Roger Dubuis Excalibur Lady of the Lake Grey

Why It Matters

• The Roger Dubuis Excalibur Lady of the Lake Monobalancier Grey is a 36mm rose gold women’s timepiece housing automatic calibre RD830 and featuring a Sovereign Grey multi-layer dial inspired by Viviane, the Lady of the Lake and guardian of the Excalibur sword in Arthurian legend.
• The fluted bezel carries 48 diamonds of exceptional clarity, while the dial combines white mother-of-pearl, dark rhodium plating, and rose gold sword-shaped hands.
• Calibre RD830 is certified by Poinçon de Genève and features a 22k gold open-worked oscillating weight visible through a sapphire caseback.
• The Sovereign Grey alligator strap with a pearled effect is interchangeable, fitted with a rose gold pin buckle.

Roger Dubuis has spent over two decades building a watchmaking identity around the legend of King Arthur. The 2026 Excalibur Lady of the Lake is significant because it redirects that mythology entirely: for the first time, the focal point is not Arthur or his knights, but Viviane, the woman who held Excalibur all along.

The Story Behind It

Viviane rules an underwater kingdom concealed within the Brocéliande forest, crossing between visible and invisible worlds at will.

In the Arthurian canon, she is no passive guardian. She educated Merlin in his own magic and ultimately surpassed him. She raised Lancelot in her kingdom, shaping the chivalric ideal he would carry into Arthur’s court. And she kept Excalibur beneath the lake until Arthur proved himself worthy of receiving it, a political act as much as a mythological one. Roger Dubuis draws on this agency directly: the Sovereign Grey of the dial is described not as a decorative choice but as armour, transmitting courage, independence, and strategic clarity. The colour reference runs from the dial through to the alligator strap, giving the piece a considered coherence that extends well beyond aesthetic coordination.

Design and Mechanics

The dial architecture rewards close reading, with each layer carrying a distinct material logic.

At the centre sits a heart of white mother-of-pearl enclosed in gilded brass, iridescent against a surrounding dark rhodium-coated plate with a sunray finish. A small seconds counter at 6 o’clock, decorated with a snailed effect, anchors the lower register. The hour and minute hands in rose gold are crafted in the form of swords, reinforcing the Arthurian reference without overstating it. The two-sided flange at the outer edge carries snailed and sunray surfaces with diamond-cut finishes, producing a contrast that the Maison attributes directly to Viviane’s dual nature. Three-dimensional indexes receive a rose gold galvanic treatment, set against the dark rhodium background for depth.

The 36mm rose gold case is designed to read as a jewel in its own right. Polished angles play against brushed satin-finished surfaces; the crown is ring-shaped and transparent-lacquered over the Roger Dubuis logo. Calibre RD830, visible through the sapphire caseback, comprises 183 components and displays Côtes de Genève finishing on the main plate alongside the snailing detail repeated from the dial. The 22k gold open-worked oscillating weight is a statement of finishing conviction in a movement that will, for most wearers, remain unseen during daily wear.

On the Wrist

At 36mm, the Excalibur Lady of the Lake occupies a scale that suits both formal and cultural contexts across the GCC.

The Sovereign Grey alligator strap with its pearled effect is interchangeable, a practical consideration for collectors who rotate straps to suit occasion. The rose gold pin buckle maintains material consistency with the case. For collectors in the region who follow the presentation calendar at Watches and Wonders, this piece fits a broader pattern of maisons addressing a GCC feminine collector who expects mechanical conviction alongside jewellery-grade execution. Brands such as Chopard and Piaget occupy adjacent territory; Roger Dubuis differentiates through the specificity of its narrative programme and through Poinçon de Genève certification on every movement it produces.

Where It Sits in the Collection

The Excalibur Lady of the Lake extends a line that has been in continuous development since 2013, when the Knights of the Round Table collection first turned dials into micro-sculptural scenes.

That series established a format: Arthurian subjects rendered in three-dimensional watchmaking layers, each dial a distinct episode rather than a decorative motif. The Lady of the Lake advances that logic by changing the narrative voice. Previous chapters centred on Arthur’s court; this one centres on Viviane, whose role in the saga is arguably more consequential. For collectors building a position in Roger Dubuis, the piece represents the Maison’s intent to develop its mythological programme across gender lines, with the same technical rigour applied throughout. Mechanical legitimacy, as the press release frames it, is non-negotiable: automatic movements with Geneva certification belong in feminine timepieces as naturally as in any other.
