Chromatic Precision: Armin Strom Orbit in Lime & Ice

JULY 18 2025    |    Novelties

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.

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.

Technical Excellence: A&S5201 Calibre

Dual barrels provide an impressive 90-hour power reserve.

Components are arranged in a kinematic chain around the edge, enhancing both function and form.

The crown mechanism is inverted and placed on the case-back side for symmetry with the first wheel at 9 o’clock.

Aesthetic Details

The lower levels of the movement are treated with a rich blue PVD, contrasted by palladium-finished bridges and components.

Includes horizontal satin brushing on the dial side and Arnold & Son’s signature ‘Rayons de la Gloire’ motif on the reverse.

The 40 mm diameter and 9.10 mm thickness ensure elegance on the wrist.

Strap & Bracelet Options
