REF. RDDBEX1046


A 45 mm supercar-inspired marvel born from speed and precision. Unveiled at the Goodwood Festival of Speed 2023, this bold timepiece combines lightweight carbon construction with a hyper-resistant ceramic bezel and a notched rubber strap. At its heart beats the new RD780 calibre—a fully integrated flyback chronograph featuring a visible column wheel, a 120° Rotating Minute Counter (RMC), a vertical clutch for enhanced accuracy, and the innovative Second Braking System (SBS) for stable chronograph operation. Skeletonized design elements showcase the movement’s architecture, which is Poinçon de Genève certified, while the open caseback reveals a rotor inspired by supercar wheels. Water-resistant to 10 bar (100 m), this watch perfectly fuses automotive DNA with avant-garde haute horlogerie.
