Spectacular mechanics and high-performance materials

are the venue for this new showcasing of the now legendary Quatuor movement.

The impressive technology of four sprung-balances combined with five

differentials – the power it takes to drive the movement at a frequency of

115,200 vibrations per hour – has found its match in a cutting-edge material,

used for the first time by Roger Dubuis to sculpt the colossal case. 100% biocompatible

and highly corrosion-resistant, cobalt chrome is an alloy obtained through

Micro-Melt technology, a total exclusivity that represents just 0.1% of

metallurgy worldwide, encountered primarily in aeronautics and astronomy. This

astounding tour de force shows off the movement of this Excalibur which, as

ever, has been granted the prestigious Poinçon de Genève.
