DESCRIPTION:
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 Arlequino 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 gem-set space inside its spectacular case.
