Main sponsor of the exhibition 'Galileo's Telescope - The Instrument that Changed the World' at the Nobel Museum in Stockholm, Panerai made the Jupiterium, the company's first astronomical watch.
The Jupiterium is a mechanical instrument that shows the positions on the celestial sphere of the stars, the Sun, the Moon and Jupiter, according to the point of view of the terrestrial observer.
Taking into account the Earth's particular point of view, in Jupiterium the Earth is placed at the centre of the celestial sphere and the other celestial bodies move in relation to it. In particular, the Jupiter system includes the so-called 'Medicean Planets', i.e. the planet's four main satellites, first observed by Galileo Galilei through the telescope, and known today as Io, Europa, Ganymede and Callisto.
The mechanical movement of the Panerai Jupiterium, crafted in titanium, has a 40-day power reserve that also powers a perpetual calendar clock located at the base of the instrument. The perpetual calendar is one of the most sophisticated applications in haute horlogerie and allows the exact determination of the date, day, month and year without the need to intervene on the watch with manual corrections, even in leap years.
Made in only three pieces, the Panerai Jupiterium consists of a square wooden base on which is mounted a glass sphere enclosing the Earth and the planets, supported by titanium arms. The constellations of the zodiac, made of SuperLumiNova, are represented on the surface of the sphere as they are visible from the Earth's hemispheres.
