Roger Dubuis - Excalibur Automatic Skeleton

Roger Dubuis Excalibur Automatic Skeleton

This new timepiece, to be unveiled at the SIHH 2015, houses Roger Dubuis first skeletonised automatic movement with micro-rotor.

At the SIHH 2015, Roger Dubuis will be presenting two skeleton-work Excalibur creations:  the Excalibur Automatic Skeleton and the Excalibur Spider Skeleton Flying Tourbillon. We focus today on the former.

In addition to its multiple motivations for pursuing its victorious vanguard charges into the skeletonwork kingdom, Manufacture Roger Dubuis finds in these impressive feats of miniaturisation – much like its ground-breaking micro-rotor also featured in this model – the opportunity to reveal the prestigious finishes that earn it 100% Poinçon de Genève certification. All faces of the 167 parts composing the new in-house RD820SQ automatic skeleton calibre are individually finished. Despite the constraints naturally entailed by the automatic movement, the Excalibur Automatic Skeleton maintains its architectural and powerful design.



The 42mm pink gold case and bezel frame a spectacular 3D effect created by raising the famous skeleton ‘star shape’ and playing with the height of the openworked micro-rotor. The latter embodies a classic paradox of the kind that Roger Dubuis loves to explore, since the weight of a micro-rotor is generally considered a positive aspect and skeletonising it would thus appear counter-intuitive in technical terms. In 2005, Roger Dubuis did away with the central rotor while achieving equivalent winding power; and ten years later, in 2015, it rolls out the first skeletonised automatic Roger Dubuis movement with micro-rotor.

Once again displaying an optimal command of technical and aesthetic parameters, including by lavishing meticulous expertise on the gear wheels and finishes; maintaining the transparency of skeleton-work despite the self-winding train and the micro-rotor, while achieving sufficient winding power: the Excalibur Automatic Skeleton once again display the Warrior mind-set in every sense of the term.



The brand

With remarkable dynamism, Roger Dubuis quickly ignited the world of Haute Horlogerie and has developed over thirty completely original in-house movements.
