Time and space converge in the latest masterpiece of haute horlogerie: the Grand Planetarium Eccentric Meteorite. This extraordinary timepiece is crafted from a genuine meteorite fragment—once part of an asteroid’s core, drifting through space for billions of years before falling to Earth 50,000 years ago. Now, this celestial relic has been transformed into an exceptional watch, uniting cosmic heritage with unparalleled horological innovation.

At the heart of this timepiece lies a groundbreaking complication: the Eccentric Planetarium, the only mechanical Grand Planetary Complication in the world that accurately displays all eight planets—Mercury, Venus, Earth and her Moon, Mars, Jupiter, Saturn, Uranus, and Neptune—moving in real time around the Sun. This breathtaking mechanism captures the celestial dance of our Solar System with unmatched precision, making it a true marvel of both astronomy and watchmaking.

A Celestial Fusion of Science and Art
Master watchmaker Pim Koeslag has meticulously sculpted this timepiece, ensuring that its construction reflects the grandeur of its cosmic origins. The meteorite case, weighing 47 grams, is carefully crafted out of a 1.09 kg space stone. This extraordinary material shaped by the universe itself, features a unique Widmanstätten pattern, formed over millions of years of slow cooling in space, making each case truly one of a kind.

The dial is a celestial spectacle in itself: crafted from aventurine glass (goldfluss), it mimics the night sky, complete with zodiac constellations. The Eccentric Planetarium features hand-painted planetary orbits, while the meteorite dial ring, set between Mars and Jupiter, signifies the asteroid belt and contains real fragments of a martian nakhlite meteorite —a piece of another world encased within this exceptional timepiece.

A Timepiece Beyond Time
Encased in domed sapphire crystal, the 44mm meteorite case showcases the celestial ballet within. The sapphire crystal case-back reveals the movement’s intricate craftsmanship, while the dark blue hand-stitched leather strap and platinum folding clasp complete this cosmic masterpiece.

“The Grand Planetarium Eccentric Meteorite is more than a watch. It is a link between humanity and the cosmos, a way to wear the universe on your wrist,” says Pim Koeslag.

This timepiece is a tribute to time itself. From a star’s death to an asteroid’s journey, from its fall to Earth to its transformation into an exceptional watch—each second it measures is an echo of the vast cosmic history it carries.

An Exclusive, Limited Edition for Collectors
The Grand Planetarium Eccentric Meteorite is available in a strictly limited edition, with a maximum of 3 pieces, depending on the avaibility and quality of the rough meteorite material. So far, Christiaan van der Klaauw has been able to produce only 2 pieces from the available material, making this timepiece an exceptionally rare collector’s item. This extraordinary creation offers the unique opportunity to own a fragment of a star, forever marking the passage of time.

Waxing, gibbous, blue: the power of the moon imposes itself on the Earth and even more so, on the seas. Perpetual Moon 38 Night Tide celebrates the fluctuating pull of this celestial body on the water. A large moon disc appears over vast waves. Made of mother-of-pearl and ruthenium, they rise one after the other in a cascade of soft curves. This scene, illuminated by diamonds, celebrates the femininity, elegance and evocative power of Arnold & Son’s watchmaking.

Powerful and plentiful, the waves of Perpetual Moon 38 Night Tide herald heavy seas. In the blue of the night, the tide is at its highest, and so are the rollers. The moon, capricious and triumphant, imposes its will. The gradations of the water are topped with a sparkling foam. Beneath the peaceful light of Selene, the ocean rages on.

Arnold & Son interprets this powerfully symbolic scene through mechanisms and minerals. The astronomical moon complication of Perpetual Moon 38 Night Tide is adorned in mother-of-pearl and ruthenium: a delicate, evocative composition that fully expresses the dial-makers’ expertise. The mother-of-pearl marquetry, ruthenium crystal inlays and abundance of diamonds symbolise the painstaking care lavished on the women's collections of Switzerland’s most English brand.
