Roger Dubuis Excalibur Quatuor Cobalt MicroMelt

With SIHH around the corner, Roger Dubuis shows what 2017 will be made of with the extravagance, high performance and technical savvy of the Excalibur Quatuor Cobalt MicroMelt.

When it comes to progressive complications, the hand-wound 590-part RD101 Quatuor movement – beating at a frequency of 16 Hz (115,200 vph) with its four sprung balances and five differentials – is as progressive as they get… Not to mention outstandingly fast and efficient, since it achieves instantaneously what the tourbillon takes a full minute to accomplish – namely compensating for the rate variations caused by the effects of gravity on a watch. 2017 will see it welcome its very own disruptive 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.

As well as the improved chemical homogeneity of this material, Roger Dubuis naturally appreciates the fact that it enables the creation of specific alloys (such as metal and non-metal) that other techniques do not permit, as well as resulting in controlled porosity that in turn ensures stabilized alloy quality.

 

However, as always in making such technical and aesthetic choices, the Manufacture adopts this state-of-the-art material with watch wearers firmly in mind, since it is

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.

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.

We expect to receive this new Roger Dubuis Excalibur Quatuor Cobalt MicroMelt in April 2017.
