Roger Dubuis has unveiled the Excalibur The Metamorph Merlin watch as the final piece in the Knights of the Round Table trilogy
For more than a decade, Roger Dubuis has reimagined the Arthurian legend through its Knights of the Round Table creations. Each trilogy has explored a different chapter of this universe through refined métiers d’art, architectural displays and uncompromising mechanical expertise. The fourth book of the saga is dedicated to Merlin, the legendary wizard, prophet and advisor whose wisdom shaped the destiny of King Arthur and the Round Table.
Following the Omniscient Merlin in 2024, which celebrated the sorcerer’s all-seeing wisdom, and the Enchanter Merlin in 2025, dedicated to his mystical powers, Roger Dubuis has now unveiled the final chapter of the trilogy: the Metamorph Merlin. 
Paying tribute to Merlin’s extraordinary ability to shapeshift, this new creation draws on the symbolism of the mythical white stag, representing transformation and the passage between the visible and invisible worlds. It explores a new facet of Merlin’s legend while transforming ancient mythology into a contemporary work of haute horlogerie.
Inspired by the mythical forest where Merlin is said to have assumed multiple forms, and where the Lady of the Lake is believed to dwell, the dial transforms Arthurian symbolism into an architectural landscape. Building on the distinctive hexagonal language introduced in the first chapter – which was inspired by the basalt columns of the Giant’s Causeway – this latest composition recreates a dense forest through layered geometry and deep green tones.
Limited to just 28 pieces, the Roger Dubuis Excalibur the Metamorph Merlin is composed of 57 individually crafted blocks, the dial combines green CVD-coated elements, polished pink gold, transparent glass and crystalium to create depth, texture and shifting reflections. Each block is positioned at a different height, forming a three-dimensional composition. Rather than literally depicting a forest, Roger Dubuis recreates its atmosphere through architecture, materials and light. 
The watch features an automatic Calibre RD821, which has been engineered to accommodate the three-dimensional architecture of the dial while preserving the balanced proportions of the maison’s signature Excalibur case. The 45mm pink gold case is completed by a sapphire crystal that reveals the dial’s sculptural landscape from multiple perspectives. On the reverse is the skeletonised 360° oscillating weight, which is inspired by the stained-glass windows of medieval castles.
Further celebrating Roger Dubuis’s savoir-faire, the case is hand engraved to represent Merlin and houses the 12 emblematic micro-sculpted knights.
