[dropcap size=small]W[/dropcap]hen two high-octane brands such as Roger Dubuis and Lamborghini Squadra Corse (Lambo’s motorsport division) combine their creative forces for good, you get a technical masterpiece like the Excalibur Aventador S.

Cast from light carbon-fibre and inspired by the engine block of the Aventador, the 45mm timepieces parade a slew of technical innovations that warrant their own patent protections. Two of these concern the implementation of dual balance wheels (convention: one) and consequently obtaining more accurate time. The remaining three patent filings stem from applying principles of supercar construction to help the watches shed weight and make tremendous gains in efficiency; an entire gear-train, for example, was dropped from the already light construction of the Excalibur Aventador S.

As a nod to the exclusivity of the timepieces, the watches come with an exceedingly rare complication that only true watch cognoscenti will identify and tip their hats to: the deadbeat seconds display, which intentionally regulates the ticking of the second hand in a mechanical watch to once per second, a la a quartz piece.

A limited 8-piece run of the Excalibur Aventador S in a sizzling new color variant, Green, was just unveiled at the recently-concluded Geneva Motor Show. The bi-material strap with green trim pairs nicely with the green rubber overmolds that line the crown and case, as well as with the markings on the bezel.
