The Astronomia is the epitome of 21st century haute horlogerie 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. Re-engineered from the ground up, the Astronomia Solar is the most compact in our peerless collection of Astronomia calibers.
Despite its close-packed design, the Astronomia Solar Planets displays the precious planets of our Solar System as cabochon-cut precious stone half-spheres, placed on a rotating aventurine base. Its three main arms carry the differential-driven, self-leveling time display, the magnesium globe in hand-painted blue for a spectacular representation of Planet Earth, the one-minute flying tourbillon regulating organ and a Jacob-Cut®, 288-facet, 1.5ct Citrine stone in its center to represent our Sun. The Astronomia Solar Planets makes for a beautifully artistic, highly refined and fully mechanical recreation of our solar system, to be appreciated like it has never been done before.
