EXCALIBUR QUATUOR COBALT MICROMELT®
Again, this is the Roger Dubuis Quatour that mesmerised us before, but the innovation for this reference comes with a case made from a “disruptive” material: cobalt chrome. This alloy is a result of an incredibly complex process called Micromelt that involves melting and atomising the material into a fine powder before being processed into hot-rolled bars. Often associated with aeronautics and astronomy, the material of the 48MM case of the Quatour 100-percent biocompatible and extremely corrosion-resistant. This gleaming case makes a brilliant accompaniment to the hand-wound 590-part RD101 Quatuor movement that has been PVD coated with blue.
