Robert Greubel and Stephen Forsey's primary intention was to present their third invention, the Tourbillon 24 Secondes, in a case that is as slender as possible and yet able to accommodate the unique inclined Tourbillon cage.
It was the lateral projections of Greubel Forsey's asymmetric models that inspired this original solution. By incorporating a dome into the sapphire crystal on the back of the timepiece, they have created enough extra volume to allow the Tourbillon cage to overlap the reference surface of the movement bridges
The dome is a new and intriguing element that draws attention to the lower Tourbillon bridge. The bridge itself is more than just a simple support; it is a triumph of technology and craftsmanship. Its geometry is like a Romanesque vault and its arched and barreled surface is delicately polished by hand. Obtaining a perfectly regular reflection over the whole piece requires such expertise and experience that each bridge finished in this way is discretely signed by the artisan-decorator who executed it
Completing the exceptional standard of decoration that naturally applies to all 288 parts in the movement, the unique composition of colors and finishes creates a spectacular visual dynamic, with pride of place given to the sectorial 72-hour chronometric power-reserve indicator.
This new creation is also distinguished by its elegant, neoclassical simplicity. The overall aesthetic is highly refined, and pays tribute to the craftsmanship and finesse of each component. The fast-rotating Tourbillon 24 Secondes is also an integral part of the graphic composition of the entire piece. Set inside a light-well, it creates an animated scene that is an irresistible invitation to explore the movement-side of the timepiece.
