In 2009, the Tondagraphe was added to the Parmigiani Fleurier Haute Horlogerie collection.
It is driven by the in-house PF354 movement, which comprises 295 components and has a power reserve of 72 hours. This Grand Complication movement combines the hypnotic beauty of the tourbillon with the technical function of the chronograph. It was produced in several stages in the Manufacture's workshops, in a process involving professionals from a range of disciplines. Standing out perfectly on the dial at 6 o'clock, the cage that encloses the regulating organ turns on its axis at a rate of one rotation a minute.
The Tondagraphe is housed in an elegant 43 mm diameter white gold case typical of the Fleurier-based brand. A redesign has made the case broader and more open. It now integrates a bezel that gives the piece an even bolder character and a more generous layout of the time indications on the dial.
The face of the Tondagraphe features "Côtes de Genève" decoration in the centre, imbuing it with a rhythmic elegance. Offset at 3 o'clock-6 o'clock, two rings mark the contours of the tourbillon cage and the chronograph's 30-minute counter. The tachometer is used to measure speeds of up to 3km/h, and is one of the chronograph indications.
