The Excalibur collection captures the spirit of avant-garde Fine Watchmaking that defines Manufacture Roger Dubuis, to the point that it is now an icon of the brand. With its powerful design and superlative mechanical movement, the Excalibur Self-Winding Flying Tourbillon with micro-rotor in white gold continues in this vein.
Its imposing 45mm diameter leaves no doubt that this is a watch with character. With its frank lines, robust crown-cover and signature indented bezel, the Excalibur Self-Winding Flying Tourbillon completes a line already rich in exceptional movements.
This Excalibur model incorporates the Calibre RD520, a self-winding flying tourbillon movement with visible micro-rotor. This spectacular movement, which offers a new degree of exposure to this type of complication, has been designed, developed and produced by Manufacture Roger Dubuis. Rhodium-plated with Côtes de Genève decoration and assembling 227 components, the Calibre RD520 is hallmarked with the prestigious Poinçon de Genève. It proposes hour and minute functions, and the tourbillon can be seen in an aperture at 7 o’clock.
Water-resistant to 5 BAR (50 metres), this Excalibur Self-Winding Flying Tourbillon with micro-rotor in white gold is presented on a black alligator strap with an adjustable folding buckle, also in white gold.
This exceptional timepiece is proposed as a limited edition of 88.
