Ahead of the Salon International de la Haute Horlogerie (SIHH) 2019 in Geneva next month, Manufacture Roger Dubuis has unveiled its sophomore collaboration with Italian sports car maker Lamborghini. The new Excalibur Huracàn Performante takes its visual cues from the performance variant of Lamborghini’s latest sports car.
It may be recalled that in September 2017, Roger Dubuis announced a five-year-deal with the supercar maker and launched the first watch of the partnership, the Excalibur Aventador S. It was powered by a brand new movement – the 103SQ Caliber which housed a double sprung balance, both placed at 45-degree angle, with a differential and “engine strut bars” placed across the movement – a homage to the Lamborghini V12 engine. A hand-wound skeletonized movement, it was composed of 312 components and included a deadbeat-seconds display.
While the focus of the first watch was on the massively complex movement, with the Excalibur Huracán Performante, the product development team focused less on the technicality of the movement and more on design. The new watch uses a 45 mm skeletonized case - a hallmark of the Excalibur range - made from grade 5 titanium and is fitted with a fluted titanium bezel and a titanium exhibition caseback. The case was shot-blasted using a specific diameter of grain and then galvanic-treated to achieve the “Technical Titan Grey” hue of the Huracán Super Trofeo Evo model. The matt grey and bright yellow color scheme of the watch is inspired by the livery of the Super Trofeo Lamborghini.
The half hexagonal shape of the Huracán Performante’s air intakes is a repeated design motif on the openwork dial. The attention to detail is evident in details like a new crown which is inspired by the racing nuts on the supercar’s wheels, a multi-material ‘spoiler’ used for the open-worked bridges. Even the circular oscillating weight of the self-winding movement is inspired by the Huracán’s wheel rims. Even the grey alcantara strap has a rubber inlay featuring the Pirelli P Zero Trofeo R tread pattern design.
The watch is powered by a new manufacture movement, Caliber RD630, and interactions with the Lamborghini team have had a huge influence on its design. After the complex movement of the Aventador S, the RD630 may seem like a relatively simpler movement but only just. The new movement features a balance wheel that is placed at 12° angle at the 12 o’ clock position. After the V-shaped twin balance of the first watch and the 12° angle seen on the RD630, it is obvious that Roger Dubuis intends to make the tilted balance a signature of the Lamborghini range.
The attention to detail is again visible in the decoration and construction of the movement, especially around the bridges and mainplate. You’ll see hat tips to the supercar’s design again in the construction and finish with details like air-intakes, a grill, and the aforementioned wheel-like rotor. Components have been given a brushed, shot-blasted finish and feature an NAC coating. A “life cell protection unit” is placed around the balance. The movement is composed of 233 components and has a power reserve of 60 hours supplied from twin barrels. The watch is limited to just 88 pieces and is priced at around AED200,000 though the exact price will be revealed during the Geneva salon next month. Owners will be given privileged access to the Super Trofeo racing series.
