Roger Dubuis Excalibur Spider Huracán Sterrato Monobalancier

No route. No plan. Just the pulse-racing possibility of the unknown journey ahead. This is the mindset of trailblazers, those willing to veer off the beaten track at any given moment. Now, even more fearless adventures are possible as the latest creation from the long-lasting collaboration between Roger Dubuis and Lamborghini Squadra Corse is unveiled with the Excalibur Spider Huracán Sterrato Monobalancier (MB).

A prime example of what happens when incredible watchmakers meet visionary engineers, the heart-pumping timepiece is infused with the horological excellence of the Maison and the spirit of the Huracán Sterrato, an unconventional car.

Roaring into life at Art Basel Miami, the Excalibur Spider Huracán Sterrato MB is set to debut alongside the long-awaited Huracán supercar itself. Maximum traction. Peak acceleration. This is an invitation to steer off road for life’s biggest and boldest thrills.

Powered by raging mechanics


The Excalibur Spider Huracán Sterrato MB timepiece is powered by the RD630 calibre. This horological ‘engine’ is designed specifically to reflect the hexagonal air intakes of Lamborghini Squadra Corse racing cars, just as the symmetry of the twin barrels offers a further nod to the Huracán collection and the multi-fuel tanks of its supercars. Always adopting an unconventional approach, the Maison’s watchmakers have tilted the balance wheel to a 12° angle to achieve peak performance. Found at 12 o'clock to echo the Sterrato rev counter, its flipped positioning provides a better view for the wearer, who can now fully enjoy its spiral oscillations - the beating heart of the watch. Completing these impressive mechanics, the date is featured at 6 o’clock.

When viewed from the back, the semi-skeletonised movement reveals the 360° oscillating mass, reproducing the like-for-like speed effect of a Huracán wheel rim while emulating its design. Supplying 60 hours of power reserve, the automatic monobalancier calibre is a feat of mechanical engineering.

Crafted from hyper-tech materials


The technical mastery of the Maison is further captured by the timepiece’s modern and hyper-tech materials, specifically chosen for their peak lightness and resistance. One such material is SMC Carbon, which is used to craft the 45mm case. A composite material nine times lighter than gold, its use is directly inspired by the design of Lamborghini Huracán’s monocoque chassis and body panels.

Meanwhile, six key minute markers are enlarged to give the bezel an even more expressive shape further evoking the Sterrato’s inimitable fender protectors. Crafted from black DLC titanium, the thickness of these elements is increased to mirror the supercar’s heightened ground clearance, so adrenaline-addicted wearers are always reminded of the thrills that come with a supercar built for action.

Drive in style


Dressed in electrifying orange and audacious red, the timepiece is a stunning demonstration of super-sleek aesthetics. Sharp lines found across the dial from 12 to 7 o’clock and from 12 to 5 o’clock recall the clean-cut lines of the Sterrato’s roof rack. A distinctive feature of every Excalibur Spider Huracán is its crown: inspired by racing nuts, it brings even more roaring style to the wrist.  

When it comes to the strap, a Quick Release System allows the wearer to change it at pit-stop speed, while the fiery camo pattern recalls the gravel abilities of the super sports car. This distinctive motif requires numerous coloured plates to be vulcanized together through a specific process that takes 30% longer than a regular strap, while the inner strap is crafted from black rubber and features the unmistakable pattern of a Pirelli Super Trofeo R tyre. 

Limited to just 28 pieces, the Excalibur Spider Huracán Sterrato MB blends advanced mechanics and hyper-tech materials with adrenaline-charged aesthetics. Always doing what it takes to get ahead and go beyond what’s expected, Roger Dubuis once again proves it is most exciting way to experience Hyper HorologyTM. Because every second of life must be epic.
