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.

Moritz Grossmann GMT Guilloche Limited Edition Dual Time Zone Watch with Hand-Guilloché Dial

The Moritz Grossmann GMT Guilloche is a celebration of global exploration and fine German watchmaking. Inspired by the colors of nature and the rhythm of travel, this dual time zone watch is available in two striking dial variants: matte green, evoking serene meadows and hidden coves, and vibrant orange, reminiscent of the glow of a setting sun.

Dual Time Functionality

Designed for the modern traveler, the GMT Guilloche features a 24-hour time zone ring encircling the dial. A distinctive arrow-shaped hand tracks a second time zone, offering intuitive day-night orientation. Local time is displayed via central hour and minute hands, with a small seconds subdial at 6 o’clock. A dedicated crown at 10 o’clock allows seamless adjustment of the second time zone without affecting the main time.

Masterful Craftsmanship

Each dial is hand-engraved using the traditional guilloché technique, creating intricate geometric patterns that shimmer with light. The green dial is paired with blued steel hands, while the orange dial features polished steel hands—both handcrafted in Glashütte.

Engineered for Precision

Inside the watch beats the calibre 100.8, a manually wound movement crafted in-house and regulated in five positions. It features 253 components, 26 jewels, and signature Grossmann innovations including the 2/3 plate with raised gold chatons, cantilevered balance cock with micrometer screw, and a separately removable winding mechanism. The second time zone mechanism is seamlessly integrated on the dial side, ensuring precision and harmony.

Limited Edition

Encased in stainless steel and fitted with a hand-stitched black alligator leather strap, each GMT Guilloche model is strictly limited to 8 pieces worldwide, making it a rare collector’s item.

Discover the Art of Glashütte

Moritz Grossmann continues to honor its founder’s legacy by blending traditional craftsmanship with modern innovation. The GMT Guilloche is a wearable work of art—an invitation to wear the world on your wrist.

Armin Strom Introduces The One Week Skeleton

The Armin Strom One Week Titanium Skeleton, an openworked masterpiece now fully skeletonized to reveal the intricate heart of its mechanics, combines striking design with precision engineering. Encased in lightweight titanium grade 5, it balances strength with comfort, providing a feeling of lightness that makes it easy to wear all week long.

The Armin Strom One Week Titanium Skeleton is a showcase of skeletonization, a technique that is rooted in Mr. Armin Strom’s philosophy and heritage. He sought to enhance depth and three-dimensionality while avoiding see-through to maintain elegance.

The 2023 One Week was already openworked by nature, but this version goes even further, removing more material to highlight the movement’s complexity. Few watches combine openworking and skeletonization at this level. The small seconds dial is skeletonized, revealing the power reserve level and the escapement wheel for a 3D mechanical animation. The mainplate and the barrels are also skeletonized enhancing aesthetics. Thanks to this skeletonization, the power reserve indicator is highlighted as well as the cone mechanism, reminiscent of ancient pocket watches. A major highlight is the case back, offering a mesmerizing view of the entire mechanism.

With a 7-day power reserve, this watch keeps time accurate for an entire week without needing winding. The hand-finished details reflect the level of craftsmanship behind its design. Limited to 100 pieces, the One Week Titanium Skeleton offers a refined, functional timepiece that blends robustness and comfort in a minimalist package.

Back in sleek anthracite: Armin Strom unveils the One Week Manufacture Edition

Biel/Bienne, Switzerland, 26 June 2024: Following the inaugural redesigned One Week First Edition that made its debut in 2023, Armin Strom unveils a new version of the successor to its first-ever manufacture movement with the One Week Manufacture Edition. The highly architectural openworked movement, housed in a sleek and sporty steel case with an integrated bracelet, is now presented in a range of grey and anthracite hues. Limited to 100 pieces, the One Week Manufacture Edition foregoes colour to bring out the beauty of its uniquely constructed manual calibre.

15 years ago, independent watchmaking brand Armin Strom took a major leap that would forever change its trajectory. Realising that the path to true independence lies in mastering every step of the process, it established its very own manufacture in Biel. A year later, the first timepiece produced by its vertically integrated manufacture was unveiled: the One Week. Entirely developed and manufactured in-house and designed with symmetrical harmony in mind, it stood out thanks to its unique movement architecture featuring two barrels that together provide a seven-day power reserve. This milestone marked the beginning of many new calibres and innovations by the Armin Strom manufacture, showcasing their dedication to the science of movement and garnering the admiration and respect of even the most discerning and seasoned collectors.

The new One Week Manufacture Edition completely reimagines this milestone calibre in line with the brand’s recent bolder, more three-dimensional approach to calibre design, all in a sleek and serene execution that further highlights its ingenuity and uniqueness. The mainplate, bridges and parts, visible on the dial thanks to the openworked movement design, are anthracite PVD coated for a striking look.

As Armin Strom founder Serge Michel notes: “Collectors who missed the opportunity to get a first edition of the redesigned One Week will now have another chance. The Manufacture Edition of the new One Week will be limited to 100 pieces.”

Sporty yet classy, this model exudes calmness and serenity with its anthracite tones and the symmetrical harmony of its in-house movement.

Traditional craftsmanship with modern appeal - Moritz Grossmann TREMBLAGE Green

Moritz Grossmann proudly unveils the TREMBLAGE Green, a limited edition timepiece that redefines elegance through heritage craftsmanship and a bold new aesthetic. Available in rose gold and white gold, with only 8 pieces of each, this extraordinary watch is a tribute to the art of traditional engraving and the timeless beauty of horological design.

At the heart of the TREMBLAGE Green lies a dial crafted from German silver, meticulously hand-engraved using the rare tremblage technique. This centuries-old method creates a fine, matte texture that diffuses light with a soft, meditative glow. The dial is finished in a deep, complex green—symbolizing renewal, harmony, and depth—making it a standout piece that remains understated and refined.

Encased in a 41 mm case of 750/000 rose or white gold, the watch is powered by the in-house calibre 100.1, a hand-wound movement visible through a sapphire crystal case back. Every component is hand-finished, from the Glashütte ribbing and polished bevels to the engraved balance cock. The watch features hours, minutes, and a small seconds display with a stop-second function, all operated via a gold crown and lateral pusher.

Completing the look is a hand-stitched dark brown alligator leather strap, offering both comfort and sophistication. The TREMBLAGE Green is not just a timepiece—it is a celebration of “Schönstes deutsches Handwerk” (the finest German craftsmanship), brought to life with modern sensibility and timeless appeal.
