Jacob & Co Bugatti Chiron Tourbillon

This breathtaking Jacob & Co. Bugatti Chiron Tourbillon is a unique piece, crafted from green sapphire crystal — a technical and artistic feat requiring hundreds of hours of machining and polishing. The transparent case allows a full 360° view of the intricate engine-inspired movement, while the vivid emerald hue makes it one of the most visually striking versions ever produced.

Inside, the manually wound JCAM37 caliber replicates the heart of the legendary Bugatti Chiron: a fully functional miniature W16 engine. With a press of the right-hand crown, sixteen tiny pistons move up and down inside the transparent engine block, powered by a complex crankshaft system — a spectacle of mechanical art.
