Panerai Presents

Jupiterium

Panerai’s Jupiterium is an intricate mechanical installation that brings centuries-old astronomical discoveries to life.
Inspired by the revolutionary observations of Galileo Galilei in 1610, it serves as both a scientific tribute and a demonstration of horological precision.
In the early 17th century, Galileo used his telescope to observe Jupiter and its four largest moons.
His discovery provided the first empirical evidence that celestial bodies could orbit something other than Earth, challenging the long-held belief in an Earth-centered universe.
Jupiterium replicates these discoveries in a mechanical form, acting as a symbolic extension of Galileo’s eye.

A Tribute to Galileo Galilei and the Patented Planetary Mechanism

​Jupiterium honours Galileo Galilei’s 1610 discovery of Jupiter’s satellites, a milestone that reshaped the understanding of the cosmos. Designed as an artistic and mechanical tribute, it also highlights the zodiac constellations, connecting astronomy and horology. At its core, a patented mechanism brings planetary movements to life, offering a precise representation of celestial motion within a finely crafted horological structure.

Retrograde Motion: The Illusion of Planetary Movement

From Earth, planetary motion appears predictable, but due to Earth’s movement, outer planets sometimes seem to move backward before resuming their course. This illusion, known as retrograde motion, results from the shifting observation perspective. Panerai's Jupiterium accurately captures the astronomical complexity of the Jupiter retrograde on an annual basis showcasing an intricate interplay of celestial motion and mechanical precision.

Zodiac Constellations in Jupiterium

Jupiterium’s design features a wooden frame supporting a glass sphere, which completes a full rotation every 23 hours, 56 minutes, and 4.09 seconds—mirroring a sidereal day. Inside, Earth and the planets are positioned on titanium arms, reflecting the celestial mechanics Galileo first observed. The zodiac constellations, made in Super-LumiNova, illuminate the sphere’s surface, ensuring they are visible from both terrestrial hemispheres.

Mapping the Stars: The Sun, Moon, and Jupiter in Relation to Earth

Jupiterium positions Earth at its center, allowing celestial bodies to revolve around it in real time. Their movements shift based on terrestrial observation points, creating an interactive sky representation. The installation features the four 'Medicean Stars'—the moons of Jupiter that Galileo first documented—reinforcing the historical significance of his discovery. This precise mapping of planetary positions and orbits offers a compelling visualization of astronomical motion.

Perpetual Calendar and 40-Day Power Reserve

Jupiterium’s perpetual calendar movement requires no adjustments until 2099, accurately displaying the day, date, month, and year while automatically accounting for leap years. Engineered to endure, it is designed to continue measuring time, requiring minimal intervention at the turn of each century. Powered by eight barrels in series, its 40-day power reserve relies on 32 meters of springs, which are wound using a specially crafted key requiring 110 turns.
