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.

Chromatic Precision: Armin Strom Orbit in Lime & Ice

Armin Strom, the independent Swiss watchmaker renowned for its openworked designs and mechanical innovation, proudly unveils two striking new additions to its System 78 collection: the Orbit Lime Green and Orbit Ice Blue.

These limited edition timepieces—each restricted to just 20 pieces worldwide—introduce vibrant new fumé dials that blend bold aesthetics with technical mastery. The Lime Green model radiates energy and modernity, while the Ice Blue version offers a serene and sophisticated presence. Both dials feature a gradient effect that transitions from vivid color at the center to deep black at the edges, enhancing the visual depth of the openworked design.

A World-First Date Display on Demand

At the heart of both models lies the Armin Strom Manufacture Caliber ASS20, the world’s first movement to feature a date display on a ceramic bezel that appears only when activated. A pusher at 10 o’clock engages the date hand, which points to the current date and advances automatically at midnight. A second press returns the hand to its neutral position, offering a playful yet practical complication powered by a column-wheel mechanism.

The movement also incorporates Armin Strom’s patented Equal Force Barrel, delivering consistent energy for a stable 72-hour power reserve.

Haute Horology Craftsmanship

Each Orbit model is meticulously hand-finished at Armin Strom’s Manufacture in Biel/Bienne, employing traditional techniques such as anglage, perlage, and circular graining. The off-center dial is paired with rhodium-coated hands enhanced with Super-LumiNova®, ensuring legibility and elegance. The watches are housed in a stainless steel case with a fixed ceramic bezel and come with a matching bracelet featuring a double-folding clasp.

The Science of Movement

Founded in 1967 and revitalized in 2009, Armin Strom continues to push the boundaries of horological innovation. Every timepiece is designed, developed, and assembled in-house, reflecting the brand’s commitment to transparency, craftsmanship, and mechanical excellence.

True Beat in Color: Arnold & Son Presents DSTB 42 Mint Green and Ascot Blue

Arnold & Son continues to push the boundaries of mechanical artistry with the launch of two new interpretations of its iconic DSTB 42 timepiece. The DSTB 42 Red Gold Mint Green and DSTB 42 Platinum Ascot Blue editions bring a fresh chromatic perspective to one of the brand’s most emblematic complications: the true beat seconds.

A tribute to the marine chronometers once supplied by John Arnold to the Royal Navy, the true beat seconds—also known as “deadbeat seconds”—is a rare and technically demanding feature. Unlike the sweeping motion of a conventional seconds hand, this mechanism causes the hand to jump precisely once per second, echoing the cadence of traditional precision timekeeping.

In these two new editions, Arnold & Son elevates the complication with bold color and refined materials. The Red Gold Mint Green model features a vibrant mint green dial housed in an 18K red gold case, while the Platinum Ascot Blue edition pairs a deep blue dial with the cool elegance of platinum 950. Both dials are grained for a rich, light-catching texture and are punctuated by a white opal subdial for hours and minutes, offset at 5 o’clock.

The true beat seconds mechanism is fully visible on the dial side, supported by three openworked bridges crafted in solid gold—red gold for the Mint Green edition and white gold for the Ascot Blue. The seconds hand travels along a railway track between 9 and 12 o’clock, orchestrated by a dedicated mechanism that mimics the precision of an escapement. The anchor-shaped counterweight, a nod to Arnold & Son’s maritime heritage, adds a poetic touch to the technical display.

Powering both models is the in-house A&S6203 automatic movement, beating at 4 Hz and offering a 55-hour power reserve. The movement is meticulously finished with Geneva stripes, perlage, polished angles, and a 22K gold oscillating weight.

Each watch is paired with a hand-stitched alligator leather strap—green for the red gold version and ink blue for the platinum—and secured with a matching pin buckle. Both editions are strictly limited to 18 pieces worldwide, underscoring their exclusivity and collectability.

With the DSTB 42 Red Gold Mint Green and Platinum Ascot Blue, Arnold & Son reaffirms its commitment to blending horological innovation with bold design. These timepieces are not only feats of mechanical engineering but also vibrant expressions of individuality and craftsmanship.
