Roger Dubuis Excalibur Quatuor Cobalt MicroMelt ®

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.
In this bold, fresh interpretation of the Excalibur Quatuor, the gleaming cobalt chrome makes a pleasing contrast with the blue PVD-coated movement barrel cage and bridges, as well as the dial, hour-marker and alligator leather strap. The hand-wound 590-part RD101 Quatuor movement – beats at a frequency of 16 Hz (115,200 vph) with its four sprung balances and five differentials.
Dynamic red and white accents are provided by the printed speedometer-style minute track, the white gold skeleton hands with SuperLumiNova-filled red tips, as well as the red strap stitching.
