The Astronomia is the epitome of 21st century ultra-high-end watchmaking and a globally recognized symbol of Jacob & Co watchmaking expertise. A world-first both in the boldness of its unprecedented concept and its entirely mechanical construction, the Astronomia has gone beyond impressive horological achievements and has been regarded as an outstanding multidisciplinary engineering achievement.

The Astronomia Tourbillon Baguette connects Astronomia with Jacob & Co’s singular gem-setting know-how. It is a cinematic sculpture animated by its four-arm movement construction that rotates and floats through the sapphire and diamond-bound space inside its spectacular case. A grand total of 342 invisibly set, baguette-cut diamonds adorn the dial’s backdrop, while 80 invisibly set, baguette-cut diamonds make up the lugs.
