Parmigiani Fleurier – Bugatti 390

During the Geneva International Motor Show 2016, Parmigiani Fleurier is unveiling a new milestone in partnership with Bugatti. While the automotive brand presents the Bugatti Chiron, Parmigiani Fleurier unveils the watch associated with the car: the PF-Bugatti 390 Concept Watch.

She is the representative of a new generation of Bugatti timekeepers. The PF-Bugatti 390 is conceived as a motor-bloc which movement takes a tubular, perfectly concentric shape. This coaxial structure splits the functional sections of a movement into separate compartments, which are in mutual interaction just like the motor of a car.

The concept and the structure of the PF-Bugatti 390 are divided in 5 different parts:

  • SUPPLY WINDING
  • ENERGY
  • TRANSMISSION
  • REGULATION
  • DIAL

SUPPLY WINDING

Supply is the section that manage the power reserve indication, winding of the barrels and the setting time. The key elements of the section are:

  • Clamp Rod: A unique piece that replaces four components (trigger piece, humper, lever, lever spring) and ensures the transition between the winding of the barrels and the time setting.
  • Torque Limiting Syste: Anti-breakage system, which has a free return function.

ENERGY

The energy is powered by two series barrels with triangular coupling that ensure a constancy in the supply (Analogy with the two fuel tanks of a Bugatti car).

TRANSMISSION

The transmission is ensured by a planetary gear: a central wheel, three satellites and a fixed toothed crown. Three series of planetary gears that ensure the reduction ratio function, transmission of the torque and the centring of the force at each level.

REGULATION

The regulation takes place through a Flying tourbillon 60 seconds with an excellent power to weight ratio. The light and the resistant materials consent a optimal adjustments and the compatibility with the COSC standards.

DIAL

The change of the level from the tubular structure to the dial happens at the transmission level. Recovery of the torque and transposition by means of a worm screw which enables:

  • Angle function : the energy switches to a new plane and exits the closed tubular circuit, thus allowing a dial-display
  • Anti-return system: irreversible mechanism, maintaining the hands’ original position
  • Robust and reliable mechanism
