Arnold & Son proudly presents the Longitude Titanium 5°W Edition, a timepiece inspired by the marine chronometers crafted by John Arnold in the late 18th century. These instruments revolutionized navigation and played a pivotal role in the British Navy’s mastery of the seas.

This limited edition of 38 pieces combines grade 5 titanium with an 18K red gold bezel ring, echoing the elegance of historical chronometers. The Lizard Point Grey dial, with its vertical satin finish, evokes the stormy hues of the North Atlantic near Lizard Point—the southernmost tip of mainland Great Britain at 5° west longitude.

Inside beats the A&S6302 calibre, an in-house automatic movement certified by the COSC as a chronometer. It offers a 60-hour power reserve, a power-reserve indicator at 12 o’clock, and a small seconds subdial opposite. Through the sapphire case back, the palladium-plated bridges and skeletonized 22K red gold oscillating weight—engraved with a ship and sextant motif—reveal the artistry of Arnold & Son.

Water-resistant to 100 meters, the Longitude Titanium 5°W features an interchangeable strap system, allowing effortless transition between an anthracite grey alligator leather strap and a titanium bracelet.

Known for bold evolutions of mechanical wristwatches and daring designs, Chronoswiss unveils its latest creature: the ReSec Snake. Slithering between heritage and rebellion, this timepiece is a hypnotic blend of color, contrast, and kinetic energy — proof that modern mechanical watchmaking still has a few fangs to bear.

The Snake’s Bite

The ReSec Snake coils into view within a 42mm titanium case, coated with a mesmerizing color-changing PVD-coating that shifts from emerald green to turquoise, depending on the light. It’s not just a case — it’s iridescent armor, capturing the reptilian allure of a serpent in motion. Paired with a contrasting white rubber strap, the Snake wraps around the wrist with smooth, tactile elegance.

But the true venom lies beneath the sapphire crystal. A green CVD-coated dial, hand-guillochéd in the Lucerne Atelier, pulses with depth and hypnotic texture. It’s a dial that doesn’t just tell time — it seduces it.

Take a closer look, and the architecture reveals itself: the iconic 3D regulator layout of the ReSec series slithers across the dial, framed by green hour and minute rings and a retrograde second display, like the flick of a serpent’s tongue. Underneath, the exposed gear train glimmers in contrasting tones — a mechanical exoskeleton that moves with silent precision.

Fangs Beneath the Surface

Powering this cold-blooded beauty is the Chronoswiss Manufacture Caliber C.6005, featuring a 55-hour power reserve, ruthenium-plated finishing, and a radial Côtes de Genève motif. It’s mechanical watchmaking at its sharpest: sleek, silent, and engineered to strike.

Limited. Lethal.

Only 100 pieces of the ReSec Snake will ever exist — a rare breed for collectors with a taste for the untamed. The ReSec Snake is a statement: of daring, of detail, and of defiance — proving once again that at Chronoswiss, we don’t follow rules. We shed them.

Drawing inspiration from the natural beauty and architectural heritage of Burgdorf, Armin Strom introduces the Tribute 1 Sandstein, a limited edition timepiece that blends Swiss tradition with modern refinement. With only 50 pieces available globally, this elegant watch pays tribute to the region’s iconic sandstone and the brand’s artisanal roots.

Encased in a 38 mm stainless steel case with alternating brushed and polished finishes, the Tribute 1 Sandstein features a warm sand-toned off-centre dial adorned with a grain d’orge guilloché pattern and Roman numerals. A frosted subdial and matching sand Alcantara strap complete the harmonious design.

At its heart beats the in-house Caliber AMW21, a hand-wound movement offering an impressive 100-hour power reserve. The visible motor barrel, held by a mirror-polished finger bridge, adds a modern technical flair while honoring traditional Swiss watchmaking values.

Through sapphire crystals on both sides, the movement reveals Armin Strom’s signature hand-finishing: hand-bevelled bridges, black-polished screws, Geneva stripes, and circular graining. Each watch is assembled twice, ensuring mechanical precision and aesthetic integrity.

Arnold & Son has unveiled its new "Perpetual Moon 41.5 Steel Colours of the Moon" collection, a series of highly exclusive, limited-edition timepieces inspired by the changing celestial hues of Earth's natural satellite. Detailed in the official release document, "ENG_A&S PM 41.5 Steel Colours of the Moon.doc", the collection features three distinct versions—the Blue Moon, Golden Moon, and Red Moon—each celebrating a unique atmospheric or seasonal phenomenon that alters the Moon's appearance and has fascinated civilisations throughout history.

Reinterpreting the iconic Perpetual Moon collection, these new models introduce a 41.5 mm stainless-steel case that balances horological exclusivity with everyday versatility. In a watchmaking first, Arnold & Son has applied a pioneering Physical Vapour Deposition (PVD) treatment directly onto precious mother-of-pearl. This innovative process creates deep, shifting reflections across the dials and moon-phase skies, showcasing the natural organic layers of the material with patterns that recall the flowing grain of Damascus steel.

The astronomical precision of the moon phase is enhanced by Super-LumiNova hidden beneath the colored mother-of-pearl moon disc, accompanied by hand-painted luminescent constellations of Cassiopeia and Ursa Major—a poetic tribute to historical mariners who relied on them for navigation. Bringing this celestial mechanics to life is the in-house A&S1512 manual-winding calibre. This movement provides a generous 90-hour power reserve and displays meticulous luxury finishes, including radiating Côtes de Genève and a secondary moon-phase indicator, all visible through the sapphire crystal case back.

Each of the three references is paired with a matching hand-stitched alligator leather strap and secured with a stainless-steel pin buckle. To maintain their extreme exclusivity, production is strictly limited to just 18 pieces per version.
