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.

Armin Strom, the independent Swiss watchmaker renowned for its openworked designs and mechanical innovation, proudly unveils two striking new additions to its System 78 collection: the Orbit Lime Green and Orbit Ice Blue.

These limited edition timepieces—each restricted to just 20 pieces worldwide—introduce vibrant new fumé dials that blend bold aesthetics with technical mastery. The Lime Green model radiates energy and modernity, while the Ice Blue version offers a serene and sophisticated presence. Both dials feature a gradient effect that transitions from vivid color at the center to deep black at the edges, enhancing the visual depth of the openworked design.

A World-First Date Display on Demand

At the heart of both models lies the Armin Strom Manufacture Caliber ASS20, the world’s first movement to feature a date display on a ceramic bezel that appears only when activated. A pusher at 10 o’clock engages the date hand, which points to the current date and advances automatically at midnight. A second press returns the hand to its neutral position, offering a playful yet practical complication powered by a column-wheel mechanism.

The movement also incorporates Armin Strom’s patented Equal Force Barrel, delivering consistent energy for a stable 72-hour power reserve.

Haute Horology Craftsmanship

Each Orbit model is meticulously hand-finished at Armin Strom’s Manufacture in Biel/Bienne, employing traditional techniques such as anglage, perlage, and circular graining. The off-center dial is paired with rhodium-coated hands enhanced with Super-LumiNova®, ensuring legibility and elegance. The watches are housed in a stainless steel case with a fixed ceramic bezel and come with a matching bracelet featuring a double-folding clasp.

The Science of Movement

Founded in 1967 and revitalized in 2009, Armin Strom continues to push the boundaries of horological innovation. Every timepiece is designed, developed, and assembled in-house, reflecting the brand’s commitment to transparency, craftsmanship, and mechanical excellence.

gérald genta continues its legacy of audacious elegance with the launch of two new references in the Gentissima Oursin collection: Blue Meteorite and Green Meteorite. These timepieces mark a bold evolution of the iconic design first imagined by Mr. Gérald Genta in 1994, inspired by the delicate yet resilient form of the sea urchin.

A Design Born from Nature and the Cosmos
The Gentissima Oursin 41 features a 41mm sandblasted Grade 5 titanium case, meticulously set with 234 white gold beads, echoing the organic geometry of the sea urchin. At its heart lies a dial carved from a fragment of meteorite—a material born from the stars—making each watch a unique, one-of-one creation. The natural crystalline structure of meteorite ensures that no two dials are alike, offering collectors a truly rare expression of artistry.

Sporty-Chic Meets Haute Horlogerie
Combining rubber straps and titanium architecture with luxurious gold accents, the Gentissima Oursin 41 is designed for everyday wearability without compromising sophistication. A curved sapphire crystal, faceted with a subtle octagonal profile, protects the dial and enhances its dynamic character. Gold hands filled with Super-LumiNova featuring a pink hue—a tribute to Mr. Genta’s favorite color—ensure legibility and elegance.

Mechanical Excellence
Inside beats the Zenith Elite GG-005 automatic movement, boasting a 50-hour power reserve, 4 Hz frequency, and an 18K yellow gold oscillating mass, visible through a sapphire caseback. With 50m water resistance and a comfortable rubber strap, this timepiece is as practical as it is artistic.

Armin Strom unveils the One Week Manufacture Edition Blue, a bold evolution of its foundational calibre, now reimagined in a striking deep blue. Limited to just 100 pieces, this timepiece reflects the brand’s dedication to mechanical artistry and uncompromising craftsmanship.

A Sculptural Expression of Precision
Encased in a 41 mm stainless steel case and paired with an integrated steel bracelet, the watch features a fully openworked architecture. The traditional dial is replaced by a blue PVD-coated mainplate, creating a vivid stage for the movement’s choreography. Every component is arranged in perfect symmetry, emphasizing depth, contrast, and clarity.

Engineered for Endurance
At its core is the manual-winding Calibre ARM21, developed and assembled entirely in-house. With dual barrels in series, it delivers a full seven-day power reserve and operates at 3.5 Hz for enhanced stability. A standout feature is the three-dimensional power reserve indicator, driven by a conical gear and polished cone — a nod to traditional pocket watches.

Each movement is hand-finished to haute horlogerie standards, with Geneva stripes, polished bevels, and chamfered edges. Every piece is assembled twice, ensuring flawless performance and visual harmony.
