While the automotive brand presents the Bugatti Chiron, a technical marvel and “super car” of unrivaled power, Parmigiani Fleurier unveils the watch associated with the car: the PF-Bugatti 390 Concept Watch.

The PF-Bugatti 390 is conceived as a motor-bloc on the wrist 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.

This spectacular piece falls in with the proud tradition of the PF-Bugatti family, which transgresses watchmaking conventions and presents exceptional mechanisms.

PF-BUGATTI TYPE 390 CONCEPT WATCH

Modular construction: a tubular engine, which can be removed from its receptacle
Coaxial construction: true precision of assembly

    BASE OF TIME: cylinder – frequency machine = car engine
    DISPLAY: displays the time like an additional module = cockpit

Sections of the tubular movement and dial display:

(4) REGULATION (TB)
(3) TRANSMISSION
(2) ENERGY
(1) SUPPLY – WINDING
(5) DIAL

•     SUPPLY

This section determines:

    Power reserve indication
    Winding of the barrels
    Time setting

Key elements:

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 SYSTEM: Anti-breakage system, which has a free return function.

• ENERGY SUPPLY

    Two barrels ensure constancy in the supply

(Analogy with the two fuel tanks of a Bugatti car)

    Series-coupled barrels with a “triangular coupling” innovation:

    Barrel 1 is directly combined with barrel 2
    Consequently, the energy supply is even more constant

• TRAIN WHEEL

Function: Energy transmission from the barrel to the escapement

    Axial configuration instead of flat
    The classical reduction ratio (alternation of Wheel-Pinion-Wheel-Pinion) is no longer used

The transmission is ensured by a planetary gear, which consists of a central wheel, three satellites and a fixed toothed crown

There are three series of planetary gears that enable together:

    The reduction ratio function
    Transmission of the torque
    The centring of the force at each level

• TOURBILLON

    Flying tourbillon 60 seconds which diameter defines that of the whole concentric tube.
    4 Hz – very rare for a tourbillon ; great inertia of the balance wheel
    Excellent power to weight ratio: very light yet resistant materials. Enables optimal adjustments and compatibility with the COSC standards.

• DIAL

The link with the dial occurs at the level of the central planetary gears (Transmission section)

Recovery of the torque and transposition by means of a worm screw (an exceptional element for a wristwatch), 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
