A Star Fragment, Guardian of Time: The Grand Planetarium Eccentric Meteorite

APRIL 01 2025 | Novelties

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.

Longitude Titanium - High-sea watchmaking

Arnold & Son, a benchmark in classic fine watchmaking, is exploring uncharted territory on the map of horology. Longitude Titanium is a sports-chic COSC-certified chronometer with a 42.5 mm titanium case. The dial of Longitude Titanium is vertical satin-finished in a continuation of the bracelet’s finish, which is subtly intersected by the polished edges of its links. With a power-reserve display at 12 o’clock and an imposing seconds counter at 6 o’clock, Longitude Titanium pays tribute to John Arnold’s marine chronometers, his revolutionary vision and his decisive role in calculating longitude at sea.
The aesthetics and construction of John Arnold’s marine chronometers were necessarily classic and functional, and were adapted to the harsh conditions of the high seas. Longitude Titanium, a contemporary interpretation of the great English watchmaker’s work, coherently combines this naval heritage with a refined design and highly resistant materials. The movement’s ‘chronometer’ certification is an essential addition to this scene, with its historical ties to Arnold’s creations and his quest for accuracy.

A single shade of grey - Chronodate Titanium, Magnetic Silver Edition

The omnipresent grey of titanium extends into the sunray-brushed grey of the "Magnetic Silver" dial. Chronodate Titanium expresses its technical sophistication in an ensemble where deep black contrasts with a hint of red. With this ultra-sporty, understated and intense new colour scheme, Chronodate Titanium catches the eye, fixes it and draws it towards the horizon.

Angelus introduces a new shade of its self-winding chronograph with peripheral date. Chronodate welcomes the silver-grey "Magnetic Silver" in a tone-on-tone effect. The harmonious blend between titanium case, titanium bracelet or black rubber strap, rhodium-plated hands and the dial surface creates a technical monochrome impression. This grey continues into black, revealing the movement container and then the carbon composite push-pieces. This black ensemble culminates in the two counters, one a 30-minute chronograph totaliser and the other with a small seconds.

Chronodate is a fusion of two different styles: Angelus, the historic brand and its Swiss watchmaking heritage, and Angelus, the technical, modern brand with a penchant for complications. With this colour combination, the house presents the most striking version of this chronograph collection.

The HM Pietersite: A Tribute to the Spirit of Exploration and the Art of the Ultra-Thin

Arnold & Son presents two new evocative versions of its ultra-thin HM model, featuring dials crafted from Namibian pietersite. Often called the "stone of storms," this decorative mineral belongs to the chalcedony family and was first discovered by Sid Pieters in the early 1960s. Each unique dial displays delicate, swirling patterns that recall the turbulent skies and foaming waves of Cornwall, the English birthplace of founder John Arnold. This design pays tribute to the ingenuity of the legendary watchmaker while celebrating the spirit of those who maintain their course in a challenging world.

The designation "HM" was intentionally chosen to reflect the watch's focus on displaying only hours and minutes, while simultaneously serving as a historical nod to the British Royal Navy. In naval tradition, HM stands for "His or Her Majesty’s," a title that appeared in the 17th century and was later formalized as HMS. By transposing this reference to watchmaking, Arnold & Son connects the precision of modern horology with England's maritime history, specifically the era when John Arnold’s marine chronometers enabled the exploration of new lands.

Encased in a choice of 18-carat red gold or stainless steel, the HM Pietersite is a masterpiece of elegance and restraint. The case measures a refined 39.5 mm in diameter with a remarkably slim profile of just 7.82 mm. To complement the dreamlike, diaphanous patterns of the pietersite dial, the timepiece is paired with a matte ink-blue alligator leather strap and a traditional pin buckle crafted from the same metal as the case. These limited editions are produced in extremely small quantities, with only 8 pieces available in red gold and 18 in steel.

At the heart of this timepiece lies the ultra-thin, in-house A&S1001 manual-winding calibre. Visible through a sapphire crystal case back, the movement is a showcase of luxury finishing, featuring a rhodium-plated main plate with circular graining and bridges adorned with radiating Côtes de Genève. Despite its slender height of only 2.70 mm, the movement offers exceptional performance with a generous 90-hour power reserve. Every detail, from the snail-finished wheels to the blued screws with polished heads, reflects the most exacting standards of Swiss watchmaking.

Perpetual Moon 41.5 Platinum, Fern Green edition - Clear Skies

Moonlight illuminates a botanical green dial. The “Fern Green” version of Perpetual Moon 41.5 borrows the cool tones of the moon. The paleness of the platinum, the freshness of the fern green, and the midnight blue of the sky create an original flow of colours.

Maturity, diversity and mechanical exclusivity: the Perpetual Moon collection is constantly being enriched with new creations, consistently reaffirming the watchmaking and artistic talents of Arnold & Son. Following two other editions, one with salmon pink accents and another in sky blue, Perpetual Moon 41.5 Platinum is now available in this limited fern green version of 28 timepieces.

Its hue is inspired by the unique colour of the fern, an undergrowth plant found in abundance in the English gardens of Cornwall, the county where John Arnold was born.

Armin Strom introduces the Orbit Purple

With the Orbit, we’ve created the world’s first on-demand pointer-date on a bezel. And in doing so, we didn’t just rethink a complication — we introduced a whole new experience. Most watches just force the date on you. The date function is always present — whether you like it or not, it shifts at midnight, ticking off another day. The Orbit? It’s different. It only displays the date when you ask.

Moritz Grossmann GMT Guilloche Limited Edition Dual Time Zone Watch with Hand-Guilloché Dial

The Moritz Grossmann GMT Guilloche is a celebration of global exploration and fine German watchmaking. Inspired by the colors of nature and the rhythm of travel, this dual time zone watch is available in two striking dial variants: matte green, evoking serene meadows and hidden coves, and vibrant orange, reminiscent of the glow of a setting sun.

Dual Time Functionality

Designed for the modern traveler, the GMT Guilloche features a 24-hour time zone ring encircling the dial. A distinctive arrow-shaped hand tracks a second time zone, offering intuitive day-night orientation. Local time is displayed via central hour and minute hands, with a small seconds subdial at 6 o’clock. A dedicated crown at 10 o’clock allows seamless adjustment of the second time zone without affecting the main time.

Masterful Craftsmanship

Each dial is hand-engraved using the traditional guilloché technique, creating intricate geometric patterns that shimmer with light. The green dial is paired with blued steel hands, while the orange dial features polished steel hands—both handcrafted in Glashütte.

Engineered for Precision

Inside the watch beats the calibre 100.8, a manually wound movement crafted in-house and regulated in five positions. It features 253 components, 26 jewels, and signature Grossmann innovations including the 2/3 plate with raised gold chatons, cantilevered balance cock with micrometer screw, and a separately removable winding mechanism. The second time zone mechanism is seamlessly integrated on the dial side, ensuring precision and harmony.

Limited Edition

Encased in stainless steel and fitted with a hand-stitched black alligator leather strap, each GMT Guilloche model is strictly limited to 8 pieces worldwide, making it a rare collector’s item.

Discover the Art of Glashütte

Moritz Grossmann continues to honor its founder’s legacy by blending traditional craftsmanship with modern innovation. The GMT Guilloche is a wearable work of art—an invitation to wear the world on your wrist.
