The Van Cleef & Arpels “Midnight in Paris” recreates a map of the stars in the night sky above Paris. The orbiting of the stars is achieved by using a rotating Aventurine glass disk.
Genuine meteorite stone from 4.5 billion years ago has been set into a disk that surrounds the calendar in the back of the watch.
Van Cleef & Arpels incorporated meteorite because it represents “the only known physical material that provides information shedding light on the creation of the solar system elements”
