Chronographs — flyback chronographs in particular — have been close to Roger Dubuis’s heart right from its inception in 1995. Now, there is a new flyback chronograph in the house: Excalibur Spider Revuelto Flyback Chronograph (Ref. RDDBEX1045). It’s an 88-piece limited-edition watch that draws inspiration from the awe-inspiring Lamborghini Revuelto, a ground-breaking creation in the world of high-speed automobiles and the very first super sports V12 plug-in hybrid electric vehicle.
Lamborghini’s new Revuelto is a brutal weapon that produces 814horsepower from a 6.5-litre N/A V12 engine. When combined with three electric motors, the hybrid sports car produces a staggering 1002 horsepower, which gets mated to an eight-speed, dual-clutch transmission. Talking about the interior, there are only two seats in the Revuelto because the Italians put 12 cylinders where the backseats would normally be expected. There are four rotors on the steering wheel that control drive modes. Additional buttons activate the turn signals as well as initiate the launch control. What’s more, Lamborghini has claimed 0-100 km/hour in just 2.5 seconds.
The new Roger Dubuis Excalibur Spider Revuelto Flyback Chronograph bears a strong resemblance to the Excalibur Spider Flyback Chronograph as well as the Excalibur Spider Huracán Sterrato MB, but with some subtle and bold changes. This 45 mm watch has a C-SMC carbon case and a black ceramic bezel with an orange-lacquered 60-minute marking. There is a black DLC titanium crown with an orange-lacquered ring at 3 o’clock; black DLC coating can also be found on the lugs and the chronograph pushers at 2 o’clock and 4 o’clock.
The dial gets a green lower flange with transferred texts and minute tracks and a grey upper flange with screw-like hour markers, rhodium-plated and filled with SLN. The orange-arrowed hour and minute hands are made of white gold with black PVD; there is an orange-varnished central seconds hand as well. The inner periphery has the 500 km/hr tachymeter scale. The timepiece has a column wheel and a date window at 6 o’clock that governs the start, stop, and ‘return to 0’ functions of the chronograph, and also has the added advantage of making the pushers much smoother to operate.
At 3 o’clock, there’s a 120° rotating minute counter (RMC). It includes a patent-pending tripartite hand that carries the 0, 1, and 2, accurately rotating past the 0-9 digits on the right. As soon as the wearer activates the chronograph, the RMC begins to carry out the task it is assigned to execute. At 9 o’clock, the timepiece gets a tilted balance wheel. This balance wheel has raised its level of inertia to the same standard as that of a tourbillon. Additionally, its 12° inclination compensates for the negative effects of gravity. Meanwhile, the diamond-coated silicon escapement wheel is paired with diamond-coated silicon pallet-stones, ensuring sublime anti-magnetic qualities.
The watch’s most Revuelto-inspired element comes into view in the form of a signature “Y” bar in green and white gold on the dial, with perfect lines that mirror the headlights of Lamborghini’s V12 hybrid supercar. The new watch is powered by RD780, offering 72 hours of power reserve. The movement enables instantaneous restarting of the timer function while the chronograph is running. The calibre has an integrated chronograph with two patents: one linked to the second hand of the chronograph and the other to the display of the minute counter.
Turning the watch over showcases the black DLC titanium open caseback with a sapphire crystal. There is a visible vertical clutch, which itself replicates the gear system of the Lamborghini sports car, equipped with a second braking system (SBS). The oscillating weight has been shaped with five arms, like the rims of a supercar’s wheel; it also features the engraving of the individual watch number out of 88. The Roger Dubuis Excalibur Spider Revuelto Flyback Chronograph is finished on a black rubber strap with a green rubber inlay and a black DLC titanium cover with titanium blades and a triple folding buckle; both can be interchanged via the Quick Release system.
