Roger Dubuis Excalibur RDDBEX0545 45mm RD505SQ Tourbillon Watch
The Roger Dubuis Excalibur RDDBEX0545 is a bold 45mm skeleton tourbillon watch that combines complex mechanical architecture with a powerful motorsport-inspired aesthetic. Its titanium case, black rubber strap, and fully openworked dial create an unmistakable high-performance presence on the wrist.
The skeleton dial exposes an intricate network of gears, bridges, and transmission components, turning the mechanical structure itself into the visual centerpiece. Around the 7 to 8 o’clock position, the exposed tourbillon adds continuous motion and depth, while the silver-gray framework, black skeleton elements, and vivid red accents create a striking high-contrast composition.
Red arrow-shaped hands, a red minute track, and a matching red crown enhance the dynamic racing character, while circular outer hour markers maintain clear time readability. The sculpted bezel with oversized numerals and sharp geometric surfaces completes the futuristic look, making this Excalibur a strong choice for collectors who appreciate expressive mechanical design.
