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.

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

Chronoswiss Unleashes the Q-Repeater – A Chiming Masterpiece combining Legacy and Future

Time is not just seen—it is heard.

Chronoswiss presents the Q-Repeater Scream and Q-Repeater Blue Note, two extraordinary Quarter Repeater timepieces that merge the sonic beauty of timekeeping with cutting-edge mechanical architecture. The watchmakers from Lucerne have created a bold reinvention of sound, design, and independent watchmaking deeply rooted in Chronoswiss history. Housed in a Grade 5 titanium case, these 42mm skeletonized masterpieces reveal the intricate mechanisms behind their chiming complication. Every press of the 10 o’clock pusher activates the mesmerizing quarter repeater function, where hammers strike to audibly indicate the hours and quarter-hours, making time a true sensory experience. At its core lies a legacy movement, rooted in the vision of Chronoswiss founder Gerd-Rüdiger Lang. First introduced in the 1990s and exclusively produced for Chronoswiss, this legacy caliber has been taken from our archives, meticulously restored, refined, and reborn in the Atelier Lucerne, making these two timepieces an extraordinary link between the past and the future.

What the watchmakers of Lucerne have achieved here is the ultimate evolution—the heart beats with the legacy of the past, carrying its passion and memories, while the body is Modern Mechanical, engineered for the next century and beyond.

Q-Repeater Scream – A Chiming Rebel
This is not your grandfather’s repeater. The Q-Repeater Scream is a wild, untamed spectacle—combining bold design and mechanical precision unlike anything in watchmaking. The multi-level dial is a skeletonized stage and at the same time part of the movement, where CVD-coated bridges in electric blue, orange, and purple hold the Paraiba green minute ring, the floating hour, as well as the small seconds rings. At 1 o’clock, the heart of this spectacle is fully visible: the striking hammers, set to release a mechanical rock concert at the press of a button.

As you can tell by the name already, it’s not just about what you see. It’s about what you hear. Every chime is a scream of innovation, breaking free from the traditions of classical repeater watches. Even the legacy movement itself becomes part of the gig, holding the Super-LumiNova blocks and hand-guilloché bridges—one of which moves when the mechanism is activated, adding to the dynamic energy of the dial. The watchmakers of Lucerne refer to the glowing ceramic blocks as “chicken heads”, a nod to the iconic amplifier knobs found on rock concert stages—designed to crank up the sound and electrify the crowd.

Caged in 42mm of titanium, the Q-Repeater Scream is limited to just 25 pieces. As only very few of the legacy movements exist this might be the final tour of the band. Each piece is a testament to mechanical defiance and unfiltered artistry. A Quarter Repeater like no other— built for collectors who dare to embrace the wild side of watchmaking.

Q-Repeater Blue Note – The Sound of Elegance
For those who seek a symphony rather than rock n roll, the Q-Repeater Blue Note takes a more refined yet equally innovative approach. Inspired by the expressive power of jazz and blues, the navy blue CVD-coated skeletonized dial and bridges which are part of the movement, play on contrasts with a silver hour ring and luminous white Super-LumiNova markers, creating a harmonious composition of mechanics and design.

In music, a blue note is an altered pitch—intentionally deviating from the standard, creating a sound that is richer, deeper, and full of soul. One could say – the Chronoswiss way of making watches – and music. The Q-Repeater Blue Note embodies this philosophy, blending traditional watchmaking with a contemporary edge, offering a timeless yet unconventional melody of time.

Like the Scream, the Blue Note features the multi-level regulator dial, a fully visible quarter repeater mechanism, and a restored historical movement, revised and refined by thewatchmakers in Lucerne. It is a timepiece that doesn’t just mark time—it composes it.

Time Reimagined, Sound Reinvented
The Q-Repeater Scream and Q-Repeater Blue Note stand as testaments to Chronoswiss’ relentless drive to push boundaries. With only 25 pieces per model, these Quarter Repeaters are more than just rare; they are audible declarations of mechanical mastery.

This is not just a watch. It is an experience. A fusion of sound and time, crafted for those who appreciate the extraordinary. Chronoswiss has never followed the expected path. The future of independent watchmaking starts here—with a chime.
