Introducing the Armin Strom Gravity Equal Force Ultimate Sapphire Blue

JUNE 25 2025    |    Novelties

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.

Angelus Unveils Flying Tourbillon Skeleton Titanium in Vivid Orange

Angelus unveils the Flying Tourbillon Skeleton Titanium, Orange Edition, a vivid expression of horological energy and design. Limited to just 25 pieces, this timepiece transforms skeletonised mechanics into a canvas of colour and contrast. The satin-finished titanium case frames a deep black movement, animated by bright orange accents that highlight the time display and extend to three interchangeable straps. The openwork calibre, designed as a series of interlocking circles, adds architectural depth and visual dynamism.

Every detail of this 42.5 mm watch reflects a unique energy. Chromatic energy flows through the orange highlights. Customisable energy is offered by the quick-release strap system, allowing seamless transitions between black alligator leather, orange rubber, and integrated titanium. Light energy emerges from the skeletonised movement, while structural energy is revealed in the layered construction. Graphic energy is embodied in the three-dimensional architecture of the A-310 calibre.

The dial features a floating orange minute track above a black flange, with hour markers crafted for the first time by Angelus in monolithic blocks of Super-LumiNova. These luminous elements ensure legibility in low light and reinforce the watch’s modern aesthetic. At the heart of the case lies a carbon composite chamber, lightweight yet rigid, surrounded by a modular titanium cage that enhances stability and mechanical appeal.

The A-310 calibre showcases Angelus’s signature three-spoke wheels, leading the eye to the flying tourbillon suspended without an upper bridge. Supported by a 160° angled bridge, this asymmetrical design intensifies visual tension and balance. The tourbillon completes a rotation every minute, oscillates at 4 Hz, and offers a 60-hour power reserve. The Flying Tourbillon Skeleton Titanium, Orange Edition embodies the Angelus L.A.B. philosophy—Legacy and Beyond—where technical mastery meets bold design to elevate mechanics into contemporary art.

Chronoswiss Unveils the SPACE TIMER GRAVITY — A New Exploration of Mechanical Cosmos

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.

Greubel Forsey Unveils Final Editions of the Balancier Convexe S² in White and Black Ceramic

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.

Neo Digiteur: Chronoswiss Revives the Mechanical Digital Icon

Chronoswiss proudly unveils the Neo Digiteur, a bold reinvention of an icon that first challenged convention two decades ago. Originally introduced in 2005 by founder Gerd-Rüdiger Lang, the Digiteur was a mechanical digital timepiece—a watch without hands—that defied expectations and celebrated horological artistry. Today, the Neo Digiteur returns sharper, stronger, and more modern than ever, crafted in stainless steel and infused with the pioneering spirit of its predecessor.

The design is architectural and tailored, with a rectangular case measuring 48 by 30 millimeters. Its sculptural lines are accentuated by sandblasted and polished finishes, while a reimagined onion-style crown ensures both elegance and ergonomics. At its heart lies a rare complication: a jumping hour regulator without hands. Time is displayed through three apertures—the jumping hour at twelve o’clock, digital minutes at center, and running seconds at six o’clock—creating a mechanical digital regulator that feels futuristic yet deeply analog.

Powering this display is the hand-wound Chronoswiss Caliber C.85757, beating at 3 Hz and offering a 48-hour power reserve. Developed entirely in-house, the movement features artisanal details such as hand-guilloché bridges and a sapphire crystal caseback that pays tribute to historic Fleurier calibers. Two limited editions express distinct personalities: Neo Digiteur Granit with an anthracite dial and Neo Digiteur Sand with a warm 4N sandblasted finish. Each version is limited to just 99 pieces, making the Neo Digiteur not a reproduction, but a true reinvention—a collector’s piece and a statement of mechanical artistry.
