OCTOBER 17 2025    |    Novelties

Armin Strom unveils the Mirrored Force Resonance Zeitgeist 1665, a creative interpretation of what a Resonance wristwatch might have looked like centuries ago. This timepiece combines historical horology with modern innovation, celebrating the brand’s milestone achievement of stable and resilient Resonance.

The Zeitgeist features a stainless steel case measuring 43 mm in diameter, paired with an 18K white gold dial in an off-center design. Inside beats the Armin Strom Manufacture Caliber ARF21_ZG, a manual-winding movement with twin-seconds and flyback functionality, offering an impressive 80-hour power reserve. Limited to just 25 pieces worldwide, this exceptional creation pays tribute to the centuries-long pursuit of chronometric consistency, a challenge first explored by Christiaan Huygens in 1665. Armin Strom solved the Resonance Fragility Problem in 2016, making this phenomenon practical for wristwatches.

PULSE GMT Frosted Guilloche Gold: A Masterclass in Modern Mechanical Craftsmanship

Chronoswiss has officially introduced the Pulse GMT Frosted Guilloche Gold, a striking new expression of modern travel time created in its Atelier Lucerne. Housed in a beautifully sculpted 41mm 18ct (5N) gold case, this timepiece seamlessly brings precious materials into the bold, architectural world of the Pulse design family. Redefining the brand’s classic codes with a sharper, sportier attitude, the watch features Chronoswiss’s iconic onion crown, a partially knurled coin-edge bezel, and an exclusive new integrated black rubber strap. This exclusive, modern masterpiece is strictly limited to just 50 pieces worldwide.

At the heart of this timepiece is an innovative, three-dimensional dial that showcases a revolutionary take on a traditional decorative art. For the first time, a hand-guilloché brass surface is refined using a highly precise sandblasting process that directs ultra-fine synthetic corundum particles onto the dial. The result is a shimmering, frosted finish that transforms the geometric guilloché pattern into a crystalline landscape of light and depth. This contemporary backdrop is beautifully contrasted by polished, blue PVD-coated appliques, blued steel screws, and polished, blued steel hands in the brand's signature "Pyramid" shape.

Powering the watch is the Chronoswiss Manufacture Caliber C.6002, an automatic movement developed in partnership with La Joux-Perret that offers a 55-hour power reserve. Designed specifically for global travelers, the movement features a dedicated dual-time-zone module; home time is tracked on a 12-hour disc at 3 o'clock, a second time zone is displayed via a 24-hour GMT disc at 9 o'clock, and central hands sweep the dial to indicate minutes and seconds. The exquisite inner workings of the caliber are visible through a sapphire crystal case back, revealing a skeletonized tungsten rotor, polished escape wheels, and a ruthenium-plated bridge finished with a classic Geneva cut.

The solid 26-piece gold case, weighing 48 grams, balances satin-finished and sandblasted textures with a partly polished bezel, offering 5 bar (50 meters) of water resistance. Secured to the wrist by a black integrated rubber strap and a matching black DLC-coated stainless steel and 5N gold buckle, the watch represents the ultimate expression of the brand’s "Modern Mechanical" philosophy. By contrasting traditional luxury with high-functioning, contemporary materials, the Pulse GMT Frosted Guilloche Gold is engineered as a sophisticated mechanical companion for an ever-moving world.

Arnold & Son Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

Arnold & Son unveils the Perpetual Moon 41.5 Cliff Grey Edition, a poetic tribute to the cliffs of Cornwall and the legacy of John Arnold, the renowned marine chronometer-maker. This limited edition of 28 pieces in 18-carat red gold reflects the brand’s deep connection to celestial navigation and English heritage.

The dial is adorned with the exclusive Stellar Rays motif, a textured pattern that plays with light through layered transparent lacquer. Its Cliff Grey tone evokes the misty British coastline, while the moon phase display—among the largest in watchmaking—glows in mother-of-pearl enhanced with Super-LumiNova. Set against a midnight-blue sky, the moon is surrounded by hand-painted constellations, Ursa Major and Cassiopeia, symbols of guidance and exploration.

The case, measuring 41.5 mm in diameter, is sculpted with refined lugs and a slim bezel that opens up the dial to its full celestial display. On the reverse, a secondary moon-phase indicator allows for precise adjustment of the moon’s age.

Inside, the manually wound A&S1512 calibre offers a 90-hour power reserve and tracks lunar cycles with remarkable precision. So accurate is its mechanism that it would take 122 years of continuous operation to accumulate a single day’s deviation from the actual lunar cycle.

Crafted entirely in-house in La Chaux-de-Fonds, the movement is finished with Geneva stripes, blued screws, and circular graining. The watch is completed with a warm grey alligator leather strap and a matching red gold pin buckle.

The Cliff Grey Edition is a refined expression of Arnold & Son’s dedication to craftsmanship, astronomy, and timeless design.

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.

DANIEL ROTH Unveils Tourbillon Platinum: A Masterpiece of Horological Revival

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.
