PULSE GMT Frosted Guilloche Gold

We are thrilled to announce the launch of the Armin Strom Gravity Equal Force Ultimate Sapphire Blue, a masterpiece of Swiss horology that combines technical innovation with glacial elegance.

Design & Aesthetics

The watch features a 41 mm stainless steel case and an off-center transparent sapphire crystal dial with a subdial. The main plate, crafted by Kari Voutilainen, showcases a stunning glacial blue guilloché pattern. The color palette of silvery greys and soft blues is inspired by the serene beauty of Swiss glacial lakes. The watch is completed with a blue nubuck leather strap with ice blue stitching.

Movement & Mechanics

Powered by the proprietary Caliber ASB19, the Gravity Equal Force Ultimate Sapphire Blue is the world’s first automatic movement with a patented stop-work declutch mechanism and Geneva cross. This ensures consistent torque and precision across a 72-hour power reserve. The movement is visible through both the front and back sapphire crystals, and features hand-finished components with perlage, Geneva stripes, and circular graining.

Craftsmanship

Each watch is assembled twice to ensure reliability and refinement. Every component is hand-finished in Biel/Bienne, emphasizing traditional techniques and an open-worked design.

Brand Philosophy

Armin Strom celebrates Swiss horological tradition and innovation. Founded in 1967 and revitalized in 2009 by Claude Greisler and Serge Michel, the brand is known for exposing movement mechanics on the dial side. Their motto, “The Science of Movement,” reflects their dedication to precision and craftsmanship.

Limited Edition

The Gravity Equal Force Ultimate Sapphire Blue is limited to just 25 pieces per year, making it a truly exclusive timepiece.

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.

Independent manufacture Romain Gauthier illuminates its modern horological vision with the unveiling of the C by Romain Gauthier Titanium Edition Bracelet Lumen dial (Ref. MON00585). For the very first time, the brand integrates a full Super-Luminova dial into its celebrated Freedom collection, using light itself as a core design material. Deliberately paired with the C by Romain Gauthier Titanium Edition Bracelet—available for the first time in a limited edition of just 28 pieces—this creation redefines nocturnal legibility with ergonomic, everyday titanium luxury.

By day, the timepiece displays a refined, crisp white aesthetic anchored by sharp Grade 5 titanium numerals, indices, and hands. When darkness falls, the entire watch face transforms into a brilliant blue glow, creating a striking contrast that ensures effortless readability in any lighting condition. The integrated Grade 5 titanium bracelet—meticulously finished with alternating satin-brushed and hand-polished facets—flows seamlessly from the 41mm x 9.55mm case (47.8mm lug-to-lug), providing lightweight comfort and an uninterrupted, architectural silhouette.

Beneath the luminous dial lies an uncompromising expression of high-end Swiss watchmaking. Visible through the sapphire display back, the in-house hand-wound calibre crafted in natural Grade 5 titanium showcases Romain Gauthier’s heritage from the Vallée de Joux through modern "stepped" finger bridges. Each bridge is meticulously decorated with an exclusive hand-engraved dimpled texture, standing out against a hand-frosted movement mainplate while delivering a robust 60-hour power reserve.

Technical precision remains central to the manufacture's DNA, highlighted by the inclusion of a clever stop-seconds mechanism driven by a snail cam—a signature innovation inspired by the acclaimed Logical One. Pulling the off-center crown halts the balance wheel, while pushing it back in triggers the snail cam to deliver a subtle physical impulse, ensuring the movement restarts instantly. Strictly limited to 28 pieces worldwide, the C by Romain Gauthier Titanium Edition Bracelet Lumen dial represents an extraordinary convergence of glowing nighttime drama and superlative independent watchmaking.

Chronoswiss expands its avant‑garde Space Timer collection with the new SPACE TIMER GRAVITY, a 44mm mechanical creation inspired by the invisible yet powerful force of gravity. Limited to 50 pieces, the watch transforms cosmic phenomena into a visually architectural dial experience.

A Dial Where Light, Matter, and Mechanics Interact
The dial features a partly hand‑guilloché surface finished with a colour‑shifting CVD coating that transitions between deep green and oceanic blue depending on light — evoking the sensation of viewing a planet from orbit. A striking moon at 9 o’clock is produced through sophisticated laser work based on an original NASA photograph, revealing cratered textures with exceptional depth.

Floating above the landscape are transparent ITR2 hour and date rings that appear suspended in orbit. Beneath them, the exposed gear train is framed by a baby‑blue bridge, echoing the hue of the seconds hand and adding contemporary contrast to the cosmic scene.

A Case Built for Orbit
The 44mm matte‑grey stainless‑steel case delivers a modern, technical presence while allowing the dial’s dynamic surfaces to take centre stage. It pairs with a light grey nubuck leather strap for a refined, futuristic aesthetic.

The Engine Behind the Cosmos
Inside beats the Chronoswiss Caliber C.308, an automatic movement operating at 4 Hz with a 42‑hour power reserve. Mechanics remain proudly visible, emphasising the interplay between the unseen forces of gravity and the precise regulation of time.

A Limited Universe
Limited to 50 pieces worldwide, each SPACE TIMER GRAVITY captures the dance of light across its shifting dial, making every piece uniquely personal.
