About the Excalibur family
Excalibur is Roger Dubuis's main collection, introduced in 2005. It has a round case with a distinctive notched bezel and wide, strong lugs, and it is the home of the brand's skeleton movements, including the star-shaped Astral Skeleton design, as well as tourbillons and other complications.
The references in this catalog include skeleton models with the RD720SQ caliber, in titanium, black-coated titanium, rose gold and white gold. Check the open movement for dust and marks, the condition of the straps and the quick-change system, and the Geneva Seal or other markings against the papers.
