THE COMPLICATIONS AND FEATURES

THE ROTATING PLATFORM
The most visually striking feature of Astronomia Tourbillon is its structure. From the aventurine glass back-dial emerges a vertical platform. It revolves on its own axis in 20 minutes. Its constant motion powers all the movement's functions and indications.

THE TRIPLE-AXIS FLYING TOURBILLON
At the end of one satellite arm hangs a double-axis tourbillon. It's held inside an openworked carriage. It revolves on two axes, one in 60 seconds, the other in 5 minutes. Since it travels along with the central platform, this adds a third axis, with a 20 minute rotation period. With a single attachment point, this is a flying tourbillon.

THE ORBITAL DIAL
At the end of another satellite arm lies the hour and minute dial. The platform rotation would normally shift the numbers and make their reading impossible. Jacob & Co. has fitted the dial with a patented differential system. It spins in the opposite direction of the platform, at the same speed. As a result, it remains constantly upright and readable.

THE EARTH
As Astronomia Tourbillon represents a solar system, it contains our home planet. Crafted out of magnesium for lightness, earth is hand-lacquered in blue for likeness. The shape of emerged grounds and continents is clearly visible. This Earth spins on its own axis every 60 seconds.

THE DIAMOND MOON
Astronomia Tourbillon features a moon. That's the planet chosen to represent the high jewelry part of Jacob & Co.'s identity. This moon is actually a 1 ct. white diamond. Carved from a large rough of extremely high quality, it receives the exclusive, spherical, 288-facet, Jacob-cut. This moon spins on its own axis in 60 seconds.
