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.

Arnold & Son Unveils the Ultrathin Tourbillon Onyx Edition: When Darkest Black Becomes Colour

Arnold & Son continues its mastery of ornamental stones with the launch of the Ultrathin Tourbillon Onyx. Available in 18-carat 5N red gold or 950 platinum, this exquisite timepiece is limited to just eight pieces per version. The design features a broad dial crafted from polished natural onyx, offering an intense black backdrop that beautifully contrasts with a unique matt-finished sub-dial.

Technical refinements to the regulating organ and tourbillon cage have boosted the power reserve to an impressive 100 hours. The flying tourbillon at 6 o'clock remains a visual highlight, featuring a hand-engraved yellow gold bridge and a cage design inspired by John Arnold’s historic maritime chronometers. The watch is completed with a hand-stitched black alligator strap and a matching precious metal clasp.

A Deeper Cut: Armin Strom One Week Skeleton Rose Gold

   

Armin Strom extends its golden era with the One Week Skeleton Rose Gold, a new interpretation of its architectural One Week design. This fully skeletonised masterpiece reveals the depths of its mechanics, paying tribute to Mr. Armin Strom’s pioneering artistry in skeletonisation—a craft at the heart of the brand’s philosophy and heritage.

For the first time, the in-house calibre appears in a solid 18K rose gold case, enriching the collection with a warmer character. Rose gold-coloured finger bridges, hands, and applied indexes mirror the tone of the case, while a sleek black textile strap provides a refined modern contrast. Measuring 41 mm in diameter, the case remains compact and ergonomic, while its skeletonised architecture gives the watch a distinctive presence—a harmonious balance of technical craftsmanship and precious metal elegance.

Seven Days of Precision
At its heart lies the hand-wound Calibre ARM21-S, a reinterpretation of Armin Strom’s first in-house calibre. Two mainspring barrels work in series to deliver a steady flow of energy for seven days, wound by two ratchet wheels visible on the dial side—a distinctive Armin Strom signature. 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. Each One Week is assembled twice—a hallmark of the brand’s commitment to mechanical precision and aesthetic integrity.

Limited to just 50 pieces worldwide, the One Week Skeleton Rose Gold continues Armin Strom’s modern gold chapter—a celebration of mechanical transparency, precision, and craft.

Moritz Grossmann Unveils TOURBILLON Titanium and TOURBILLON Tremblage: Tradition Meets Modernity

The tourbillon has long been regarded as one of the most fascinating complications in the history of watchmaking. Moritz Grossmann now reinterprets this horological icon with two extraordinary creations: TOURBILLON Titanium and TOURBILLON Tremblage. These timepieces embody the manufactory’s philosophy of blending traditional craftsmanship with contemporary aesthetics.

The TOURBILLON Titanium combines the technical sophistication of a flying three-minute tourbillon with the modern appeal of a titanium case. Its solid silver dial, adorned with a fine grain d’orge guilloche pattern, reflects the artistry of hand-guided engraving techniques. The result is a watch that is both lightweight and visually striking, offering a perfect balance of durability and elegance.

The TOURBILLON Tremblage, on the other hand, celebrates the beauty of historical handcraft. Its warm rose-toned dial is meticulously engraved using the traditional tremblage technique, creating a unique matte texture that softens light and enhances depth. Paired with a white gold case, this model exudes timeless sophistication while showcasing the manufactory’s dedication to artisanal excellence.

Both models are powered by the hand-wound calibre 103.0, featuring a flying three-minute tourbillon and patented innovations for precision timekeeping. Every component is finished by hand, from the engraved plates to the polished screws set in gold chatons, reflecting the highest standards of Glashütte watchmaking. These creations are more than timepieces—they are works of art that unite heritage and modernity in perfect harmony.
