This Roger Dubuis Excalibur Spider Pirelli (Ref. RDDBEX0826) is a high-octane collector’s dream, born of the Maison’s 2021 collaboration with Pirelli and limited to just 88 pieces. Its 45 mm black DLC‑coated titanium case houses the first automatic skeleton movement from the brand, the Geneva‑Seal‑certified RD820SQ with micro‑rotor and 60‑hour power reserve. The openworked dial, held together by the signature star‑shaped bridge, offers a dramatic view into the finely finished NAC‑coated bridges and circular‑grained mainplate. The innovative Quick‑Release System allows rapid interchange of bezel, crown and strap, the latter featuring real Pirelli racing‑tire rubber inlays with the iconic Cinturato pattern. With 50 m water resistance and a bold motorsport aesthetic, this piece stands at the intersection of avant‑garde engineering and haute horlogerie, making it a standout for seasoned collectors.
