For its latest timepiece from Excalibur Collection, Roger Dubuis incorporates an innovative material: cobalt chrome.
This high-performance cobalt chrome alloy clothing the 48 mm-diameter case, bezel, case-back and crown is produced using the extremely exclusive MicroMelt® technology that represents just 0.1% of worldwide metallurgy. Widely associated with aeronautics and astronomy, this process involves melting and atomizing the alloy into a fine powder by introducing the molten metal to a high-pressure stream of gas using a dedicated vacuum induction melting gas atomization unit.
