Jacob & Co. Bugatti Chiron is a series of watches launched by Jacob & Co. (Czech Leopard) and Bugatti. Inspired by the Bugatti Chiron super sports car, it combines the mechanical charm of the car with the exquisite craftsmanship of the watch, and is highly innovative and artistic. The following is a detailed introduction for you:



Background of cooperation
In 2019, Bugatti Automobile and Jacob & Co. reached a cooperation agreement, and both parties are committed to creating unparalleled timepieces inspired by supercars. Both brands focus on ultimate luxury, mechanical performance and craftsmanship. Bugatti's cutting-edge concepts and designs provide inspiration for Jacob & Co., and Jacob & Co.'s "inspiration comes from the impossible" concept also drives both parties to continue to innovate in the field of watchmaking.

Design features
Exterior design: The design of the case is directly inspired by the Bugatti Chiron sports car. Its shape combines glass and metal materials, and the structural elements echo Bugatti's iconic horseshoe grille, quarter windows, muscular body and eye-catching headlights. Through the unique design, from the case to the movement, people can feel the charm of Bugatti sports cars, and the operation of the internal movement can be clearly seen through the seven sapphire panels.

Movement design: The Caliber JCAM37 movement has a unique architecture inspired by Bugatti's engine. It is equipped with a miniature W-shaped 16-cylinder engine block automatic device, four spiral springs as shock absorbers, and a tubular structure around the 30-degree inclined flying tourbillon, like a protective frame, which highly restores the characteristics of the car engine from appearance to function.

Automatic device: Press the crown on the right side of the watch, the engine will start, the crankshaft will turn, and the 16 pistons will move up and down in the cylinder made of sapphire. At the same time, the two "turbochargers" on both sides of the engine will also rotate with the operation of the engine, bringing a very shocking visual effect.
Power reserve display: It has a power reserve of 60 hours. Its power reserve display is designed in the style of a car oil gauge. The edge of the dial at 9 o'clock also has a universal gas pump symbol, which is very distinctive. Moreover, the movement's travel system and the dynamic system do not use the same set of springs, and need to be wound by turning the crown clockwise and counterclockwise respectively.

Craftsmanship and materials
The case is made of all sapphire crystal, which is a top achievement in advanced watchmaking. Since sapphire is extremely hard, reaching Mohs hardness level 9, it needs to be made with diamond cutting and polishing tools, and it takes several months of computer-aided design, manufacturing and traditional manual polishing to complete. For the manual polishing alone, a craftsman needs to spend about 120 hours, which shows the complexity and exquisiteness of its craftsmanship.
