Parmigiani has thinnest flying tourbillon calibre


Parmigiani Fleurier has released a new watch with the world’s thinnest automatic flying tourbillon movement.

The Parmigiani Fleurier Tonda 1950 Tourbillon features the PF517 movement, which uses a platinum micro rotor to limit its depth to just 3.4mm. The movement took two years to develop and sees the micro rotor, barrel, tourbillon cage, time-setting mechanism and central display system mounted into the same plate.

The Tonda 1950 Tourbillon is the first Haute Horlogerie model in the Tonda 1950 family and is introduced with five dial versions: grey mother of pearl, white or black jade, grained white and blue abyss with Côtes de Genève decoration.


The titanium flying tourbillon cage is also the world’s lightest at just 0.255g and is rear-mounted using ball bearings. Running seconds are indicated by a blued hand integrated into the 60-second tourbillon cage.
