Armin Strom Orbit Lime Green & Ice Blue

In the world of independent watchmaking, few designs capture the essence of mechanical artistry and thematic storytelling like the Chronoswiss Strike Two collection. With its signature horizontal regulator layout and exposed gear architecture, the collection is a canvas for both cosmic inspiration and historical homage. The Stellar Blue and Nugget editions, though forged from different visions, share a unified spirit: precision in motion, elevated by craftsmanship.

Architecture of Time

At the heart of both models lies the Chronoswiss Manufacture Caliber C.6000, developed in collaboration with La Joux-Perret. This automatic movement delivers a robust 55-hour power reserve, beating at 4 Hz (28,800 A/h). A skeletonized tungsten rotor, ruthenium-plated Geneva-cut bridges, and polished components reflect the brand’s commitment to mechanical transparency and refinement. Viewed through a sapphire caseback, the movement reveals a radial geometry that echoes the symmetry of the dial above.

The horizontal regulator layout defines the Strike Two identity: a floating hour display at 3 o’clock, central luminous minutes, and a small seconds subdial at 9 o’clock. Two architectural bridges span the dial, exposing the gear train and anchoring the visual rhythm of the watch.

Stellar Blue – A Tribute to Cosmic Velocity

The Stellar Blue edition draws inspiration from the brilliance and motion of stellar light. Its dial features a deep blue CVD-coated base, hand-guillochéd with linear engraving that mimics the trajectory of light through space. A silver rhodium-plated subdial adds contrast, while the luminous minute hand glides across the dial like a comet in orbit.

Encased in matte grey sandblasted stainless steel, the watch offers a futuristic silhouette that complements its celestial theme. Measuring 40 mm in diameter and 12.7 mm in thickness, it wears with elegance and presence. The strap is crafted from white nubuck calfskin leather, lined with blue Alcantara, echoing the dial’s cosmic hue.

Nugget – A Homage to Discovery and Rarity

In contrast, the Strike Two Nugget is a celebration of terrestrial treasure — a mechanical gold rush forged in solid 18ct red gold. Inspired by the thrill of unearthing something precious, the Nugget edition elevates the Strike Two architecture with warmth, weight, and richness.

Its anthracite dial, hand-guillochéd and treated with a galvanic finish, reveals depth and texture. A glossy white lacquered small seconds subdial punctuates the monochrome palette, while the exposed gearwork beneath the hour display adds mechanical drama.

The case, polished and sandblasted, retains the 40 mm diameter and 12.7 mm thickness, but its golden sheen transforms the watch into a statement of rarity. Paired with a black nubuck calfskin strap lined in blue Alcantara, the Nugget balances boldness with refinement..

Two Visions, One Philosophy

Whether inspired by the stars or the soil, the Strike Two Stellar Blue and Strike Two Nugget embody Chronoswiss’s philosophy of independent design, mechanical excellence, and thematic storytelling. Limited to 100 pieces each, these timepieces are not just instruments of time — they are expressions of discovery, crafted for collectors who seek meaning in every detail.

Greubel Forsey introduces the final and most exclusive editions of the Balancier Convexe S²: one in black ceramic with 5N red gold, and one in white ceramic, each strictly limited to 11 pieces.
These editions conclude a calibre developed through five years of mechanical and architectural exploration, with production set to cease permanently in 2026.

The Convexe case (41.5 mm) and movement were conceived as a single architectural whole, integrating Greubel Forsey’s signature 30° inclined balance wheel system as the visual and chronometric centre. The openworked movement features 301 components, including a 68‑part escapement platform, and is powered by two rapid-rotation coaxial barrels delivering a 72‑hour chronometric reserve.

Finishing remains uncompromising: frosted titanium bridges, polished bevels, hand‑finished countersinks, and meticulous transitions — even on invisible components.

Two Final Interpretations
Black Ceramic & 5N Red Gold
A dramatic contrast of dark architecture framed by ceramic, with red gold adding warmth and sculptural depth.The interplay of matte and polished surfaces enhances the piece’s three‑dimensional form

White Ceramic
A purist, graphic expression that highlights the structural geometry of the movement through light and shadow.The monochromatic case offers clarity, openness and a distinctly technical aesthetic.

Both editions preserve the characteristic S² display: suspended hours/minutes bridge, small seconds, and sector power‑reserve indication beneath a curved sapphire crystal.

This launch marks the concluding chapter of the Balancier Convexe S²’s five‑year evolution — not an iteration, but a final statement. As of 2026, Greubel Forsey will begin a gradual shift toward an almost entirely new collection, retiring earlier calibres with intention and ceremony rather than quiet discontinuation.

Armin Strom presents a refined and visually striking evolution of its celebrated Dual Time GMT Resonance collection with the debut of the Dual Time GMT Resonance Rose Gold. Rendered for the first time in a 39 mm 18K rose‑gold case, the timepiece introduces a warm and elegant reinterpretation of the brand’s technically driven design language. Limited to 50 pieces worldwide, this edition pairs the Maison’s signature resonance innovation with a rich new aesthetic personality, blending contemporary elegance with mechanical sophistication.

A New Expression of Design & Craftsmanship
The new Rose Gold edition distinguishes itself through its interplay of warm tones and finely executed textures. The 18K rose‑gold case forms a glowing frame around the black‑gold grenage dial, a surface enriched by depth, contrast, and granular refinement. The dial’s twin layouts—each dedicated to one time zone—are clearly defined by black azurage chapter rings, ensuring intuitive reading while maintaining the balanced symmetry that defines the Resonance line. The rose‑gold‑coloured, faceted and polished hands, together with matching applied indexes, elevate the aesthetic with a luxurious brightness. At six o’clock on each sub‑dial, polished and blackened steel sun-and-moon day/night discs add functional clarity and a poetic visual touch. Completing the ensemble is a matte anthracite alligator strap accented with grey stitching and secured with a matching 18K rose‑gold pin buckle, creating a cohesive, modern, and refined profile.

The Science of Movement: Calibre ARF22
At the heart of the watch lies Armin Strom’s hand‑wound, in‑house Calibre ARF22, a movement defined by the brand’s patented resonance clutch system. This mechanism couples two independent balance wheels and allows them to synchronise through resonance, a natural physical phenomenon that enhances chronometric stability. What might otherwise remain a theoretical curiosity is transformed into a practical complication: each regulating organ governs its own time display, enabling two entirely independent time zones. Each dial also features a corresponding day/night indicator, making the watch particularly intuitive for world travellers. Operating at 3.5 Hz (25,200 vph) and offering a 42‑hour power reserve, the ARF22 movement brings a dynamic, kinetic quality to the dial, where the twin oscillators interact in real time. The aesthetic presentation of the movement reflects haute horlogerie values, with meticulous hand‑polished bevels, black‑polished steel components, circular graining, perlage, and Côtes de Genève on full display through sapphire crystals on both sides. In keeping with Armin Strom tradition, each watch is assembled twice, ensuring uncompromising mechanical integrity and flawless finishing.

The new Dual Time GMT Resonance Rose Gold is offered in a strictly limited edition of 50 pieces
