The Midnight Planétarium watch accurately displays the movement of 6 planets in our solar system as they orbit the Sun. Each planet is represented by a precious or semiprecious stone (serpentine for Mercury, chloromelanite for Venus, turquoise for Earth, red jasper for Mars, blue agate for Jupiter and sugilite for Saturn). Unfortunately, the remaining two planets were excluded because of their orbits. In total, the watch took three years to complete and costs $245,000.
