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.

Traditional Watchmaking Elevated: DANIEL ROTH Introduces the Extra Plat Platinum

In the refined sphere of independent watchmaking, DANIEL ROTH has introduced a sophisticated new expression of its Extra Plat collection, elevating the rarity of the line while retaining an understated and disciplined elegance. Rooted in the firm belief of its legendary founder that a thin dress watch represents the ultimate epitome of functional elegance, this model is meticulously designed from the ground up to balance modern sophistication with time-honored craft. Cloaked in 950 platinum—a noble metal long synonymous with rarity and traditional savoir-faire—the watch establishes a quiet yet unmistakable presence on the wrist that will immediately resonate with serious connoisseurs.

The defining silhouette of this timepiece remains the signature double-ellipse case, an iconic geometry originally created by master watchmaker Daniel Roth to beautifully frame complex horological mechanisms. To complement this distinctive shape, downward-sloping lugs have been elegantly integrated to ensure optimal wrist comfort while providing a handsome architectural contrast against the light-tan calfskin leather strap. The dial base is forged from solid white gold, displaying a mesmerizing pinstripe guilloché texture executed entirely by hand using a traditional rose engine. Each line is individually carved with masterful control over depth and spacing, beautifully bordered by a gold minute disc finished with a classic filet sauté edge and sharp black typography.

Beneath this stunning facade lies the core of the timepiece: the ultra-thin, hand-wound manufacture Calibre DR002, fully developed and assembled at La Fabrique du Temps Louis Vuitton under the expert guidance of master watchmakers Michel Navas and Enrico Barbasini. Tasked with striking the perfect balance between chronometric precision and a generous power reserve within a slim 3.1 mm structure, the watchmakers increased the movement's frequency to 4 Hz. To sustain this high frequency without sacrificing energy efficiency or structural stability, the calibre incorporates a specially refined balance wheel featuring a variable-inertia geometry and adjustable counterweights.

An open sapphire caseback reveals the true artistic discipline of the manufacture, where technical engineering and aesthetic restraint seamlessly converge. The movement's bridges are decorated with demanding hand-finishing details, most notably the internal angles which are rendered in a rare, rounded bercé form. Requiring at least twice the execution time of a standard flat bevel, this traditional decoration involves polishing a precise curved radius along the edges to create a brilliant, uniform profile. Shaped and hand-polished in-house using a traditional cabron tool, these components reinforce the brand's unwavering commitment to its guiding philosophy: "La Montre Objet d'Art".

Armin Strom Unveils the Tribute 1 Green: A Celebration of Nature’s Elegance

Armin Strom introduces the Tribute 1 Green, a refined dress watch that pays homage to the timeless beauty of nature. Limited to just 50 pieces, this new release brings forest-inspired tones to the brand’s most elegant collection, combining artisanal craftsmanship with modern mechanical innovation.

A Forest-Inspired Masterpiece

The Tribute 1 Green features a striking off-centre dial in forest green, adorned with a hand-engraved grain d’orge guilloché pattern and crisp white Roman numerals. A frosted subdial adds depth and texture, while the green Alcantara leather strap with off-white stitching completes the composition with understated sophistication. The openworked motor barrel, secured by a polished finger bridge in stainless steel, echoes the case design and showcases Armin Strom’s signature fusion of symmetry and mechanical artistry. The 38 mm stainless steel case, with anti-reflective sapphire crystals front and back, ensures optimal clarity and elegance.

Exceptional Performance

At the heart of the Tribute 1 Green is the manual-winding Manufacture Caliber AMW21, offering an impressive 100-hour power reserve. This is made possible by the brand’s patented equal force barrel, designed for efficiency and compactness. Operating at 25,200 vibrations per hour (3.5 Hz), the movement reflects Armin Strom’s technical mastery, with 97% of components produced in-house.

Haute Horlogerie, Hand-Finished

Every Tribute 1 Green is a testament to traditional watchmaking. The case features brushed and polished surfaces, finished entirely by hand. Inside, the movement is decorated with Geneva stripes, circular graining, and a mirror-polished finger bridge, all executed by Armin Strom’s skilled artisans.

True to the brand’s commitment to excellence, each watch is assembled twice—once for mechanical precision and again after decoration—to ensure the highest standards of performance and aesthetics.

Armin Strom extends its golden era with the One Week Skeleton Rose Gold, a new interpretation of its architectural One Week design. This fully skeletonised masterpiece reveals the depths of its mechanics, paying tribute to Mr. Armin Strom’s pioneering artistry in skeletonisation—a craft at the heart of the brand’s philosophy and heritage.

For the first time, the in-house calibre appears in a solid 18K rose gold case, enriching the collection with a warmer character. Rose gold-coloured finger bridges, hands, and applied indexes mirror the tone of the case, while a sleek black textile strap provides a refined modern contrast. Measuring 41 mm in diameter, the case remains compact and ergonomic, while its skeletonised architecture gives the watch a distinctive presence—a harmonious balance of technical craftsmanship and precious metal elegance.

Seven Days of Precision
At its heart lies the hand-wound Calibre ARM21-S, a reinterpretation of Armin Strom’s first in-house calibre. Two mainspring barrels work in series to deliver a steady flow of energy for seven days, wound by two ratchet wheels visible on the dial side—a distinctive Armin Strom signature. Operating at 3.5 Hz, the calibre ensures consistent precision and stability in daily wear.

Inspired by historical pocket watches, the conical power reserve mechanism is complemented by a 3D power reserve indicator, displaying remaining energy with exceptional clarity. Central hours and minutes keep the display symmetrical, while a skeletonised small seconds at 9 o’clock adds an engaging sense of motion.

Transparency in Gold
Every component of the Calibre ARM21-S is decorated by hand, reflecting Armin Strom’s dedication to traditional craftsmanship. Hand-polished bevels, Geneva stripes, circular graining, and finely finished screw sinks demonstrate uncompromising attention to detail. Each One Week is assembled twice—a hallmark of the brand’s commitment to mechanical precision and aesthetic integrity.

Limited to just 50 pieces worldwide, the One Week Skeleton Rose Gold continues Armin Strom’s modern gold chapter—a celebration of mechanical transparency, precision, and craft.

CARVED BY TIME. CONNECTED BY HERITAGE. Chronoswiss Unveils the Small Second Stone Collection

Chronoswiss proudly unveils its latest masterpiece within the Modern Mechanical era, introducing the Small Second Stone Collection featuring stunning natural stone dials. The Small Second Jasper and Small Second Serpentine models pay tribute to the brand's remarkable journey, bridging its origins in Munich with its creative home in Lucerne. By uniting millions of years of geological history with over four decades of independent watchmaking, these timepieces transform nature itself into an exquisite canvas for mechanical artistry.

The narrative behind these watches stretches back millions of years before the creation of the first mechanical movement. The Small Second Serpentine features a striking green stone sourced from the region surrounding Zermatt and the Matterhorn, representing an ancient ocean floor pushed upward during continental collisions to form the Alps. Meanwhile, the Small Second Jasper utilizes the painted stone of the Earth from Germany, honoring the foundational roots of founder Gerd Rüdiger Lang and connecting with the historic stone-cutting traditions of Idar-Oberstein.

Because these creations rely on genuine natural minerals, every single dial is entirely unique. The Small Second Jasper captivates the eye with a landscape of warm beige, brown, and ivory tones housed in a refined stainless steel case, while the Small Second Serpentine presents a vivid green dial paired with a sophisticated two-tone stainless steel and 18-karat red gold case. Limited to just 50 pieces each worldwide, these wristwatches offer collectors an exclusive expression of organic beauty and sophisticated luxury.

At the heart of these models lies the Chronoswiss Manufacture Caliber C.6000, an automatic movement that delivers an approximate 55-hour power reserve. The movement features a skeletonized tungsten rotor and Geneva-striped bridges, which can be admired through the sapphire crystal case back. Housed within a 40-millimeter case featuring the signature fluted bezel and onion crown, the design maintains visual balance by placing the hand-guilloched small seconds subdial at the 9 o'clock position.

The Small Second Stone Collection stands as a pure and captivating expression of the Chronoswiss design philosophy. Marrying meticulous craftsmanship with exceptional horological engineering, these timepieces invite connoisseurs to wear a fragment of geological history on their wrists. Each watch successfully honors the past while pushing the boundaries of contemporary independent watchmaking into an exciting future.
