Roger Dubuis launches Excalibur Spider Skeleton Flying Tourbillon with Gem-Set Rubber Bezel
May 7, 2015: Manufacture Roger Dubuis has introduced a new Excalibur Spider concept, comprising fresh expressions of its decidedly different interpretations.
Technical, with sporty rubber and ‘forever’ precious diamonds coming together, this watch comes with a rubber bezel framing a diamond-set dial. The physical difficulties in actually setting the gems on an elastic material such as rubber meant that this hadn’t been successfully attempted – until now with this model.
The black-treated RD505SQ movement, the DLC-coated titanium case and flange provide a perfect total-black backdrop on which to ‘paint’ the rubber bezel with a stunning line up of 60 baguette-cut diamonds totalling approximately 2 carats.
On this 88-piece limited edition, the precious stones are actually set into the rubber moulding over the metal bezel, calling for perfect mastery of the exact thickness and a technique based on plastic deformation. Two years of research, undertaken by the Geneva-based gem-setting specialist Pascal Vincent Vaucher, were devoted to this astonishing technical feat and a “Soft Stones in the Sky” patent has been registered to protect this development.
