The most recent wristwatch from Parmigiani Fleurier is an accolade for the Bugatti Chiron, the world’s fastest vehicle with a maximum velocity of 420 km/h (restricted for street use).
Intended to copy the Bugatti Chiron in watch form, the new Parmigiani Fleurier Bugatti Type 390 is a hub of developments and new arrangements with a motor square which is really novel with its horizontal barrel shaped development.
Housed in a chamber, the protected type PF390 features a flying tourbillon flaunting a 80-hour power save thanks to two arrangement mounted barrels. This new sort of “motor” has been thinned down so its width is no bigger than the controller of its 60-second tourbillon, which shows the seconds.
The transmission of information from the rounded construction to the oppositely situated dial is made conceivable thanks to a worm screw which moves twice through a 90° point. This point transmission function empowers a 90º transfer of energy, out of the shut barrel shaped circuit and into the presentation on the dial. The focal planetary stuff train is liable for this transmission to the dial. This arrangement denotes a first in watchmaking.
In addition, this worm screw kills all the issues of indenting (brought about by the hand sliding on the axle) often found in standard watches. Finally, a spring toward one side of the worm screw guarantees consistency and comfort when setting the time on the development by means of the crown.
Roused by the standards behind the development of the Chiron, the originators chose a motor/inside/bodywork plan. Specifically, the horizontal tube shaped development (the “motor”) is associated by a worm screw to the dial and the showcases (the “inside”) which are situated oppositely; the whole gathering is wrapped in a rose gold case and sapphire precious stone (the “bodywork”) through which the moving mechanism can be appreciated. Thanks to its measured development, the development can be eliminated from its housing similarly as a motor would be taken out from a supercar for significant modifications.
Because of the barrel shaped configuration of the development, the standard substituting wheel-pinion-wheel-pinion configuration is supplanted by a transmission utilizing three planetary stuff trains. Each of these three planetary stuff trains is outfitted with a focal train wheel, three planetary pinion wheels and a metallised fixed ring gear. Another kind of component, this planetary stuff train has at no other time been utilized in watchmaking gear prepares and utilizes the littlest metal roller on the planet: simply 1.28 mm in distance across for 12 fired balls estimating 0.2 mm in width. Each of the three planetary stuff trains features three course, making a sum of nine metal balls in all. Another central issue is the fact that the gathering requires no grease: a significant favorable position regarding dependability and support.
The arrangement type coupling ensures a steady transfer of energy and rate consistency for ideal timekeeping. The energy is then transferred by means of the planetary stuff trains to the flying tourbillon controller, toward the finish of the transmission chain which wavers at a frequency of 4 Hz (28,800 vibrations/hour). This Caliber PF390 likewise features a force limiter which ensures the development during twisting by forestalling any inadvertent breakage with a free bring function back.
Additionally motivated by the components utilized for the Bugatti Chiron, the PF390 development is outfitted with a slant gear differential to show the force save. By planning a showcase tube (produced using sapphire) which is peripheral to the development, the Parmigiani Fleurier manufacture built up this novel development in which a force save train wheel drives a fixed toothed ring gear inside the cylinder. This shape turns on two guide rings thereby empowering the force save to be perused on the cylinder, by methods for a fixed hand.
The Caliber PF390 flaunts extraordinary finishes across the entirety of its components. Encased in a titanium confine intended to control the forces at play without any deformation, the two barrels are engraved – one with the mark of Louis Chiron, the other with the engraving “le vieux renard” (the old fox), in reference to the epithet of this incredible dashing driver.
The dark openworked dial features brilliant applique records and hands which make a glaring difference to guarantee ideal decipherability. Thanks to the 60-second tourbillon, the seconds can be perused the magnifying effect of the sapphire precious stone toward the finish of the chamber.
Roused by the fluid bends of the Bugatti Chiron, the 42.2 x 57.7 x 18.4 mm (height) case is crafted from white gold or pink gold and engraved on the back with the engraving “Release LIMITEE 10 PIECES” (10-piece restricted version).
This case was made by Les Artisans Boîtiers – one of Parmigiani Fleurier’s manufacture divisions; built around the round and hollow design and water impervious to 3 ATM, it stands apart thanks to its capacity to rotate 12° around its drive shaft (patent forthcoming), to guarantee perfect ergonomics around any wrist.
The gator leather tie is endorsed by Hermès and is fitted with a gold folding clasp. The cost of the Parmigiani Fleurier Bugatti Type 390 (10 pieces in white gold with ref. PFH390-1201401-HA1442 and 10 pieces in pink gold with ref. PFH390-1001401-HA1442) is Swiss Francs 295,000. parmigiani.com
