The flagship Quadruple Tourbillon that showcases Greubel Forsey’s second fundamental invention is now presented with a new three-dimensional black-polished dial.
For this timepiece Greubel Forsey pushes the limits of applied art by presenting, for the first time ever, a black-polished dial. This hand-made finish of polished perfection has on this occasion been applied to an unusually large surface, covering the entire surface of the dial. An awe-inspiring achievement. When reflecting direct light, we see a blue of a depth seemingly never before attained. This technical challenge involved calling into question conventional methods to find solutions that could give rise to such an extraordinary result. An approach requiring great talent, infinite patience and prodigious dexterity.
Technically, the four tourbillons offer a spectacle of astonishing elegance as they perform an ethereal, perfectly choreographed ballet. Each connected to a spherical differential, they contribute independently to obtaining a precise and reliable timing rate, especially in stable positions. The spherical differential transmits the average timing rate of the four tourbillons, thus improving the chronometric performance of all the regulating organs. In view of the impressive number of individual elements making up the movement, the case has been sculpted with asymmetrical forms. An asymmetry that forms an aesthetic reflection of the asynchronous dynamic of the four tourbillons.
