Lunar Chronograph Aurora

Arnold & Son has unveiled its new "Perpetual Moon 41.5 Steel Colours of the Moon" collection, a series of highly exclusive, limited-edition timepieces inspired by the changing celestial hues of Earth's natural satellite. Detailed in the official release document, "ENG_A&S PM 41.5 Steel Colours of the Moon.doc", the collection features three distinct versions—the Blue Moon, Golden Moon, and Red Moon—each celebrating a unique atmospheric or seasonal phenomenon that alters the Moon's appearance and has fascinated civilisations throughout history.

Reinterpreting the iconic Perpetual Moon collection, these new models introduce a 41.5 mm stainless-steel case that balances horological exclusivity with everyday versatility. In a watchmaking first, Arnold & Son has applied a pioneering Physical Vapour Deposition (PVD) treatment directly onto precious mother-of-pearl. This innovative process creates deep, shifting reflections across the dials and moon-phase skies, showcasing the natural organic layers of the material with patterns that recall the flowing grain of Damascus steel.

The astronomical precision of the moon phase is enhanced by Super-LumiNova hidden beneath the colored mother-of-pearl moon disc, accompanied by hand-painted luminescent constellations of Cassiopeia and Ursa Major—a poetic tribute to historical mariners who relied on them for navigation. Bringing this celestial mechanics to life is the in-house A&S1512 manual-winding calibre. This movement provides a generous 90-hour power reserve and displays meticulous luxury finishes, including radiating Côtes de Genève and a secondary moon-phase indicator, all visible through the sapphire crystal case back.

Each of the three references is paired with a matching hand-stitched alligator leather strap and secured with a stainless-steel pin buckle. To maintain their extreme exclusivity, production is strictly limited to just 18 pieces per version.

Chronoswiss is proud to unveil the Delphis Glacier, a sophisticated interpretation of eternal ice and glacial beauty. Crafted in lightweight titanium and paired with a sleek black rubber strap, this latest addition to the Delphis family merges understated elegance with the bold mechanical spirit of Chronoswiss. Frozen landscapes meet modern horology. The Delphis Glacier is housed in a 42mm Grade 5 titanium case, whose natural metallic finish reflects the quiet strength and purity of alpine glaciers. Combined with the black rubber strap, the watch achieves a refined and contemporary presence on the wrist, evoking the calm majesty of ice formations shaped over centuries by nature itself.

Mechanical Cool
At the heart of the Delphis Glacier lies an upper dial that creates the stage for the retrograde minute and jumping hour complication. The crescent is silver galvanic and features a curved hand-guillochéd surface inspired by the delicate textures of glacial ice and frozen landscapes. The subdial, a curved UFO, holds the small seconds and is finished with a blue CVD-coating with hand-guilloché craftsmanship executed inside the Atelier Lucerne. The monochromatic interplay of textures and tones creates a sophisticated composition that feels both timeless and unmistakably modern.

The Soul of Precision
The Delphis Glacier is powered by the manufacture movement C.6004, a testament to Chronoswiss dedication to precision and innovation. Beyond its visual elegance, the movement ensures outstanding functionality and reliability, transforming the Delphis Glacier into a mechanical sculpture inspired by the silent power of nature. Every detail reflects the serene beauty and resilience of Swiss glaciers. As an homage to the enduring beauty and the purity of ice, the Delphis Glacier is produced in a limited edition of only 50 pieces, making it a rare companion for collectors seeking refined modern mechanics. Discover the silence. Embrace the glacier.

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.

Haute Horlogerie Dominique Renaud (HHDR) marks its official debut with the launch of the Pulse60, unveiled in preview at the Time To Watches fair in Geneva (April 14–19, 2026). This first creation of the new Dominique Renaud brand introduces a radical approach to low‑frequency mechanical watchmaking and expresses the purest form of Renaud’s watchmaking philosophy.

A Vision Rooted in First Principles
Dominique Renaud, co‑founder of the legendary Renaud & Papi manufacture and creator of numerous landmark complications, returns with a renewed focus on foundational movement principles. Guided by the maxim “form ever follows function,” his work embraces clarity, purity and a minimalist, self‑evident aesthetic.
The establishment of HHDR in Tolochenaz brings together a team of watchmakers, designers and engineers in a collaborative, idea‑driven environment. HHDR is conceived as a living laboratory — a place where experimentation, shared expertise and long‑term exploration shape new forms of contemporary horology.

Pulse60 — A New Mechanical Language
At the heart of the Pulse60 is the newly developed BUA2024 movement, which embraces an ultra‑low 1 Hz frequency — just one oscillation per second, echoing the natural rhythm of the human heart. This approach reduces escapement shocks and disturbances, transforming time measurement into a slower, more embodied rhythm.

To master this low frequency, the movement features a monumental 20 mm high‑inertia balance wheel, inspired by marine chronometers. Its large moment of inertia stabilizes the rate by absorbing minute variations in energy and motion.

Dominique Renaud has also completely reimagined the regulating organ, allowing amplitude greater than 360° without knocking, with a theoretical range reaching approximately 700°. This unprecedented freedom greatly improves static rate stability by allowing the balance to follow its own natural dynamics over a longer portion of its oscillation.
 

A Design That Expresses Its Mechanics
The Pulse60’s innovative mechanics are reflected in its seamless, fluid architecture:

- A domed crystal with no bezel
- Lug‑less construction and integrated strap
- Three‑part case structure
- Diamond‑cut or guilloché dial details
- A patented offset regulation system placed outside the balance wheel, offering a completely unobstructed view of the slow‑beating 1 Hz oscillator

The display includes an hour‑minute dial at 12 o’clock, a natural dead half‑second at 9 o’clock, and a torque indicator at 3 o’clock. The caseback reveals a minimalist composition of circular and linear forms, framing the openworked escapement line and double‑roller assembly.
