Roger Dubuis Excalibur Lady
of the Lake (DBEX1193):
Rose Gold, Diamonds and a New 36mm Case
The Roger Dubuis Excalibur Lady of the Lake is one of the most refined debuts of the year. Unveiled at Watches and Wonders 2026, reference DBEX1193 introduces a dedicated 36mm rose gold case, a diamond-set fluted bezel and a layered Sovereign Grey dial. It is haute horlogerie designed with the presence of fine jewellery.
Here is a closer look at the watch, its specifications, and what makes it worth your attention.
From the embossed caseback to the engraved rubber strap, every
detail of this watch pays homage to the high-octane world of racing.
It's not just a watch—it's a statement of performance, precision, and
cinematic style.
A jewel-shaped 36mm case in 18K rose gold
Roger Dubuis created a dedicated case for this piece, the first Excalibur to arrive in a 36mm format. Cut in 18K rose gold and standing 9.85 mm thick, it is shaped like a jewel, with polished angles set against satin brushed surfaces so the gold catches the light from every direction.
The proportions are the headline. At 36mm, the Excalibur Lady of the Lake sits beautifully on a smaller wrist while retaining the architectural presence the collection is known for.
The diamond-set fluted bezel
The maison's signature fluted bezel is set with 48 diamonds totalling around 0.62 carats, framing the dial without ever competing with it. Each of the two inclined lugs carries four additional diamonds, extending the sparkle down the sides of the case.
Even the crown has been reconsidered. Shaped like a ring, it is finished with a transparent lacquer over the engraved Roger Dubuis logo, a detail most brands would leave plain.
The Sovereign Grey dial explained
The dial is the most distinctive element of the watch. At its centre sits a heart of white mother-of-pearl, framed in gilded brass, glowing with a soft iridescence that shifts with the light.
Around it, a dark rhodium plate with a sunray finish adds depth and contrast, while applied rose gold markers keep the time effortlessly legible. A small seconds counter at 6 o'clock, finished with a delicate snailed effect, brings quiet balance to the composition. The result is a dial that is luminous at the centre and shadowed at the edges.
Inside: the RD830 automatic calibre
Powering the Excalibur Lady of the Lake is the automatic RD830 calibre, visible through the sapphire caseback. Built from 183 components, it carries a 22K rose gold rotor and refined finishing throughout, including Cotes de Genève across the movement.
It is the kind of detail that rewards a second look, long after the diamonds have caught your eye. The watch is completed by a Sovereign Grey alligator strap with a pearled effect and a rose gold pin buckle, and is water resistant to 30 metres.

The name behind the watch
The Excalibur collection has long drawn on the legend of King Arthur. This chapter takes its name from the Lady of the Lake, guardian of the sword, and the Sovereign Grey palette is a nod to armour and to the blade itself. It gives the watch its character without ever overshadowing the craftsmanship.
Why the Excalibur Lady of the Lake stands apart
This is a watch that pairs serious haute horlogerie with genuine artistry, and does so in a wearable 36mm case. The diamond-set bezel, the layered mother-of-pearl dial and the hand-finished movement make it a compelling choice for a collector who wants craftsmanship and elegance in equal measure. For anyone exploring Roger Dubuis in Dubai, it is one of the standout releases of 2026.
