This expressive timepiece introduces a bold and captivating colourway, following the thrilling release of the same model in 2022, which showcased a vibrant orange hue. The 2022 version combined cutting-edge mechanics, advanced materials, and adrenaline-fuelled aesthetics, representing the perfect fusion of Roger Dubuis’ renowned Hyper Horology and the fearless engineering of the Sterrato.

Now, for the second time, the gravel is set to churn as this inspired watch design takes a thrilling new direction, offering a sensational new variation.

The RD630 Calibre not only is a work of aesthetic art, with 60 hours of power reserve, this Monobalancier also delivers all the supreme precision and smooth functioning that Roger Dubuis is known for.

The movement embraces the iconic shape of hexagonal air intakes, making a smooth transition between timepiece and car. Also note the twin barrels between 5 and 7 o’clock, a signature feature of the maison’s Huracán watches, and one that pays tribute to the vehicle’s multi-fuel tanks.

Aligned in symmetry to this feature is the tilted balance wheel at 12 o’clock – a flipped position that mirrors the rev counter view on a Sterrato dashboard.

For the date window, Roger Dubuis has taken another unexpected route. When viewed from the back, the date-disc shows an indecipherable series of symbols. From the front, however, the disc rotates in front of a coloured decoder, revealing the digits in their clearest form.

For one final surprise, the impressive caseback delivers a 360° oscillating weight that is directly inspired by the Huracán’s wheel rims. When in motion, it produces the same whirlwind speed effect that you might expect to see on a raw off-road surface.

This blue edition of the Excalibur Spider Huracán Sterrato MB is limited to just 28 pieces, making it a rare collectible for the most serious fans.
