To save on space, Parmigiani Fleurier created a "flying" tourbillon whose cage is mounted only on a lower support bridge. A highly sophisticated ball bearing replaces the mounting function, without adding to the thickness of the movement. Flush with the surface and therefore visible in the foreground, the cage appears to float weightlessly in front of the ultra-thin movement. The tourbillon dances before the eyes to produce a captivating, almost hypnotic visual effect.

The tourbillon cage is usually made from steel, a strong metal which is easy to work. In using titanium, Parmigiani Fleurier is aware to have chosen a flammable material which is very complex to machine at such small dimensions. However, titanium enables the brand to produce the world's lightest tourbillon cage. Its very low weight and inertia enable rotational movement with no loss of torque.

The Tonda 1950 Tourbillon is the aesthetic essence of Parmigiani Fleurier as it clearly showcases all the brand's signature codes. The thin, slender profile with the two emblematic lugs; the cut round crown; the delta-shaped hands, the tourbillon at 7:08, which is the time of Michel Parmigiani's birth.
