Perpetual Moon 38 Night Tide - Diamonds making waves

JUNE 13 2024    |    Novelties

Waxing, gibbous, blue: the power of the moon imposes itself on the Earth and even more so, on the seas. Perpetual Moon 38 Night Tide celebrates the fluctuating pull of this celestial body on the water. A large moon disc appears over vast waves. Made of mother-of-pearl and ruthenium, they rise one after the other in a cascade of soft curves. This scene, illuminated by diamonds, celebrates the femininity, elegance and evocative power of Arnold & Son’s watchmaking.

Powerful and plentiful, the waves of Perpetual Moon 38 Night Tide herald heavy seas. In the blue of the night, the tide is at its highest, and so are the rollers. The moon, capricious and triumphant, imposes its will. The gradations of the water are topped with a sparkling foam. Beneath the peaceful light of Selene, the ocean rages on.

Arnold & Son interprets this powerfully symbolic scene through mechanisms and minerals. The astronomical moon complication of Perpetual Moon 38 Night Tide is adorned in mother-of-pearl and ruthenium: a delicate, evocative composition that fully expresses the dial-makers’ expertise. The mother-of-pearl marquetry, ruthenium crystal inlays and abundance of diamonds symbolise the painstaking care lavished on the women's collections of Switzerland’s most English brand.

 

Azure, navy, ink, midnight
Perpetual Moon 38 Night Tide is sculpted from a block of white gold. Once shaped, the 38 mm diameter and 10.44 mm thick case is adorned with 80 high-clarity diamonds. Together with the brilliant-cut diamonds adorning the buckle and the marquise-cut stones on the dial, they give a total weight of 2.62 carats. This gem-setting announces the ornamental richness with which Arnold & Son has composed this women’s complication.

Wave after wave, trough after trough, shades of blue and grey follow one another, creating a jumble of undulating seas, mother-of-pearl and ruthenium. Above this scene, a starry sky, punctuated by luminescent hand-painted constellations, is filled with an immense moon. Its surface, also made of ruthenium crystals, lights up the sky. This exceptional material has become a signature of Arnold & Son, adding preciousness, light and texture to its creations.

The grande dame of mechanisms
This limited edition of 18 pieces brings the watchmaking excellence of Arnold & Son to women. The Swiss brand has dedicated the smallest movement in its collection to Perpetual Moon 38.

At 29.4 mm, the A&S1612 calibre has been sized to fit the case. The hand-wound movement continues the house's tradition of calibres with long power reserves, reaching 90 hours.

Her Majesty the Moon
The star complication of the A&S1612 calibre is its moon phase. True to Arnold & Son's astronomical principle, Perpetual Moon 38 Night Tide features a moon disc almost as large as the calibre itself. The successive shapes of its crescent occupy the large aperture between 10 and 2 o'clock, while the form of its cut-out faithfully recreates the appearance of the moon.

In keeping with its tradition, Arnold & Son has given this moon phase an accuracy of 122 years. Continuously rising, it will take more than a century for this moon to lag one day behind the real one in our skies, watching over the oceans.

Celebrating 200 Years of Moritz Grossmann with the TREMBLAGE Gold

The year 2026 marks a momentous milestone for Moritz Grossmann as we celebrate the 200th anniversary of our founder’s birth. Moritz Grossmann was not only a master horologist but a visionary scientist and author who forever changed the landscape of Glashütte watchmaking. To commemorate his bicentenary, we are proud to unveil the TREMBLAGE Gold anniversary edition, a tribute that bridges his 19th-century spirit with the pinnacle of modern artisanal watchmaking.

This exceptional release introduces two limited editions, crafted in 750/000 rose gold and 950 platinum, with each variant strictly limited to just eight pieces worldwide. The soul of these timepieces lies in the solid rose gold dial, which has been meticulously hand-engraved using the rare "tremblage" technique. This traditional method involves a master engraver using a specialized burin to create a multi-directional, finely textured matte surface, resulting in a mesmerizing play of light that serves as a backdrop for the raised, hand-polished numerals.

The movement powering these anniversary models is the exquisitely finished Calibre 100.1 manual-winding movement. In a direct nod to the founder's legacy, the balance cock features a unique hand-engraved "1826," marking the year of Grossmann’s birth. Every component, from the heat-annealed brown-violet screws to the hand-carved pillars and German silver plates, reflects our commitment to "Schönstes deutsches Handwerk"—the finest German craftsmanship.

With the TREMBLAGE Gold edition, we do not simply replicate history; we evolve it. These watches embody the same pursuit of technological perfection and aesthetic brilliance that Moritz Grossmann championed two centuries ago. We invite you to discover these masterpieces, which stand as a testament to a heritage that continues to inspire every movement we create and every hand-finished detail we produce in our Glashütte manufactory.

Reinventing the Rhythm of Time: Dominique Renaud Presents the Pulse60

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.

Introducing the Armin Strom Mirrored Force Resonance Ruby

ARMIN STROM introduces a compelling new interpretation of its most emblematic complication with the debut of the Mirrored Force Resonance Ruby. This creation stands out through its extraordinary natural ruby dial, sourced and crafted by a local Swiss stone artisan. The brand selected only genuine ruby exhibiting depth of colour, fine inclusions, and naturally occurring variations—features that are not flaws but signatures of authenticity, shaped by geological processes over millions of years. As light moves across the dial, subtle tonal shifts appear, infusing the watch with a vibrant mineral presence that contrasts strikingly with the symmetry and modernity of the exposed mechanics.

Beyond its visual impact, this edition embodies ARMIN STROM’s belief that materials must carry meaning. While natural ruby asserts its aesthetic and symbolic presence on the dial, synthetic ruby jewels within the movement fulfil their longstanding horological role of reducing friction and ensuring long-term precision. It is a thoughtful dialogue between nature and engineering, where raw mineral beauty coexists with technical necessity.

At the core of the watch lies the hand-finished Calibre ARF21, a manufacture movement entirely designed and produced in-house. Its defining feature is the brand’s patented Resonance Clutch Spring, which connects two independent regulating systems, enabling the balance wheels to oscillate in harmonic resonance. This phenomenon enhances chronometric stability and is visually showcased by a pusher at 2 o’clock that resets both seconds hands simultaneously—a dramatic demonstration of mechanical synchronicity in action. Operating at 3.5 Hz (25,200 vph) and offering a 48-hour power reserve, the movement transforms a centuries-old scientific principle into contemporary watchmaking mastery.

Craftsmanship remains central to ARMIN STROM’s ethos. The bridges feature hand-polished bevels, black-polished screws, perlage, and circular graining, with Geneva stripes enriching the reverse side. As with every ARMIN STROM timepiece, each watch is assembled twice, ensuring absolute performance and finishing quality. This meticulous approach, combined with the vibrant ruby dial, creates a visually dynamic composition—a living interplay between stone, metal, and motion.

Encased in a 43 mm stainless steel case and fitted with a grey Alcantara strap featuring white stitching, the Mirrored Force Resonance Ruby delivers both presence and refinement. It is not merely a new dial variation, but an artistic expression grounded in horological integrity—an encounter between natural geology and mechanical resonance, distilled into a timepiece of exceptional character.

The quick-release strap system allows wearers to effortlessly adapt the watch to any mood, outfit, or occasion, transitioning seamlessly between sporty casualness and discreet, refined elegance.

While the exterior boasts a contemporary, relaxed style, the heart of the watch remains deeply committed to haute horlogerie. The in-house manual-winding caliber is gloriously on show through the display back, showcasing finger bridges—historically typical of Romain Gauthier’s birthplace, the Vallée de Joux—reinterpreted with a modern "stepped" architecture. Each Grade 5 titanium bridge is meticulously finished by hand, featuring a highly original dimpled texture achieved through a special hand-engraving technique, set against a beautifully hand-frosted movement mainplate.

Technically astute, the timepiece is equipped with a clever stop-seconds mechanism that uses a snail cam—a nod to the brand’s acclaimed Logical One. Pulling out the crown stops the balance wheel, while pushing it back in prompts the snail cam to turn, delivering an active impulse to help the movement start beating again instantly. Offered as part of the brand's permanent, non-limited collection, the C by Romain Gauthier Titanium Edition 39.5 represents a masterful synthesis of superlative hand-finishing and modern, adaptable luxury.
