Greubel Forsey GMT Balancier Convexe

DANIEL ROTH proudly presents the Tourbillon Platinum, a timepiece that pays homage to the brand’s rich heritage and its founder’s enduring passion for the tourbillon complication. This exceptional creation is inspired by the 1988 reference C187 and reinterprets it with modern refinement, artisanal craftsmanship, and a noble platinum case.

The signature double-ellipse case, now crafted in platinum, measures 38.6 x 35.5 mm and is just 9.2 mm thick. It houses a hand-guilloché dial made of solid white gold, finished in anthracite and accented with a sterling silver chapter ring. The dial’s linear guilloché pattern is executed by a single Maître Guillocheur over three days, reflecting the brand’s commitment to traditional métiers d’art.

Inside beats the DR001 calibre, a manually wound movement developed by Michel Navas and Enrico Barbasini at La Fabrique du Temps Louis Vuitton. Comprising 206 components, it offers an 80-hour power reserve and operates at 3Hz. The movement is entirely hand-finished, including hidden components, and features a triple-arm seconds hand—a nod to Daniel Roth’s original design language.

The Tourbillon Platinum is the third model in the brand’s rebirth, following the Tourbillon Souscription and the rose gold edition. It offers a more contemporary aesthetic while remaining faithful to the brand’s DNA of mechanical excellence and elegant restraint.

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.

The beauty of many millennia of fossilisation. The fiery shades of conifers in autumn. The radiant translucency of resin. Baltic amber reveals the richness of life, the complexity of nature and the magic of the passing of time. This rare and challenging fossilised resin is showcased in all its splendour on HM Steel Amber. It adorns the almost bare dial, framed by an ultra-thin steel case. Arnold & Son plays a new hand and continues to innovate in the field of exceptional materials.

Arnold & Son is opening a new chapter in its collections of materials. After timepieces featuring charoite, specular hematite and even meteorite, a one-off piece from the Double Tourbillon collection played host to the glistening pale yellow hues of Baltic amber for the very first time. Difficult to source and challenging to work, it took the house several months to find the precious fossil needed to produce the 38 HM Steel Amber timepieces.
