Roger Dubuis - Excalibur Superbia

Roger Dubuis Excalibur Superbia

600 precious stones dress the dial of this piece.

Powered by an obsessive quest for pleasure, freedom, and hedonism, all these characteristics are inherent to its very DNA. 

Mad or possessed?

Roger Dubuis is thus unashamedly guilty of that most serious of the seven deadly sins: Pride, known in Latin as SUPERBIA. Strongly linked to vanity and risk-taking, SUPERBIA is also regarded as having an obsessive addiction to adrenaline, just like, in fact, Roger Dubuis itself. Driven by this, along with its firm belief in living larger than life, Roger Dubuis has created Excalibur Superbia, the ultimate totem for a tribe of people who trust that life is but a game that is for making the most of.

The ultimate example of the Maison’s unshakable pride and excess, Excalibur Superbia is crafted in palladium-enriched white gold and set with exactly 600 precious white diamonds and blue sapphires. This offers a truly extravagant housing for Roger Dubuis iconic signature calibre: a brand-new DOUBLE FLYING TOURBILLON movement, the RD108SQ, inspired by its legendary version launched in 2005, the first double-regulator calibre connected with a differential, built up in volume and adorned with a diamond-set star. For the RD108SQ, paying tribute to Roger Dubuis’ status as a forerunner in the field of this extreme complication mastered by few other watchmakers, in the RD108SQ, the double flying tourbillon is transformed into the ultimate iconic signature.

Sending it firmly into the hallowed halls of World Premieres, the excessiveness of the Excalibur Superbia comes neither from its alloy nor its number of stones. What makes it truly bold is that every stone set on the flange, the bezel, the case and the crown is tetrahedron shaped and assembled with an invisible setting on curved. This is so hard to do on a tetrahedron stone that it took each gemsetter an average of 30 minutes to do a single groove, corresponding to 900 hours for this operation alone on all three sides of the 600 diamonds, plus 420 hours to set the case and bezel – and that’s without even counting the stone-cutting! The entire process takes about three times longer than the same case set with baguette-cut stones. And just for good measure, reaching the very pinnacle of complexity Roger Dubuis-style, in the Excalibur Superbia, this already painstaking, groundbreaking process has been entirely achieved on a curved surface.

Simple, straight and utterly frank , the lines of this exceptional piece of artistry are strongly reminiscent of the spatial art forms favoured by interior design artist KAZ SHIRANE with whom the brand that dares to be different shares a number of characteristics – not least from a visual perspective.

Where no man dares to venture 

Not only has no jeweller or watchmaker ever dared to set a piece in this way, certainly no one has ever been crazy or ambitious enough to do it on a masculine watch. Until now. In this masterpiece in which the complexity of the pattern surpasses any norm known to mankind, master craftsmen at the Maison’s Geneva Manufacture have thus set about creating a backbone structure to encapsulate each stone from the back, complying with the brand’s total determination to avoid any material between the stones themselves.

To complicate matters further, each and every glittering stone in the Excalibur Superbia is a tetrahedron, a shape requiring boundless cutting skill as its extreme thinness greatly increases the risk of breaking.

The concept of impossible is nothing if not meaningless at Roger Dubuis where the next challenge is simply round the corner, so not only did every stone have to be tetrahedron-shaped, the pattern was designed so that all 238 stones featured in the case of the Excalibur Superbia has a different shape and is thus singular. Adding insult to injury, the design also demanded that the long-suffering craftsmen of the Manufacture would at times have to deal with the points of six or seven stones meeting simultaneously in the same spot.
