Angelus unites the chronograph's key functional scales—telemeter, pulsometer, and tachymeter—in a single design. True to its heritage as a maker of functional timepieces, Angelus brings together the expertise developed through its previous instruments in the Instrument de Mesures. Produced in two limited editions of 25 pieces, this watch is a genuine instrument of measurement, designed to calculate elapsed time, the speed of sound, distance travelled and heart rate. Using a single chronograph hand, it integrates three functions, each with its own dedicated scale. Housed in a 39 mm steel case, its three-dimensional dial is both highly legible and meticulously graduated, giving the Instrument de Mesures the character of an authentic tool watch with a distinctive vintage charm and singular identity.

One Instrument, Multiple Measurements
Integrating these three scales alongside the essential minute track required a particularly sophisticated design approach. The amount of information to be displayed, combined with the need for legibility and clarity, led Angelus to adopt a distinct colour code for each function. This arrangement is reinforced by a three-dimensional dial construction, featuring a domed centre and outer edge connected by a sloping intermediate section. The telemetric scale is situated on the highest level at the periphery of the dial. The pulsometer extends across the angled intermediate section, and the tachymeter, in the form of a spiral, is located closest to the hands.

The In-House A5000 Chronograph Calibre
The Instrument de Mesures is powered by Angelus's in-house A5000 chronograph calibre. Its classical architecture showcases numerous intricately shaped components, providing an ideal canvas for high-end finishing. Faithful to the great traditions of chronograph watchmaking, the A5000 incorporates a column wheel and a horizontal clutch, both defining features of traditional chronographs.

Armin Strom proudly presents the Mirrored Force Resonance Ice Blue, a limited edition timepiece that exemplifies the brand’s dedication to horological innovation and artisanal excellence. With only 15 pieces available worldwide, this release marks a bold evolution in the art of synchronized timekeeping.

The watch features a striking ice blue sunray guilloché dial, crafted using a traditional hand-operated rose engine lathe. Its off-center layout and radiant finish create a captivating play of light beneath the sapphire crystal, while beveled and polished indexes and hands add depth and movement to the design.

At the core of this timepiece is the manually wound Caliber ARF21, a technical breakthrough in resonance watchmaking. Armin Strom’s patented clutch system connects two balance wheels, allowing them to oscillate in opposite directions and synchronize for enhanced precision and stability. Twin seconds counters provide a visual representation of this resonance effect, and a pusher at 2 o’clock resets the counters, offering a clear demonstration of the mechanism’s accuracy.

The movement is hand-finished to haute horology standards, with Geneva stripes, perlage, and black-polished screws visible through the transparent case back. Each watch is assembled twice to ensure both mechanical integrity and flawless finishing.

Encased in a 43 mm stainless steel case and paired with a dark blue Alcantara strap, the Mirrored Force Resonance Ice Blue is a celebration of independent Swiss watchmaking and the science of movement.

Known for bold evolutions of mechanical wristwatches and daring designs, Chronoswiss unveils its latest creature: the ReSec Snake. Slithering between heritage and rebellion, this timepiece is a hypnotic blend of color, contrast, and kinetic energy — proof that modern mechanical watchmaking still has a few fangs to bear.

The Snake’s Bite

The ReSec Snake coils into view within a 42mm titanium case, coated with a mesmerizing color-changing PVD-coating that shifts from emerald green to turquoise, depending on the light. It’s not just a case — it’s iridescent armor, capturing the reptilian allure of a serpent in motion. Paired with a contrasting white rubber strap, the Snake wraps around the wrist with smooth, tactile elegance.

But the true venom lies beneath the sapphire crystal. A green CVD-coated dial, hand-guillochéd in the Lucerne Atelier, pulses with depth and hypnotic texture. It’s a dial that doesn’t just tell time — it seduces it.

Take a closer look, and the architecture reveals itself: the iconic 3D regulator layout of the ReSec series slithers across the dial, framed by green hour and minute rings and a retrograde second display, like the flick of a serpent’s tongue. Underneath, the exposed gear train glimmers in contrasting tones — a mechanical exoskeleton that moves with silent precision.

Fangs Beneath the Surface

Powering this cold-blooded beauty is the Chronoswiss Manufacture Caliber C.6005, featuring a 55-hour power reserve, ruthenium-plated finishing, and a radial Côtes de Genève motif. It’s mechanical watchmaking at its sharpest: sleek, silent, and engineered to strike.

Limited. Lethal.

Only 100 pieces of the ReSec Snake will ever exist — a rare breed for collectors with a taste for the untamed. The ReSec Snake is a statement: of daring, of detail, and of defiance — proving once again that at Chronoswiss, we don’t follow rules. We shed them.

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

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.
