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.

This year, Angelus is releasing the Chronographe Télémètre as a limited edition of two sets of 25 steel timepieces and a further 15 in 18-carat yellow gold. Measuring 37 mm in diameter, with a vintage-inspired dial and a mono-pusher set into the winding crown, this short-interval timekeeping instrument contains countless tributes to Angelus’ rich history and particularly its speciality in crafting chronographs. Its noble hand-wound mechanism, historical roots and superior finishes give this chronograph a wildly elegant retro aesthetic.

After the Instrument de Vitesse and the Chronographe Médical, the La Fabrique collection welcomes a new masterpiece that recalls the functional and aesthetic history of Angelus. Founded in 1891 in Le Locle by the Stolz brothers, Angelus quickly specialised in alarm clocks, minute repeaters and, above all, chronographs. One of its iconic models already inspired the revival of the Chronodate collection 80 years later.

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.
