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 Jacob & Co. flying tourbillon, Zodiac Sign time display, hand-painted magnesium globe and three 288-facet Jacob-cut gemstones make one full revolution of the dial in 10 minutes, rotating clockwise
- The Sun is represented by a yellow 288-facet Jacob-cut Sapphire (≈ 1.5 cts)
- The dial holding the eight planets makes one revolution counter-clockwise, in 10 minutes
- This base dial is invisibly-set with baguette white diamonds
- The lugs of the 18K white gold and sapphire-case are invisibly hand-set with baguette-cut white diamonds.
- The eight 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 diamond-set base holding the planets turning clockwise in 10 minutes, the Astronomia Solar never looks the same way twice
