Armin Strom Unveils the Gravity Equal Force Ultimate Sapphire Rose Gold — A Masterpiece of Mechanics and Elegance

JUNE 18 2025 | Novelties

Independent Swiss watchmaker Armin Strom proudly presents the Gravity Equal Force Ultimate Sapphire Rose Gold, a timepiece that exemplifies the brand’s commitment to horological innovation, artisanal craftsmanship, and visual harmony.

Encased in 18K rose gold, this limited-edition watch features a sculptural movement architecture that plays with tone and texture. A brown guilloché mainplate, rose gold-colored bridges, and a floating off-centre sapphire dial create a refined and coherent composition. The watch is paired with a matte brown nubuck leather strap, adding an earthy elegance to the overall aesthetic.

At the heart of the timepiece is the Caliber ASB19, Armin Strom’s groundbreaking automatic movement. It incorporates a patented stop-work declutch mechanism and Geneva cross within the barrel, ensuring consistent torque delivery throughout its 72-hour power reserve. A micro-rotor enables efficient winding while preserving the symmetry and visibility of the movement — a hallmark of Armin Strom’s design philosophy.

Every component, visible or hidden, is hand-finished to haute horology standards. Techniques such as beveling, straight-graining, perlage, Geneva stripes, and black-polished screws are applied with precision and care. The mainplate features a “grain d’orge” guilloché pattern, crafted by master artisan Kari Voutilainen using a traditional hand-operated machine.

This exceptional timepiece is limited to just 25 pieces per year, making it a rare and radiant statement in the world of independent watchmaking. It is a testament to Armin Strom’s philosophy: Mechanics First. Always.

Armin Strom Unveils the Dual Time GMT Resonance Rose Gold

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

Introduction of assertive new black dials for the C by Romain Gauthier Titanium Edition Bracelet

Released initially with a grey dial and then with a Lever de Soleil color dial, the C by Romain Gauthier Titanium Edition Bracelet is now featured with two new dials: a three-dimensional straight grained structured dial in Grade 5 black titanium with white details and a black sapphire openwork dial with blue and white accents.

The three-dimensional straight grained black titanium dial provides an even more assertive character with its textured surfaces. The sharp contrast between the white details and the dark background enhances the time indications. This dial embodies a distinctly modern design while maintaining excellent readability, even in low-light conditions, thanks to the use of Super- LumiNova on the indexes, numerals, and hands.

As for the sapphire openwork dial, it reveals the intricate components of the movement, showcasing the brand's sophisticated watchmaking engineering and artisanal craftsmanship. This openwork design creates a captivating interplay between transparency and structure, transforming the watch into a true technical and aesthetic masterpiece. When Romain launched the first edition of C by Romain Gauthier in 2021, it was clearly stated that this new caliber would lead the brand to new horizons. One year later, a new door has been opened with the arrival of the brand's first metal bracelet.

Sober and contemporary, propitious to variations and adaptations, C by Romain Gauthier was an obvious choice for the creation of a metal bracelet. The desire of modernity, comfort and ergonomic already initiated during the conception of the first edition, reinforced the development of this integral timepiece on a titanium bracelet - light, resistant, modern and sophisticated. Aesthetically, it was important to Romain that the bracelet and the watch become one. As he said: "The bracelet is the case, and the case is the bracelet". This desire is reflected in the fusion of these two elements, a timepiece as a whole that cannot be dissociated.

In keeping with Romain's vision - The Evolution of Tradition - this new technical and contemporary element requires a high level of craftsmanship and hand finishing. Each link is composed of hand-polished and satin-finished surfaces that play with the light and reflect the technical nature of the bracelet and the piece in general.

Longitude Titanium - High-sea watchmaking

Arnold & Son, a benchmark in classic fine watchmaking, is exploring uncharted territory on the map of horology. Longitude Titanium is a sports-chic COSC-certified chronometer with a 42.5 mm titanium case. The dial of Longitude Titanium is vertical satin-finished in a continuation of the bracelet’s finish, which is subtly intersected by the polished edges of its links. With a power-reserve display at 12 o’clock and an imposing seconds counter at 6 o’clock, Longitude Titanium pays tribute to John Arnold’s marine chronometers, his revolutionary vision and his decisive role in calculating longitude at sea.
The aesthetics and construction of John Arnold’s marine chronometers were necessarily classic and functional, and were adapted to the harsh conditions of the high seas. Longitude Titanium, a contemporary interpretation of the great English watchmaker’s work, coherently combines this naval heritage with a refined design and highly resistant materials. The movement’s ‘chronometer’ certification is an essential addition to this scene, with its historical ties to Arnold’s creations and his quest for accuracy.

Operating at 3.5 Hz, the calibre ensures consistent precision and stability in daily wear.

Inspired by historical pocket watches, the conical power reserve mechanism is complemented by a 3D power reserve indicator, displaying remaining energy with exceptional clarity. Central hours and minutes keep the display symmetrical, while a skeletonised small seconds at 9 o’clock adds an engaging sense of motion.

Transparency in Gold
Every component of the Calibre ARM21-S is decorated by hand, reflecting Armin Strom’s dedication to traditional craftsmanship. Hand-polished bevels, Geneva stripes, circular graining, and finely finished screw sinks demonstrate uncompromising attention to detail.
