Roger Dubuis Excalibur Spider Huracàn “Frosty White” Automatic Limited Edition

Limited to just 88 pieces, the new Excalibur Spider Huracán is the latest creation to emerge from Roger Dubuis x Lamborghini Squadra Corse, a partnership defined by radical performance and razor-sharp aesthetics. Made of Ceramic Composite Fibre (CCF), this racing car inspired type has a striking frosty white case.

Equipped with an automatic RD630 calibre, the 45-mm diameter Excalibur Spider Huracán channels the same exhilarating blend of performance and lightness as its motoring namesake.

Taking strong visual cues from which the Lamborghini Huracán is based, the timepiece is imbued with signature racing design codes. With a honeycomb motif made famous by the supercar, the hexagonal dashboard of the Lamborghini Huracán is reflected in the timepiece, the same epicentre paralleled in the shape of the calibre.

Its twin barrels and a 12° tilted balance wheel represent the movement signature associated with Lamborghini Squadra Corse. When viewed from the back, the semi-skeletonised movement reveals the 360° oscillating rim weight, which evokes a Huracán wheel rim. This movement provides a power reserve of 60 hours.

The titanium crown is inspired by the supercar’s racing nuts. It is paired with an upper calibre strut-bar design bridge reminiscent of those found on the Lamborghini Huracán V10 engine itself. A cryptical date feature enhances its playful allure, while a Quick Release System on the buckle and strap ensures the watch is easily interchangeable.

CCF (Ceramic Composite Fiber) is a high-tech material exclusive to Roger Dubuis. The Geneva manufacture developed this material offering a significant gain in weight with CCF being 20% lighter than carbon. Ceramic fibers are used in aerospace in the production of space rockets.

Both the upper flange and hands of the timepiece are filled with Super-Luminova™. The strap of the watch is made of luminescent rubber. Using a manufacturing process known as SuperBiwiNova®, the rubber is vulcanized with SLN. Luminescent material – SLN – is also applied on the bezel and the strut bars. Thanks to these innovative luminscent applications, the Excalibur Spider Huracán offers a stunning visual treat by night.

SuperBiwiNova® is a technology developed by Switzerland based company BIWI SA.
