The sky layer dial is dark blue titanium with white stars and the tourbillon, the time dial, and nine planets all revolve 360 degrees every ten minutes in a fascinating animatronic that was invented 224 years ago, but refined here to a "Disney" quality animation. The large circular dark blue time dial has 12 gold hand-engraved and filled Zodiac images and sectors to define the hours, and broad gold Dauphine-style blunt hour and minute hands. There is an 18k rose gold open worked flying tourbillon structure with a Jacob & Co logo that rotates in 60 seconds. A 1.5ct. Jacob-cut citrine stone Sun is in the center with a hand-painted magnesium rose gold and blue lacquer earth and 7 more cabochon-cut or faceted precious stone planets including a Rhodonite Venus, a White Granite Mercury, a Pietersite for Jupiter, Red Jasper for Mars, Lapis Lazuli for Neptune, Blue Calcite for Uranus, and there is an 18K rose gold-ringed Tiger Eye Saturn. It has a 48-hour power reserve at full winding, it's water resistant to 30 meters/100 feet, and the 22mm thick case, dial, and movement are all signed. This Jacob & Co Astronomia Solar AS300.40.AP.AK.A has a manual winding Jacob & Co JCAM19 double axis tourbillon movement with twin rotating platforms with three main arms that move the differential-driven, self-leveling time display which rotates 360 degrees counter-clockwise along with the Aventurine base and other celestial bodies every ten minutes. It's constructed with 43 jewels, circular graining, sandblasted plates and bridges, a polished sink and screws, an anti-shock device, a self-compensating flat balance spring, and the mechanism oscillates at a frequency of 28,800 vph (4Hz).
