The Roger Dubuis Excalibur Spider Monobalancier Huracan DBEX1008 is a limited edition of 88 pieces and a clear example of the brand's motorsport-led design. Introduced around 2024, it continues Roger Dubuis's partnership with Lamborghini Squadra Corse, with a case and movement layout that echo the look of modern supercar engineering. The 45 mm titanium case is fitted with a white mineral composite fibre bezel, a combination that keeps the watch light while giving it a distinctly technical look. The skeletonized dial reveals the automatic caliber RD630, a manufacture movement with an automotive-inspired design and a rotor modeled after a Lamborghini wheel. At 12 o'clock, the tilted balance remains one of the watch's most recognizable features. The movement also has twin barrels and a 60 hour power reserve. Despite its openworked construction, the watch retains straightforward time and date functionality. The contrast between the dark titanium case architecture and the bright composite bezel gives the DBEX1008 a bolder look than most high-end sports watches, while still feeling firmly in line with the modern Excalibur collection. For collectors drawn to contemporary watchmaking, limited production, and the Roger Dubuis-Lamborghini collaboration, the DBEX1008 is a strong entry in the Huracan series.
