The special connection between the Tonda 1950 and diamonds shone through the moment the stone-set bezel made its appearance in the women's collection. It was time for Parmigiani Fleurier to present a fully set model that pairs the timeless elegance of the Tonda 1950 with an enchanting dial, completely studded with diamonds.
The Tonda 1950 is the aesthetic essence of Parmigiani Fleurier as it showcases all the brand's signature codes – and nothing else. The thin, slender profile with the two emblematic lugs; the cut round crown; the delta-shaped hands. Simplicity is key, but each of its proportions has been carefully calculated to create a coherent elegance and harmony that draws in the gaze.
Three years of research and development were needed to successfully create the PF701 calibre, an ultra-thin automatic movement. The main challenge was to incorporate the rotor into the calibre itself without adding to its thickness. The solution was to integrate a micro-rotor made from platinum, to ensure inertia, into the calibre, which joined the Parmigiani Fleurier range of movements.
Five different cuts of Top Wesselton diamonds adorn the dial in an intricately arranged configuration. They give rise to a perfectly soft transition between the stones, with the smallest set in the centre, gradually increasing then decreasing in size towards the edge. Each diamond contributes to this spectacular whole, creating a seemingly domed, trompe-l’œil effect thanks to the play of light sparkling within the gemstones.
At just 2.6 mm thick, the PF701 movement owes its slim profile to an off-centred micro-rotor directly integrated into the main plate. This component winds the movement, which has an autonomy of 42 hours. This calibre was developed to allow for the addition of multiple functions — such as a calendar or moon phase indication — without altering the slender proportions of the Tonda 1950 family. This serves as proof of the excellent design of the PF701 movement and its successive variations.
