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.

About Christiaan van der Klaauw
Christiaan van der Klaauw is one of the most prestigious watchmaking houses in the Netherlands, specializing in astronomical watches. Founded in 1974, the brand has distinguished itself by its ability to integrate astronomical complications innovatively and artistically into high-precision timepieces. The Grand Planetarium eccentric model is one of its most iconic Grande Complication, representing the quintessence of art and science.

Released initially with a grey dial and then with a Lever de Soleil color dial, the C by Romain Gauthier Titanium Edition Bracelet is now featured with two new dials: a three-dimensional straight grained structured dial in Grade 5 black titanium with white details and a black sapphire openwork dial with blue and white accents.

The three-dimensional straight grained black titanium dial provides an even more assertive character with its textured surfaces. The sharp contrast between the white details and the dark background enhances the time indications. This dial embodies a distinctly modern design while maintaining excellent readability, even in low-light conditions, thanks to the use of Super- LumiNova on the indexes, numerals, and hands.

As for the sapphire openwork dial, it reveals the intricate components of the movement, showcasing the brand's sophisticated watchmaking engineering and artisanal craftsmanship. This openwork design creates a captivating interplay between transparency and structure, transforming the watch into a true technical and aesthetic masterpiece. When Romain launched the first edition of C by Romain Gauthier in 2021, it was clearly stated that this new caliber would lead the brand to new horizons. One year later, a new door has been opened with the arrival of the brand's first metal bracelet.

Sober and contemporary, propitious to variations and adaptations, C by Romain Gauthier was an obvious choice for the creation of a metal bracelet. The desire of modernity, comfort and ergonomic already initiated during the conception of the first edition, reinforced the development of this integral timepiece on a titanium bracelet - light, resistant, modern and sophisticated. Aesthetically, it was important to Romain that the bracelet and the watch become one. As he said: "The bracelet is the case, and the case is the bracelet". This desire is reflected in the fusion of these two elements, a timepiece as a whole that cannot be dissociated.

In keeping with Romain's vision - The Evolution of Tradition - this new technical and contemporary element requires a high level of craftsmanship and hand finishing. Each link is composed of hand-polished and satin-finished surfaces that play with the light and reflect the technical nature of the bracelet and the piece in general.

A timepiece focused on the essential—yet anything but ordinary.

Chronoswiss proudly introduces the Small Second, the beginning of a new family in the Modern Mechanical collection. The vision? To create a bold mechanical timepiece, stripped of excess yet rich in craftsmanship and detail.
