Parmigiani Fleurier presents a limited edition of its iconic model, the Tonda 1950. Its dial features lapis lazuli, and the brilliance of its crystalline structure is accentuated on this ultra-thin model. The captivating beauty of this exquisite stone with its alternating light and dark blue hues is adorning 50 limited editions. The Tonda 1950 Lapis Lazuli is a celebration of the mineral world and the art of the master craftsman.
Working lapis lazuli on the scale of a wristwatch is a huge technical challenge. The thinness of the cut makes the stone very fragile. Then, 24 minuscule holes must be drilled into it to secure the 12 indices. The slightest scratch or crack in this process will completely ruin the dial. Behind each of these 50 limited editions there are dozens of blanks which attest to the patience of the craftsman and the uniqueness of each dial.
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 PF702 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 tungsten, to ensure inertia, into the calibre, which joined the Parmigiani Fleurier range of movements.
At just 2.6 mm thick, the PF702 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 PF702 movement and its successive variations.
