SIHH 2009: Roger Dubuis Double Tourbillon Excalibur Squelette Watch

Since its introduction, the Roger Dubuis Double Tourbillon Excalibur watch has stood as one of the most visually captivating implementations in haute horlogerie. In 2009, the Geneva manufacture reveals a skeleton variation of its powerful Excalibur watch, whose intricate hand-finished tourbillon movement reveals its full secrets through the delicate art of open working.

The magisterial rose or white gold case of the Roger Dubuis Double Tourbillon Excalibur Squelette watch measures 45mm in diameter; exceptional attention to finishing, and a number of striking details--among them a hinged crown protector and a crenelated bezel--enhance presence both on and off the wrist. It is also an ideal frame for the manually-wound movement, whose intricate structure of 292 pieces is supported by skeletonized bridges treated with black rhodium. The twin flying tourbillons with a differential rotate in opposing directions, completing full revolutions every 60 seconds. Balance frequency is 21,600 alternations per hour, and power reserve is 48 hours. All steel components, including the keyless works and the carriages of the tourbillons, are finely beveled in accord with the traditional Genevois norms for watchmaking of the highest level.

Sapphire crystals are featured on both the front and back of the Roger Dubuis Double Tourbillon Excalibur Squelette watch. A luxurious strap in crocodile leather and an engraved "RD" deployant clasp in 18-karat gold match the exceptional character of this model, which is water resistant to 50 meters.
