Set to debut atBaselworld 2016, the Astronomia Clarityoffers a sapphire case variation ofJacob & Co.’s iconic manufacturing movement, the Gravitational Triple Axis Tourbillon.

•  1st Axis - 60 seconds,
•  2nd Axis - 5 minutes,
•  3rd Axis - central axis in 20 minutes

2nd satellite: Hours, minutes dial rotating in 20 minutes on the central axis, equipped with a patented differential gears system;
3rd satellite: 288 faceted “Jacob-cut” spherical diamond rotating in 60 seconds on itself and in 20 minutes;

To enhance the delicately crafted and massively engineered Astronomia tridimensional movement, Jacob & Co. took on an ambitious initiative and developed a sapphire Clarity case.

The sapphire of the Astronomia Clarity is crystalized using the Kyropoulos method to reach the highest level
of purity possible. Extreme care was taken and unique tools were specially developed to shape the sapphire.
Indeed, only a diamond tool is capable of sculpting the Astronomia Clarity sapphire case and barrel bridge. The
finest craftsmen were employed to finish the 16.9° beveled edge and to polish the internal cones, which requires
a minimum of 30 hours to complete.

This special Astronomia collection wears the name: “Clarity,“ as in the state or quality of being clear and transparent to the eye. Completed with a double anti-reflective treatment, the dome shaped crystal top, back and barrel bridge play with the highest level of transparency, offering a 360° panorama of the Gravitational Astronomia movement.
