The Antikythera Sunmoon by Hublot is a watch with a design based on the Antikythera mechanism discovered in Greek waters in 1901. The mechanism is considered to be the first astronomical calculator and dates back to around 150 BCE. The watch it inspired has astrological symbols on the chapter ring and constellations on the hour hand. It displays sun and moon indications both of which can be found on the dial side. It also includes both a solar and lunar calendar.
It runs with a 21,600 VPH (3 Hz) frequency and a 120-hour power reserve. The movement contains 295 components and seven complications. The watch is a limited edition as Hublot will only be creating 20 pieces.
