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.

Armin Strom Unveils the Tribute 1 Green: A Celebration of Nature’s Elegance

Armin Strom introduces the Tribute 1 Green, a refined dress watch that pays homage to the timeless beauty of nature. Limited to just 50 pieces, this new release brings forest-inspired tones to the brand’s most elegant collection, combining artisanal craftsmanship with modern mechanical innovation.

A Forest-Inspired Masterpiece

The Tribute 1 Green features a striking off-centre dial in forest green, adorned with a hand-engraved grain d’orge guilloché pattern and crisp white Roman numerals. A frosted subdial adds depth and texture, while the green Alcantara leather strap with off-white stitching completes the composition with understated sophistication. The openworked motor barrel, secured by a polished finger bridge in stainless steel, echoes the case design and showcases Armin Strom’s signature fusion of symmetry and mechanical artistry. The 38 mm stainless steel case, with anti-reflective sapphire crystals front and back, ensures optimal clarity and elegance.

Exceptional Performance

At the heart of the Tribute 1 Green is the manual-winding Manufacture Caliber AMW21, offering an impressive 100-hour power reserve. This is made possible by the brand’s patented equal force barrel, designed for efficiency and compactness. Operating at 25,200 vibrations per hour (3.5 Hz), the movement reflects Armin Strom’s technical mastery, with 97% of components produced in-house.

Haute Horlogerie, Hand-Finished

Every Tribute 1 Green is a testament to traditional watchmaking. The case features brushed and polished surfaces, finished entirely by hand. Inside, the movement is decorated with Geneva stripes, circular graining, and a mirror-polished finger bridge, all executed by Armin Strom’s skilled artisans.

True to the brand’s commitment to excellence, each watch is assembled twice—once for mechanical precision and again after decoration—to ensure the highest standards of performance and aesthetics.

Moritz Grossmann Presents the PERPETUAL CALENDAR

To celebrate 17 years since its rebirth in 2008, Moritz Grossmann unveils a horological milestone: the PERPETUAL CALENDAR. This grand complication embodies the brand's philosophy of timeless precision, combining traditional craftsmanship with modern innovation.

The PERPETUAL CALENDAR is engineered to automatically account for the varying lengths of months and leap years, requiring no manual correction until the year 2100. This makes it one of the most technically demanding and revered complications in fine watchmaking.

The dial is a study in symmetry and clarity. A full 1–31 date scale encircles the dial, with a cup-shaped indicator framing the current date. The month and weekday are displayed on subdials at 3 and 9 o'clock, decorated with Azurage finishing. Leap year and day/night indicators are integrated into the subdials. At 12 o'clock, a poetic moon phase display features a mother-of-pearl moon gliding across a goldstone sky.

At the heart of the watch is the newly developed Calibre 101.13, a hand-wound movement based on the 100.1 calibre with an added perpetual calendar module. It comprises 401 components — 211 for the calendar module and 190 for the base movement. The movement features optimised stopwork, an integrated manual winder, and an escape wheel bearing in the barrel bridge. The finishing adheres to traditional Glashütte standards, with untreated German silver plates, raised gold chatons, and hand-engraved details.

All calendar functions can be adjusted via recessed correctors on the case, operated with a dedicated tool. A sum corrector allows for quick synchronization of all indicators after periods of inactivity.

The PERPETUAL CALENDAR is available in three elegant variants: rose gold with argenté dial (Ref. MG-003906), rose gold with anthracite dial (Ref. MG-003907), and platinum with argenté/anthracite dial (Ref. MG-003904). Each model is paired with a hand-stitched dark brown alligator leather strap and a matching prong buckle.

Moritz Grossmann continues to honour its namesake's 19th-century legacy with a commitment to "Schönstes deutsches Handwerk" — the finest German craftsmanship. The PERPETUAL CALENDAR is a testament to this enduring vision, offering collectors a timepiece that is as poetic as it is precise.

Back in sleek anthracite: Armin Strom unveils the One Week Manufacture Edition

Biel/Bienne, Switzerland, 26 June 2024: Following the inaugural redesigned One Week First Edition that made its debut in 2023, Armin Strom unveils a new version of the successor to its first-ever manufacture movement with the One Week Manufacture Edition. The highly architectural openworked movement, housed in a sleek and sporty steel case with an integrated bracelet, is now presented in a range of grey and anthracite hues. Limited to 100 pieces, the One Week Manufacture Edition foregoes colour to bring out the beauty of its uniquely constructed manual calibre.

15 years ago, independent watchmaking brand Armin Strom took a major leap that would forever change its trajectory. Realising that the path to true independence lies in mastering every step of the process, it established its very own manufacture in Biel. A year later, the first timepiece produced by its vertically integrated manufacture was unveiled: the One Week. Entirely developed and manufactured in-house and designed with symmetrical harmony in mind, it stood out thanks to its unique movement architecture featuring two barrels that together provide a seven-day power reserve. This milestone marked the beginning of many new calibres and innovations by the Armin Strom manufacture, showcasing their dedication to the science of movement and garnering the admiration and respect of even the most discerning and seasoned collectors.

The new One Week Manufacture Edition completely reimagines this milestone calibre in line with the brand’s recent bolder, more three-dimensional approach to calibre design, all in a sleek and serene execution that further highlights its ingenuity and uniqueness. The mainplate, bridges and parts, visible on the dial thanks to the openworked movement design, are anthracite PVD coated for a striking look.

As Armin Strom founder Serge Michel notes: “Collectors who missed the opportunity to get a first edition of the redesigned One Week will now have another chance. The Manufacture Edition of the new One Week will be limited to 100 pieces.”

Sporty yet classy, this model exudes calmness and serenity with its anthracite tones and the symmetrical harmony of its in-house movement.

Opus Dakar Sundown: A Two-Tone Symphony of Desert Sunset and Fine Skeletonized Horology

Chronoswiss has officially introduced the Opus Dakar Sundown, a striking new interpretation of the celebrated Opus Dakar that captures the fleeting magic of sunset over the desert. Housed in a distinctive 41mm two-tone case crafted from stainless steel and 18ct red gold, the timepiece masterfully blends the rugged spirit of adventure with refined luxury. The warm glow of precious metal flows seamlessly into the robust steel construction, mirroring the final golden rays dancing across endless dunes. This ultimate celebration of contrasts is beautifully completed by a sand-colored nubuck leather strap that evokes the warm tones of sunlit, weathered terrain.

At the heart of the watch beats the Chronoswiss Manufacture Caliber C.741S, a fully skeletonized automatic chronograph movement that transforms every measurement of time into a visual spectacle. Designed for legibility and visual complexity, the central chronograph seconds hand sweeps the openworked dial in harmony with a 30-minute counter at 12 o'clock and a 12-hour counter at 6 o'clock. A running small seconds display at 9 o'clock provides a constant indication of the movement's heartbeat, while a highly unique, analogue pointer date display at 3 o'clock enhances its everyday practicality.

The skeletonized, CVD-coated brown dial draws inspiration from the rich palette of the desert, where warm tones create a composition that is both timeless and adventurous. By exposing the intricate mechanics beneath the surface, every skeletonized bridge, wheel, and component directly contributes to a captivating, mechanical canvas. The hands are crafted in the elegant Breguet Losange shape and rhodium-plated to ensure striking contrast against the dark, galvanic black perlage of the base plate.

Crafted in solid 23 pieces, the 41mm case features an 18ct red gold bezel with partial knurling, a screw-down case back with a red gold coin-edge ring, and Chronoswiss’s iconic onion crown. The total weight of gold used in this exceptional construction is 21.4 grams. Offering a water resistance of 3 bar (30 meters), the watch is equipped with screw-in lugs utilizing the patented Autobloc system. For over three decades, the Opus collection has embodied the bold spirit of Chronoswiss; the Opus Dakar Sundown brilliantly reimagines this legacy, shaped by craftsmanship and illuminated by one of nature's most spectacular moments.

Mechanical Cool
At the heart of the Delphis Glacier lies an upper dial that creates the stage for the retrograde minute and jumping hour complication.

The monochromatic interplay of textures and tones creates a sophisticated composition that feels both timeless and unmistakably modern.

The Soul of Precision
The Delphis Glacier is powered by the manufacture movement C.6004, a testament to Chronoswiss dedication to precision and innovation. Beyond its visual elegance, the movement ensures outstanding functionality and reliability, transforming the Delphis Glacier into a mechanical sculpture inspired by the silent power of nature. Every detail reflects the serene beauty and resilience of Swiss glaciers. As an homage to the enduring beauty and the purity of ice, the Delphis Glacier is produced in a limited edition of only 50 pieces, making it a rare companion for collectors seeking refined modern mechanics. Discover the silence. Embrace the glacier.

Constant Force Tourbillon 11, yellow gold edition - A celebration of watchmaking ingenuity

The 41.5 mm diameter Constant Force Tourbillon 11 watch in 18-carat yellow gold, released by Arnold & Son as a limited edition of 11, is driven by a hand-wound mechanical movement. Equipped with two barrels to give a 100-hour power reserve, this timepiece was entirely developed and built at the manufacture in La Chaux-de-Fonds. It is fitted with a constant force mechanism visible on the enamel dial and is regulated by a tourbillon that can be seen on the back. The architecture of this calibre is inspired by that of the timekeeping instrument driven by the first tourbillon created by Abraham-Louis Breguet in 1808, based on a chronometer movement designed by John Arnold. This first tourbillon regulator, now in the British Museum, was given to John Roger Arnold by the Paris-based watchmaker in honour of his scientific collaboration and friendship with his father. The Constant Force Tourbillon 11 timepiece, designed to mark the end of the 260th anniversary celebrations of John Arnold’s legacy, pays tribute to the watchmaker’s ingenuity and his close association with Abraham-Louis Breguet.

The greatest watchmakers of the Age of Enlightenment often knew each other. Some of them exchanged views and appreciated each other despite language barriers and political obstacles. And this was the case with John Arnold and Abraham-Louis Breguet. These two watchmakers, undoubtedly the most productive of the second half of the 18th century, forged a friendship that nothing could shake, not even the throes of war between the two countries or the French Revolution. Aware of their respective talents, during Abraham-Louis Breguet’s frequent trips to London between 1789 and 1791, they shared their views and knowledge of the principles of timekeeping, furthering the science of timekeeping, which in their eyes definitely knew no frontiers.
