Roger Dubuis upgrades its Excalibur Quatuor with hi-tech material
The brand’s innovative Excalibur Quatuor is updated with a new material called cobalt chrome
Its innovative Excalibur Quatuor launched at SIHH 2013 is now updated with a new material called cobalt chrome. The alloy is applied on the watch’s 48mm-diametre case, bezel, case back and crown. MircoMelt technology is used to produce this alloy.
The super-exclusive technology represents just 0.1 per cent of worldwide metallurgy and is often used in aeronautics and astronomy. The benefits of the alloy are aplenty – it’s 100 per cent biocompatible, extremely corrosion-resistant and outstandingly durable.
The 590-part RD101 Quatuor movement is a revolutionary design. Instead of a traditional tourbillon, the movement features four sprung balances and five differentials to compensate for the rate variations caused by the effects of gravity. Only eight pieces will be available.
The house’s iconic skeleton designs are showcased in the new Excalibur Spider Skeleton Automatic. The watch features an openwork dial which makes its highly skeletonised movement largely visible on the dial. Running inside of the watch is the calibre RD820SQ – the brand’s first automatic skeleton movement released in 2015. The watch is available in a limited series of 88 pieces only.
