The first ever Roger Dubuis skeletonised automatic movement, code-named RD820SQ, is the star of the show in a fascinating line-up of Excalibur Automatic Skeleton models. Framed by the iconic Excalibur design features expressed through a pleasing variety of materials, this eminently versatile caliber embodies the essence of elegance and refinement conveyed in the language of architectural and technical mechanics. The iconic Excalibur collection by Roger Dubuis features several hand-wound models showcasing its self-assigned mission as the “pioneer of contemporary skeletons” as well as its acknowledged expertise in the realm of tourbillons. Well aware that many mechanical watch fans also appreciate the reliability and convenience of automatic movements, the Manufacture introduced its selfwinding RD820SQ calibre in 2015 comprising 167 individually finished parts.
