Roger Dubuis Completes A Trilogy Of Merlin-Inspired Knights Of The Round Table Watches

This is the third and final time Roger Dubuis is riffing on the theme: a watch inspired by the Arthurian legend of the magician Merlin, told through a fascinating dial construction. Like The Omniscient Merlin of 2024 and The Enchanter Merlin of 2025, this new timepiece has a dial consisting of 57 hexagonal blocks of varying materials, finish types, and levels. It is a structure inspired by the basalt columns of the rugged Giant’s Causeway in Northern Ireland; when reproduced on a dial measuring 45mm across, the effect is one of uncommonly complex verticality.

Omniscient Merlin had a moody black dial with gold highlights. Enchanter Merlin was largely white, set off with crystalline shimmer. The new Excalibur Knights of the Round Table The Metamorph Merlin, as it is fully known, has gone green instead—a rich, verdant shade expressed through CVD coating. The odd block is in polished pink gold: some are transparent glass, while others, set further down in the dial, sparkle with green metal crystals. It evokes a forest, full of shadows and light, as the specific part of the legend referenced is Merlin’s ability to shapeshift between human and animal forms. For the first time, said legend is extended outside the dial—the pink gold case is hand-engraved, with Merlin depicted in micro-relief as both a bearded wizard and as a stag on the crown side.

And then, there are, of course, the titular knights. They are part of the hand engraving on the other side of the case, but also within. Twelve of them, one for each hour, are employed around the dial in pink gold, standing six millimetres tall in a display of micro-sculpting and painstaking hand finishing. Each has his own armour, weapon, and pose, reflecting their varied personas. The case thickness is 16.8mm, to accommodate all this artistry; a sapphire band underneath the Excalibur’s signature notched bezel lets light in through the case middle, as well as providing an additional viewing angle.

Through the display caseback, one spies the 360° oscillating weight, which takes after medieval stained glass windows. The two-hand Calibre RD821 was specifically designed to accommodate the three-dimensionality of the dial, and is hand-finished according to the demanding standards of the Poinçon de Genève certification—one that so many of Roger Dubuis’ haute horlogerie offerings can boast. The watch is limited to just 28 pieces.
