Actor Lewis Tan spotted wearing a Roger Dubuis

Lewis Tan, the British-Chinese actor and martial artist best known for his roles in 'Wu Assassins,' 'Mortal Kombat,' and 'Into the Badlands,' was recently spotted on the wrist with the Roger Dubuis Excalibur Monobalancier in 18-carat rose gold, reference RDDBEX0698 — a piece that sits firmly at the intersection of Geneva finishing tradition and theatrical watchmaking.

The RDDBEX0698 measures 45mm in rose gold and houses the caliber RD505SQ, a manually wound, in-house skeletonized movement that operates at 21,600 vph and delivers a power reserve of approximately 60 hours. The defining technical feature is the mono-balancier architecture: a single, cantilevered balance wheel suspended on a flying bridge with no conventional cock, giving the escapement an almost architectural visibility when viewed through the open dial. Every component is finished and hallmarked under the Poinçon de Genève — one of the strictest quality certifications in Swiss watchmaking — meaning each part meets exacting standards for anglage, polishing, and beveling before assembly.

The Excalibur line has been Roger Dubuis's flagship collection since its introduction in the early 2000s, and the Monobalancier variant represents a purist statement within that range. Where many skeletal Roger Dubuis pieces lean into multi-axis tourbillons or double flying tourbillons, the Monobalancier strips the concept back to a single, perfectly executed complication, letting the hand-finishing carry the weight. The rose gold case and black leather strap give RDDBEX0698 a warm, wearable character without sacrificing any technical credibility.

For Tan, the choice reads coherently. His public persona is built around disciplined physicality and a certain visual boldness — qualities that map naturally onto a 45mm skeletonized statement piece. Roger Dubuis has historically cultivated an audience with an appetite for visibility and craftsmanship in equal measure, and its Excalibur pieces show up regularly on athletes and entertainers who understand watchmaking rather than merely accessorizing with it.

On the secondary market, the RDDBEX0698 trades at a modest premium or close to list depending on condition and provenance, reflecting solid but not speculative collector demand. Roger Dubuis rose gold skeleton references have held value reasonably well as the brand's Geneva Seal positioning continues to resonate with technically minded buyers.
