Parmigiani Fleurier - Tonda 1950 Tourbillon

| No comment
After two years of research and development, Parmigiani Fleurier presented the world’s thinnest automatic flying tourbillon with micro-rotor, a feat that equips the new Tonda 1950 Tourbillon, a timepiece that combines the simple and elegant lines the Tonda collection with a Haute Horlogerie complication.




To achieve the exceptional thinness of the 3 Hz (21,600 vph) PF517 movement at just 3.4 mm, the micro-rotor in 950 platinum is directly integrated in the main plate, without adding to the thickness with an extra layer.


Integrating the micro-rotor, the barrel, the tourbillon cage, the time-setting mechanism and the central display system in the same main plate was a big challenge that Parmigiani Fleurier approached without offsetting the time display.

To economise on space, Parmigiani Fleurier created a flying tourbillon whose special feature is a cage mounted on a single support bridge. A ball bearing replaces the mounting function, without adding to the thickness of the movement.

Thanks to the decision to use titanium, Parmigiani Fleurier was able to create the world’s lightest (0.255 g) tourbillon cage. Its very low weight and inertia enable rotational movement with no loss of torque. The tourbillon’s efficiency is increased and the chronometry of the timepiece improved.


Made from blued steel, the seconds hand forms an integral part of the tourbillon cage. In fact, this hand is not produced separately to the tourbillon but from the same manufacturing department with the important task to precisely counterbalance the weight of the other components that make up the tourbillon cage.


The tourbillon’s orientation, determined by an angle corresponding to 07:08, is highlighted by a red applique around the edge of the seconds.

The bridges of the movement are decorated with an oblique pattern formed of a series of Côtes de Genève. Their design, which follows a circular arc, take the form of a wave, reflecting the oscillations of the tourbillon which spread through the movement.


The Tonda 1950 Tourbillon is available with five dial versions: white or black jade with a white gold case, grained white or blue abyss with Côtes de Genève decoration and a red gold case, and grey mother of pearl with a white gold case featuring a precious diamond-set bezel.





For all models, the case has a diameter of 40.20 mm and a total thickness of 8.65 mm. The price of the Tonda 1950 Tourbillon is US$ 130,000 except for the version with grey mother of pearl dial and diamonds which has a price of US$ 135,000. parmigiani.ch
