Jacob & Co. together with Bugatti spent almost a year developing a unique timepiece that reproduces the visceral sensation of the iconic Bugatti
16-cylinder engine.

What they ended up creating is the groundbreaking 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 and a 60-second flying tourbillon.

Most importantly inside the case is a fully operational recreation of the iconic Bugatti W16 engine, powered by the same movement. When the automation is activated, the "engine" comes to life with its 16 pistons pumping and two turbochargers spinning.

The Bugatti Chiron Blue Sapphire Crystal goes one step further by creating a watch case made completely out of sapphire crystal. It is one of the top achievements in high watchmaking. It was the result of several months of materials processing, high level machinery and hand polishing to produce a case that exposes every part of the 578 hand-decorated and hand-assembled components of the JCAM37 manual wound caliber, making this timepiece every bit as admirable as the car that serves as its inspiration.

Adding color to the sapphire crystal complicates the process of creating the Bugatti Chiron case further. However, the final results show that the effort is worth it as the case exhibits a unique Blue color while maintaining its transparency.
