Roger Dubuis has had a longstanding partnership with Italian automaker Lamborghini, its racing team, Lamborghini Squadra Corse, and its official tyre provider, Pirelli. And over the years many a unique timepiece featuring striking horological-automotive design synergy have come out of this partnership. Notable among is the Excalibur Spider Huracán collection, equipped with an in-house movement and a distinctive design.

While the previous version of the Excalibur Huracán had a 45-mm titanium case, the latest one uses CCF, or Ceramic Composite Fiber, a high-tech material Roger Dubuis developed, and is 20 per cent lighter than carbon. The material used is similar to the ceramic fibers that are used in aerospace in the production of space rockets. White varnished lower flange with transferred texts and minute track. Rhodium plated upper flange with polished and Rhodium plated hour markers filled with SLN in the centre.

The dial features white gold hour and minute hands with black outlined tips filled with Super Luminova, and black varnished second hand.

The strap of the new watch is made of luminescent rubber, vulcanized with Super Luminova which is also applied on the bezel and the strut bars. The strap gets a Pirelli Cinturato pattern on its lining , and is interchangeable thanks to a Quick Release System.

The in-house Caliber RD630 is heavily skeletonized like most modern Roger Dubuis calibers, and has a 12º tilted balance wheel, an innovation first used by the brand in its eye-popping Quatuor timepiece (which actually had four of them) in 2014; a honeycomb structure reminiscent of Lamborghini grilles built into the mainplate; and a hexagonal date window at 6 o’clock with distinctive speedometer-style numerals. The inclined sprung balance has been repositioned at 12 o’clock for maximum exposure on the front of the openworked dial, along with a new strut-bar-shaped bridge that echoes those on the V10 engine of the Huracan “supercar” for which this model is named. Despite the watch’s overall openness, the date disk is designed to remain hidden except for the current date numeral in the hexagonal aperture at 6 o’clock (the hexagon is a shape found often in Lamborghini design). As in this movement’s predecessor, it has a 360º central rotor inspired by a Huracan’s wheel rim, whose spinning effect brings to mind the wheels of a racecar at high speeds.
