Armin Strom Unveils the Gravity Equal Force Ultimate Sapphire Rose Gold — A Masterpiece of Mechanics and Elegance

JUNE 18 2025    |    Novelties

Independent Swiss watchmaker Armin Strom proudly presents the Gravity Equal Force Ultimate Sapphire Rose Gold, a timepiece that exemplifies the brand’s commitment to horological innovation, artisanal craftsmanship, and visual harmony.

Encased in 18K rose gold, this limited-edition watch features a sculptural movement architecture that plays with tone and texture. A brown guilloché mainplate, rose gold-colored bridges, and a floating off-centre sapphire dial create a refined and coherent composition. The watch is paired with a matte brown nubuck leather strap, adding an earthy elegance to the overall aesthetic.

At the heart of the timepiece is the Caliber ASB19, Armin Strom’s groundbreaking automatic movement. It incorporates a patented stop-work declutch mechanism and Geneva cross within the barrel, ensuring consistent torque delivery throughout its 72-hour power reserve. A micro-rotor enables efficient winding while preserving the symmetry and visibility of the movement — a hallmark of Armin Strom’s design philosophy.

Every component, visible or hidden, is hand-finished to haute horology standards. Techniques such as beveling, straight-graining, perlage, Geneva stripes, and black-polished screws are applied with precision and care. The mainplate features a “grain d’orge” guilloché pattern, crafted by master artisan Kari Voutilainen using a traditional hand-operated machine.

This exceptional timepiece is limited to just 25 pieces per year, making it a rare and radiant statement in the world of independent watchmaking. It is a testament to Armin Strom’s philosophy: Mechanics First. Always.

Chronoswiss Unveils the Neo Digiteur Chronos: Time Carved in Solid Gold

Chronoswiss is proud to announce the launch of the Neo Digiteur Chronos, an extraordinary evolution of one of the brand’s most unconventional creations. Inspired by the original handless Digiteur introduced in the early 2000s by founder Gerd-Rüdiger Lang, this edition transforms a radical mechanical rebellion into a sculpted gold masterpiece. Housed in a tailored 48mm x 30mm rectangular case made from solid 5N gold (65g) and completely hand-engraved at the Atelier Lucerne, the watch depicts Chronos—the ancient Greek god of time—holding a mythological hourglass.

Rather than utilizing a traditional dial, the watch seamlessly integrates three precise apertures into the sculpted gold scene. The passage of time is visually poetized: the jumping hour appears in Chronos’ scythe at 12 o'clock, the sweeping minute disc flows through the upper chamber of the hourglass, and the continuous seconds rotate below in the lower chamber. Encircling the entire case and printed inside the black nubuck strap is a classic Greek meander pattern, an ancient symbol representing eternity and the infinite flow of time

At the heart of this handless digital regulator is the hand-wound Chronoswiss Caliber C.85757, equipped with an in-house developed jumping hour module. Visible through the rectangular sapphire crystal caseback, the movement operates at 3 Hz with a 48-hour power reserve and features exquisite rhodium plating, radial Côte de Genève, and hand-guilloché wheel bridges executed in Lucerne. Completed with a 5N gold pin buckle (4g), every technical detail underscores the brand's commitment to expressive high horology.

Strictly limited to only 33 pieces worldwide, each Neo Digiteur Chronos requires weeks of painstaking hand engraving, ensuring no two pieces are ever completely identical. As a rare fusion of ancient mythology, traditional hand craftsmanship, and avant-garde watchmaking, this collector’s creation represents a mechanical myth carved in gold. The Neo Digiteur Chronos is now available for inquiry through authorized Chronoswiss retailers and official channels.

The Architecture of Two Worlds: Chronoswiss Unveils the PULSE GMT Collection

Chronoswiss marks a definitive leap into the future of independent watchmaking with the introduction of the PULSE GMT, a collection that represents one of the most progressive chapters in the brand's history. Inspired by the mechanical spirit of the 1999 Tora icon, this new series redefines traditional design codes through a radically modern lens while maintaining the brand's independent spirit. The collection is built specifically for global travelers and collectors who move between continents and time zones, requiring a sophisticated mechanical companion.

The PULSE GMT features a bold, sculptural case construction that seamlessly integrates the first full metal bracelet in Chronoswiss history. This architectural approach ensures a unified presence on the wrist, blending the iconic onion crown and coin-edge bezel with contemporary lines. Whether crafted from high-strength Grade 5 Titanium for daily wear or solid 18-carat 5N Gold, the 41mm case offers a powerful physical and visual statement.

At the heart of the collection beats the Manufacture Caliber C.6002, an automatic movement developed exclusively with La Joux-Perret. This dedicated mechanical construction provides a true dual-time display, featuring a 24-hour second time zone on the left and a 12-hour home time on the right, all unified by central minutes and seconds. With a 55-hour power reserve and water resistance up to 10 bar, the movement is designed for movement and mechanical clarity.

The collection showcases the height of Lucerne craftsmanship through two distinct dial interpretations. The Silver Guilloche edition celebrates pure mechanical texture with hand-guilloché patterns cut on century-old machines, while the Enamel Sky Gold features the rare art of paillonné enamel. This demanding craft embeds gold stars within layers of translucent fire enamel over a guilloché base, creating a celestial display designed to last for centuries.

A Deeper Cut: Armin Strom One Week Skeleton Rose Gold

   

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.
