For Watches & Wonders Geneva 2026, Roger Dubuis turns back to one of the signatures most deeply entwined with its identity: the biretrograde display. Long before the maison’s more extrovert expressions came to define its modern image, this was one of the ideas that established Roger Dubuis’ own watchmaking language — technically intelligent, visually dynamic and infused with a sense of play that never came at the expense of seriousness.

This year, that legacy is reasserted through two new calendar watches that approach the complication from different directions. One is a sport-chic steel day-date in Cosmic Blue, the other a more elevated perpetual calendar in pink gold with astronomical moonphase.

Excalibur Biretrograde Calendar

The Roger Dubuis Excalibur Biretrograde Calendar pairs its Cosmic Blue dial with a 40mm steel case and integrated bracelet for a sport-chic expression of the complication

The Excalibur Biretrograde Calendar is the more direct and immediate of the novelties, though no less central to the story Roger Dubuis wants to tell this year. Housed in a 40mm steel case, it takes the maison’s patented biretrograde display and places it in a format that feels sporty, contemporary and assured. The new Cosmic Blue dial, with its layered construction, gives the watch more depth than a straightforward calendar model might initially suggest. Roger Dubuis has long understood that mechanical identity is only half the equation; the other half lies in how that mechanics is staged. The seven-level dial, shifting finishes and open-worked elements all contribute to a watch that feels alive on the wrist. Behind it is the automatic RD840 calibre, visible through the sapphire caseback and finished to meet the demands of the Poinçon de Genève.

Excalibur Biretrograde Perpetual Calendar

A closer look at the Roger Dubuis Excalibur Biretrograde Calendar reveals the moonphase display set beneath the twin retrograde scales, framed by layered blue textures and exposed mechanics

The Excalibur Biretrograde Perpetual Calendar is the more stately release of the pair: a 40mm pink gold watch that combines the maison’s hallmark day-and-date biretrograde display with one of high watchmaking’s most exacting complications. The new RD850 calibre is central to that proposition. Developed in-house, it advances Roger Dubuis’ perpetual calendar architecture with the addition of a month corrector for easier adjustment, while integrating an astronomical moonphase at six o’clock that will remain accurate for around 122 years before requiring correction. The Astral Blue colourway, mother-of-pearl indications, aventurine moonphase display and domed pink gold moon create a dial that feels expansive rather than dense, as though the complication has been opened up and given room to breathe. Add the Poinçon de Genève and the movement’s inner angle finishing, and what emerges is a watch that feels true to Roger Dubuis in the most meaningful sense: expressive, technically serious and entirely unwilling to separate performance from spectacle.
