DESCRIPTION:
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.
The Astronomia Solar Zodiac recreates our Solar System, placed on the rotating platform of the Astronomia Solar caliber. Its three main arms carry the differential-driven time display, the magnesium globe in hand-painted blue lacquer for a spectacular representation of Planet Earth, and the one-minute flying tourbillon regulating organ, all rotating clockwise in ten minutes. Underneath, the aventurine base dial holds semi-precious stone plans, while turning counter-clockwise in 10 minutes.
- Precious and Semi-precious stones representing the sun and the planets
- The Jacob & Co. flying tourbillon, Zodiac Sign time display, hand-painted magnesium globe and flying tourbillon make one full revolution of the dial in 10 minutes, rotating clockwise
- The aventurine dial holding the eight planets makes one revolution counter-clockwise, in 10 minutes
- The seven planets are represented by half spheres of semi-precious stones: White Granite for Mercury, Rhodonite for Venus, Red Jasper for Mars, Pietersite for Jupiter, Tiger Eye for Saturn, Blue Calcite for Saturn and Lapis Lazuli for Neptune
- With the upper assembly turning clockwise in 10 minutes and the aventurine base holding the planets turning clockwise in 10 minutes, the Astronomia Solar never looks the same way twice
