The latest Roger Dubuis innovation to emerge from an exclusive collaboration with Pirelli, Excalibur Spider Pirelli shows what happens when the finest minds from different industries come together to share their unrivalled know-how, breakthrough research and boundless creativity. Inspired by the renowned motorsport Pit Stop, each element of the new Excalibur Spider Pirelli is interchangeable, from strap to crown and bezel – all with a simple click. With a calibre that includes Roger Dubuis' first automatic skeleton, the transparent view of its self-winding movement is held directly on the inimitable Roger Dubuis star. It also features a micro-rotor, one reduced to its strict essence at 11 o’clock, turning seamlessly with that of the wrist.
