Lamborghini Squadra Corse has flicked affiliated watchmaker Blancpain and inked a five-year deal with Roger Dubuis instead. The Excalibur Aventador S timepiece is the new partnership’s first fruit, and draws inspiration from its thoroughbred Italian namesake. Its 45mm case is made from lightweight carbonfibre, with a transparent dial and case back mimicking the Aventador’s open-view V12. The skeletonised self-winding mechanical movement features an X-shaped bridge holding it in place, resembling a top-down view of the Lamborghini’s engine bay.

Dubuis claims it is the first mechanism to use 90-degree double sprung balances linked with a differential. Just 88 units will be made. Dubuis founded his watch company in 1995 having worked for many years creating complications for other brands including Patek Philippe & Co.

It was developed with input from the Toro Rosso Formula 1 team, and can be paired with Casio’s smartphone app via Bluetooth.

The watch can then adjust itself to show the correct local time in up to 300 cities worldwide, and stays charged for up to five months using a solar panel system within the dial.
