The Tourbillon 24 Secondes Vision Enamel, which includes the third Fundamental Invention, was born of a very precise wish to showcase a creation of absolute classicism in its purity of line, yet one which simultaneously exudes an incredible timelessness. The sober appearance of the dial and the case with its proportions of maximum refinement enhance a movement of supreme sophistication.
Technically, the Tourbillon 24 Secondes Vision Enamel uses a fast rotation speed and inclined angle to solve the problem of the critical positions of the oscillator in relation to gravity. The 25° angle and the rapid revolution of the tourbillon cage significantly improve the chronometric performance of a system containing only one tourbillon, especially in stable positions.
Hand-finishing by Greubel Forsey: For this timepiece, Greubel Forsey presents, for the first time ever, a grand feu enamel dial. A hand-made model of skillful craftsmanship, and the product of a delicate treatment that enhances its immaculate whiteness, the dial envelopes the whole timepiece in a magnificent aura of luminosity.
In addition, the barrel-polishing of the three-dimensional surfaces of the tourbillon’s arched bridges is taken to the very limit, revealing the famous black polish. The sapphire dome on the back of the timepiece captures luminosity and channels it into the interior, allowing the tourbillon to be viewed through a veritable stream of light.
