After six years of research and development, in 2004 the Parmigiani Fleurier manufactures presented the unthinkable. The timepiece, christened "Bugatti 370", contains an immense tubular-shaped movement that is worn like an engine block on the wrist, with the time being displayed laterally.

This movement, which can be clearly viewed by the wearer, takes after automotive mechanics more than their watchmaking counterparts as it is assembled on a transverse axis rather than being placed on the flat surface of a single main plate. The movement's various different modules – the regulating organ, gear train, power reserve and double barrel – are built in sections on no fewer than five main plates, which line up in the tubular extension of the block. These modules or "floors" communicate in synergy thanks to a drive shaft that crosses the entire watch from one end to the other, allowing actions to be synchronised, following the exact principle of a car engine.

The wearer of the Bugatti 370 can observe every minute detail of the 337 components comprising the engine block on his wrist thanks to the six sapphire crystals that surround the piece. These crystals mostly have a shape known as "warped", which follows the contours of the movement without corresponding to a pure geometric formula. The production of these atypical sapphire crystals is unusually complex.

The Bugatti 370, which celebrated the creation of the partnership in 2004, truly is a car reborn as a watch. It alone illustrates the potential of a brand whose watchmaking centre is independent and verticalised. Each of its entities communicate and combine their expertise in order to overcome the challenges that arise when we dare to stray from the beaten track and succeed in bringing the most immense of creations to life.
