Haute Horlogerie aficionados the world over now know to expect the unexpected from Roger Dubuis. For some years now, the Maison has been drawing inspiration from other avant-garde industries, an approach that has resulted in an iconic alliance with supercar designers Lamborghini Squadra Corse. In particular, the Excalibur Aventador S, powered by the iconic RD103SQ calibre in a ceramic composite fibre (CCF) and titanium case, was the first horological expression of this partnership. Now the timepiece viener proposed in a snow-white colour for a limited edition of only 8 pieces, available exclusively online and featuring a series of easily identifiable design elements borrowed directly from its alter ego on four wheels: two 45-degree inclined spiral balance wheels, domed bars, a power reserve reminiscent of elements from the world of racing and an Alcantara strap, plus the world premiere use of ceramic composite fibre. This innovative material weighs 20% less than carbon and is the result of a manufacturing process developed by Roger Dubuis. The resin, used in the aerospace industry as a heat shield and used here in combination with the extremely tough ceramic, is one of the hardest materials in existence. Like every model coming out of the Geneva Manufacture, the exclusive Excalibur Aventador S offered online, with its spectacular architecture, grey accents and white structure, will undoubtedly thrill even those most accustomed to the brand's "surprises". This must-have timepiece, with its clean and decisive lines, is dedicated to an exclusive tribe that lives life to the fullest and is proof that Roger Dubuis never ceases to reinvent the game by proposing ever more representative ways of Hyper Watchmaking.
