It started with an idea conceived by Jacob & Co. together with Bugatti - how to reproduce the visceral sensation of the iconic Bugatti 16-cylinder engine in a timepiece.

After almost a year of development working together, they created the Bugatti Chiron Tourbillon. Everything in this timepiece is designed to honor the Chiron hyper sports car. The sleek tonneau-shaped case is inspired by the flowing lines of the Chiron. The movement powers the timing functions, a 60-second flying tourbillon and, most importantly, a fully operational recreation of the Bugatti iconic W16 engine. The entire movement is on display beneath a wide piece of sapphire crystal.

The Bugatti Chiron Baguette Yellow Sapphires is a unique piece in 18K rose gold. It features 341 specifically cut yellow sapphires, weighing approximately 18.21ct on the case, 60 on the three crowns and pushers (2.25ct), 18 more on the buckle of the rubber strap (2.26 ct), and one last yellow sapphire sitting on top of the flying tourbillon with a 30° incline. The total number of yellow gems on the Bugatti Chiron Baguette Yellow Sapphires is 420, for a total weight of approximately 22.82 ct.

In 2019, Bugatti and Jacob & Co. signed a multi-year partnership to create unique, never-before-seen timepieces. These watches are true to the spirit of both companies, while taking watchmaking to impossible heights.

To inaugurate this partnership led by performance, two timepieces were created. These watches, based on the Twin Turbo Furious and the Epic X Chrono, were directly inspired by the unique design and spirit of Bugatti hypercars.

In 2020, Jacob & Co. and Bugatti introduced new watches in the Twin Turbo Furious collection, and the Bugatti Chiron, a completely new line.

Pushing the right crown of the timepiece activates a groundbreaking watch complication: a fully working replica of a Bugatti W16 engine. The crankshaft turns and the 16 pistons pump up and down, just like a true internal combustion engine. Two "turbochargers" (down from four in the actual Chiron engine) on the side of the engine block spin while the engine runs, adding to the visual impact.

Incredible to see and extremely difficult to realize (the movement is comprised of 578 components), the Bugatti Chiron Tourbillon timepiece has done something no one has ever even attempted before - to seamlessly marry engines and watches.

The Bugatti Chiron Tourbillon features a 30º inclined tourbillon, the first time Jacob & Co. has ever used an inclined tourbillon. The "flying" part of the tourbillon means that the regulating organ is only supported from underneath, so the tourbillon is even more mesmerizing. The 30º inclination makes it easier to admire this incredible complication through the replica of the Bugatti horseshoe-shaped grille.

The Bugatti Chiron Baguette Yellow Sapphires adds a single, 0.1ct yellow sapphire on the tourbillon.

The movement is completely suspended in four places, with what looks like actual automobile shocks from the Chiron. The movement is, in fact, floating inside the case. You can see it move up and down. Framing the engine block are two "exhausts," completing the engine theme of the design.

The power reserves for the animation and the power reserve for timekeeping are different, yet both are wound through the winding crown, clockwise for the movement, counterclockwise for the engine animation. The power reserve indication for timekeeping even has the universal gas pump symbol on the side of the gauge at nine o'clock.

The crowns for the Bugatti Chiron Baguette Yellow Sapphires are at the bottom of the case - the left crown sets the time, the middle crown winds both the movement (60 hours of power reserve) and the animation, and a push of the right-hand crown starts the animation. The crowns and pusher are paved with 60 baguette yellow sapphires (2.25 ct).

The suspension of the movement caused an additional challenge for the designers, as they had to create (and patent) a special automotive-style jointed transverse system so the crown stems aren't damaged by the movement going up and down inside the case.

The Bugatti Chiron Tourbillon from Jacob & Co. is a world-first - a true engine on the wrist.
