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.

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.

Chronoswiss Unleashes the Q-Repeater – A Chiming Masterpiece combining Legacy and Future

Time is not just seen—it is heard.

Chronoswiss presents the Q-Repeater Scream and Q-Repeater Blue Note, two extraordinary Quarter Repeater timepieces that merge the sonic beauty of timekeeping with cutting-edge mechanical architecture. The watchmakers from Lucerne have created a bold reinvention of sound, design, and independent watchmaking deeply rooted in Chronoswiss history. Housed in a Grade 5 titanium case, these 42mm skeletonized masterpieces reveal the intricate mechanisms behind their chiming complication. Every press of the 10 o’clock pusher activates the mesmerizing quarter repeater function, where hammers strike to audibly indicate the hours and quarter-hours, making time a true sensory experience. At its core lies a legacy movement, rooted in the vision of Chronoswiss founder Gerd-Rüdiger Lang. First introduced in the 1990s and exclusively produced for Chronoswiss, this legacy caliber has been taken from our archives, meticulously restored, refined, and reborn in the Atelier Lucerne, making these two timepieces an extraordinary link between the past and the future.

What the watchmakers of Lucerne have achieved here is the ultimate evolution—the heart beats with the legacy of the past, carrying its passion and memories, while the body is Modern Mechanical, engineered for the next century and beyond.

Q-Repeater Scream – A Chiming Rebel
This is not your grandfather’s repeater. The Q-Repeater Scream is a wild, untamed spectacle—combining bold design and mechanical precision unlike anything in watchmaking. The multi-level dial is a skeletonized stage and at the same time part of the movement, where CVD-coated bridges in electric blue, orange, and purple hold the Paraiba green minute ring, the floating hour, as well as the small seconds rings. At 1 o’clock, the heart of this spectacle is fully visible: the striking hammers, set to release a mechanical rock concert at the press of a button.

As you can tell by the name already, it’s not just about what you see. It’s about what you hear. Every chime is a scream of innovation, breaking free from the traditions of classical repeater watches. Even the legacy movement itself becomes part of the gig, holding the Super-LumiNova blocks and hand-guilloché bridges—one of which moves when the mechanism is activated, adding to the dynamic energy of the dial. The watchmakers of Lucerne refer to the glowing ceramic blocks as “chicken heads”, a nod to the iconic amplifier knobs found on rock concert stages—designed to crank up the sound and electrify the crowd.

Caged in 42mm of titanium, the Q-Repeater Scream is limited to just 25 pieces. As only very few of the legacy movements exist this might be the final tour of the band. Each piece is a testament to mechanical defiance and unfiltered artistry. A Quarter Repeater like no other— built for collectors who dare to embrace the wild side of watchmaking.

Q-Repeater Blue Note – The Sound of Elegance
For those who seek a symphony rather than rock n roll, the Q-Repeater Blue Note takes a more refined yet equally innovative approach. Inspired by the expressive power of jazz and blues, the navy blue CVD-coated skeletonized dial and bridges which are part of the movement, play on contrasts with a silver hour ring and luminous white Super-LumiNova markers, creating a harmonious composition of mechanics and design.

In music, a blue note is an altered pitch—intentionally deviating from the standard, creating a sound that is richer, deeper, and full of soul. One could say – the Chronoswiss way of making watches – and music. The Q-Repeater Blue Note embodies this philosophy, blending traditional watchmaking with a contemporary edge, offering a timeless yet unconventional melody of time.

Like the Scream, the Blue Note features the multi-level regulator dial, a fully visible quarter repeater mechanism, and a restored historical movement, revised and refined by thewatchmakers in Lucerne. It is a timepiece that doesn’t just mark time—it composes it.

Time Reimagined, Sound Reinvented
The Q-Repeater Scream and Q-Repeater Blue Note stand as testaments to Chronoswiss’ relentless drive to push boundaries. With only 25 pieces per model, these Quarter Repeaters are more than just rare; they are audible declarations of mechanical mastery.

This is not just a watch. It is an experience. A fusion of sound and time, crafted for those who appreciate the extraordinary. Chronoswiss has never followed the expected path. The future of independent watchmaking starts here—with a chime.

Greubel Forsey Launches the Nano Foudroyante: A New Chapter in Watchmaking Innovation

Greubel Forsey has officially released the Nano Foudroyante, a groundbreaking timepiece that blends cutting-edge nanomechanics with refined craftsmanship. Limited to just 22 pieces, this watch marks a major milestone for the brand, evolving from its earlier Experimental Watch Technology (EWT) concept into a fully developed and independent creation.

The Nano Foudroyante is crafted entirely in white gold and features a rhodium-finished dial with a blue minute track, blued steel hands, and a white foudroyante dial for enhanced legibility. A blue textured rubber strap completes the look, giving the watch a modern and sporty edge.

What sets this timepiece apart is its use of nanomechanics—a revolutionary approach that allows the foudroyante complication to operate using just 16 nanojoules of energy per jump. That’s 1,800 times less than traditional designs. The complication divides each second into six parts, with a red-treated hand rotating once per second, driven directly by the balance wheel. There’s no traditional gear train, just a series of ultra-efficient, low-inertia wheels.

The Nano Foudroyante also features Greubel Forsey’s first flying tourbillon, with the foudroyante dial always facing twelve o’clock for easy reading. Despite its complexity—428 components in total—the movement fits into a compact 37.90mm case, making it the smallest Greubel Forsey watch ever made.

This release is a bold statement of innovation and intent, offering collectors a rare opportunity to own one of the most advanced mechanical watches ever created..
