POWERFUL DESIGN

Excalibur, the iconic and prodigal Roger Dubuis collection – with its signature blend of technical excellence and powerful design will take centre stage at the SIHH 2017. The daring luxury Swiss maison will introduce three code-breaking, convention-blasting Excalibur models exemplifying the revolutionary approach that is all about deconstruction – splitting, fissures, ruptures and diversion – as a prelude to generating new aesthetic and technical life.

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. 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.

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. This powder is then blended and screened to a controlled diameter, poured into canisters that are sealed and subjected to hot isotactic pressing to achieve full denseness, before being hot-worked to produce hot-rolled bars and then processed to finished size.

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.

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 100% biocompatible, extremely corrosion-resistant thanks to the spontaneous formation of a passive protective film, as well as outstandingly durable thanks to its multiphase structure and the precipitation of carbides.

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.

Synonymous with the contemporary outdoor, automobile-inspired vibe embodied in the Roger Dubuis Technical Skeletons, the Excalibur Spider Skeleton Automatic is a fresh blue/black/red expression of the talent and ingenuity deployed by the pioneer of contemporary skeletons, showcasing its ability to raise this workmanship to the rank of a contemporary art form.

Leveraging the expertise acquired over the years through its avant-garde movements revealing its own unique vision of this principle, the generous 45 mm titanium case is interpreted according to the Spider concept that extends skeletonization beyond the movement to include the case, flange and hands.

In this new Excalibur Spider Skeleton Automatic version, cool colour contrasts are the keynote, achieved by DLC treatment of the case, and crown, vulcanised rubber details on the bezel, crown and container, along with red accents provided by the ring, crown, hand tips and strap stitching.

The multi-material strap with its black rubber base and blue calf leather inlay is secured by a DLC-treated titanium folding buckle. This ruggedly handsome model is driven by Caliber RD820SQ – which in 2015 became the first Roger Dubuis automatic skeleton movement.

All faces of its 167 components are meticulously hand-crafted in accordance with the stringent quality criteria and prestigious finishing governing the Poincon de Geneve certification.

The design and height of the famous Roger Dubuis micro-rotor – a first in a skeletonized automatic Roger Dubuis movement – effectively enhance the spectacular 3D effect favoured by the Manufacture, as does the raised position of the signature Astral Skeleton decor.

Issued in an 88-piece limited edition, the Excalibur Spider Skeleton Automatic is a vibrant microcosm of the traditions, innovation and expertise cultivated and perpetually enriched by the specialist of technical and architectural mechanics.

Like the electric blue lava bursting from certain volcanoes, the Excalibur Essential 36 Automatic appears with an arrestingly beautiful black DLC-treated titanium case topped by a bezel set with 48 blue sapphires. Simultaneously evoking fire and ice, the sparkling gems reflect and accentuate the cool gleam of the blue PVD-coated dial with its shimmering sun-brushed finish.

This elegant smaller-sized interpretation of the Excalibur carries the collection’s trademark fluted bezel and triple lugs, together with the radiating Roman numerals. The latter are deliciously interrupted by an ever-useful small seconds sub-dial at 6 o’clock, complete with a discreet yet legible date display. The versatile 36 mm diameter makes it suitable for both masculine and feminine wrists, and there is sure to be a gender mix among the lucky few who will own one of this 28-piece limited edition.

It is equipped with the RD830 calibre featuring a 22K pink gold rotor that may be admired in action through the transparent sapphire crystal case-back and ensures a 48-hour power reserve. Setting a perfectly elegant finishing touch, the matching blue alligator leather strap is fitted with DLC-treated titanium folding buckle.
