The Tonda 1950 Moonbow draws inspiration from two phenomena only apparent to a careful observer and re-imagines a lunar rainbow, or moonbow, on the bezel and a spiral galaxy on the dial. Its flying tourbillon is reminiscent of a spiral galaxy and dances amid celestial beings on an aventurine sky, carefully placed at seven o’clock, a nod to Michel Parmigiani’s birth on December 2, 1950 at 7:08 am. The development of an ultra-thin tourbillon movement is a challenge for any watchmaker. Parmigiani Fleurier found a solution by integrating a platinum micro-rotor into the plate of the movement, resulting in a caliber only 3.4 mm thick. In addition, it is hand-finished with the most admirable decorations in the brand’s manufacture.
