World Premiere: Roger Dubuis Excalibur Quatuor



Geneva watchmaker Roger Dubuis has just unveiled the Excalibur Quatuor, the first timepiece encased in light-weight silicon, at the 23rd Salon International de la Haute Horlogerie (SIHH).

According to Roger Dubuis, "Silicon has been chosen for its uniquely low weight and its incomparable hardness. In fact, it is half the weight of titanium, which is half the weight of steel, yet it is 4 times harder."

The rare and exquisite timepiece, played by four virtuosi, is symbolised by the four elements, Water, Fire, Air, and Earth, and presents the ultimate challenge to gravity. Besides silicon, the Excalibur Quatuor is also available in a 18K rose gold case.
