No product line is as technical and innovative as the Bugatti Collection and the touch of creative madness that pervades it. In 2004, when Michel Parmigiani visited the car manufacturer for the first time, he noticed the Bugatti Veyron, which he considered to be "an engine that happened to have wheels". He decided to create a timepiece in its image – a wrist-worn mechanical block that happens to tell the time. This founding idea and touch of madness underlay the entire collection. The Bugatti models have since flourished with spectacular mechanics inspired by the automotive world that break watchmaking conventions. The Bugatti 370 places its components, modules and main plates along a horizontal axis, like a car engine. The Bugatti Super Sport adopts the shape of a lug using bevel gears. The PF-Bugatti 390 presents a tubular coaxial assembly, which transmits torque as in automotive mechanics.
