Roger Dubuis Excalibur Sorayama MB Limited Edition

Hyper luxury Swiss watch manufacture Roger Dubuis has created a limited edition Excalibur Monobalancier timepiece in collaboration with world-famous Japanese artist Hajime Sorayama.

Limited to 28 pieces, this Poinçon de Genève certified timepiece is presently available in Japan only. This 42mm timepiece in titanium is equipped with a modern Roger Dubuis mechanical skeleton movement.

The skeleton calibres manufactured by Roger Dubuis in Geneva are the essence of the expressive singularity of the Excalibur collection. Every single component being finished by hand, the watches are symbols of passion.

Developed for the new generation Excalibur watches, the Roger Dubuis Calibre RD720SQ comes with improved performances. It offers an increased power reserve up to 72 hours thanks to a new gear train toothing and escapement optimization through its geometry. Improved durability thanks to new lube, and increased precision thanks to 4hz frequency.

The new Roger Dubuis Excalibur Monobalancier watch created in partnership with Hajime Sorayama mixes both creative territories of the artist and the brand.

Hajime Sorayama is known worldwide for his works in fine art, illustration and industrial design. His notable works include the initial design of first generation of Sony AIBO robots and the pin-up works for men’s magazines like Penthouse.

The star-shaped bridge redesigned by Sorayama, turns curvy and full polished, same as the titanium case and bracelet, like an echo of his metallic 3D sculptures. The micro rotor displays a moiré effect, with a fixed fringed sapphire glass and a mobile engraved metallic part, to remind the artist’s obsession about light reflection.

The white lacquered box is adorned with hot-stamped Roger Dubuis with Sorayama font.

The Excalibur Sorayama MB watch comes with a polished titanium bracelet. It is the first Roger Dubuis grade 5 titanium bracelet to feature its Quick Release System.
