Caliber RD118. The perpetual calendar itself is presented through the brand's distinctive biretrograde display, featuring individual semi-circular scales for the day of the week and date, alongside a month disc and leap year indicator. This intricate configuration builds upon Roger Dubuis' pioneering work in both perpetual calendars and retrograde systems, uniting these functions within a single movement capable of accurately tracking the Gregorian calendar until 2100 without manual adjustment. While the inclusion of a minute repeater and tourbillon significantly elevates the watch's overall complexity, the calendar display remains a central element of its design, emphasizing the brand's enduring commitment to reinterpreting traditional complications with its unique artistic vision. The Excalibur Grande Complication features a robust 45mm 18k pink gold case, characteristic of the Excalibur collection's bold proportions. The dial is intricately openworked, providing an unobstructed view of the complex mechanics, with the biretrograde day and date displays, month disc, and leap year indicator prominently positioned in the upper section. A flying tourbillon is elegantly situated between 5 and 6 o'clock, and the minute repeater is activated via a pusher on the left side of the case. The Caliber RD118, comprising 684 components and finished to the exacting standards of the Poinçon de Genève, is visible through the sapphire caseback. A brown calfskin strap, equipped with an interchangeable system and a pink gold pin buckle, completes this magnificent timepiece.
