The Roger Dubuis Excalibur Spider Huracán RDDBEX0829 is a striking timepiece born from the collaboration between the Swiss watchmaker and Lamborghini Squadra Corse. This 45mm watch features a black DLC (Diamond-Like Carbon) titanium case with a titanium container and rubber inlays, offering both durability and a lightweight feel. The black DLC titanium bezel, adorned with lacquered markings, complements the overall design, while the sapphire crystal with anti-reflective coating ensures clarity. The open case back, also in black DLC titanium, showcases the metallized Excalibur Huracán logo, providing a glimpse into the intricate mechanics within. The black rubber strap with black Alcantara® inlay and black stitching enhances comfort and style, and is easily interchangeable thanks to the Quick Release System (QRS).

At the heart of this timepiece lies the RD630 calibre, an automatic, self-winding movement developed specifically for the partnership with Lamborghini Squadra Corse. Inspired by automotive engineering, the calibre's structure resembles a supercar engine, featuring strut-bars that form a distinctive visual signature. The rotor is designed to mimic a supercar wheel rim, further emphasizing the automotive inspiration. With a twin barrel power supply, the movement achieves a power reserve of 60 hours. The dial includes a lower flange with transferred texts and minute tracks, and an upper flange with screw-like hour markers that are PVD coated and filled with Super-LumiNova (SLN) for enhanced legibility. This fusion of high horology and automotive aesthetics makes the Excalibur Spider Huracán RDDBEX0829 a remarkable example of innovative design and engineering.
