Lunar Chronograph Aurora

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.

Arnold & Son unveils the final chapter of its Constant Force 11 collection with the Constant Force Tourbillon 11 Platinum Edition, a limited series of just 11 pieces. This exceptional timepiece celebrates 260 years of horological heritage, paying homage to the legendary friendship between John Arnold and Abraham-Louis Breguet.

Crafted in platinum (Pt950), the 41.5 mm case houses a dial of hand-guilloché tremblé engraving in 18K yellow gold, inspired by the fern-covered moors of Tintagel, Cornwall—Arnold’s birthplace and the mythical land of King Arthur. The white opal subdial and visible constant force mechanism add depth and elegance.

Powered by the A&S5219 manual winding calibre, the watch features a constant force mechanism, one-minute tourbillon, and true-beat seconds. The engraved plate reads: "To the revered memory of John Arnold and Abraham-Louis Breguet. Friends in their time, legendary watchmakers always."

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.

Moritz Grossmann proudly unveils the TREMBLAGE Green, a limited edition timepiece that redefines elegance through heritage craftsmanship and a bold new aesthetic. Available in rose gold and white gold, with only 8 pieces of each, this extraordinary watch is a tribute to the art of traditional engraving and the timeless beauty of horological design.

At the heart of the TREMBLAGE Green lies a dial crafted from German silver, meticulously hand-engraved using the rare tremblage technique. This centuries-old method creates a fine, matte texture that diffuses light with a soft, meditative glow. The dial is finished in a deep, complex green—symbolizing renewal, harmony, and depth—making it a standout piece that remains understated and refined.

Encased in a 41 mm case of 750/000 rose or white gold, the watch is powered by the in-house calibre 100.1, a hand-wound movement visible through a sapphire crystal case back. Every component is hand-finished, from the Glashütte ribbing and polished bevels to the engraved balance cock. The watch features hours, minutes, and a small seconds display with a stop-second function, all operated via a gold crown and lateral pusher.

Completing the look is a hand-stitched dark brown alligator leather strap, offering both comfort and sophistication. The TREMBLAGE Green is not just a timepiece—it is a celebration of “Schönstes deutsches Handwerk” (the finest German craftsmanship), brought to life with modern sensibility and timeless appeal.
