Arnold & Son Nebula 40 Steel, Blue Edition Design Philosophy: Radiating Harmony

JUNE 10 2025 | Novelties

The watch features a star-shaped arrangement of seven bridges, radiating from the center like a nebula, giving it both structural integrity and visual depth.

The movement is laid out with four lines of symmetry, aligning the barrels, balance, and small seconds for a harmonious aesthetic.

Technical Excellence: A&S5201 Calibre

Dual barrels provide an impressive 90-hour power reserve.

Components are arranged in a kinematic chain around the edge, enhancing both function and form.

The crown mechanism is inverted and placed on the case-back side for symmetry with the first wheel at 9 o’clock.

Aesthetic Details

The lower levels of the movement are treated with a rich blue PVD, contrasted by palladium-finished bridges and components.

Includes horizontal satin brushing on the dial side and Arnold & Son’s signature ‘Rayons de la Gloire’ motif on the reverse.

The 40 mm diameter and 9.10 mm thickness ensure elegance on the wrist.

Strap & Bracelet Options

Available with a blue alligator leather or rubber strap.

Also offered with a three-link steel bracelet that highlights the watch’s symmetry and skeletonized beauty.

Arnold & Son Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

Arnold & Son unveils the Perpetual Moon 41.5 Cliff Grey Edition, a poetic tribute to the cliffs of Cornwall and the legacy of John Arnold, the renowned marine chronometer-maker. This limited edition of 28 pieces in 18-carat red gold reflects the brand’s deep connection to celestial navigation and English heritage.

The dial is adorned with the exclusive Stellar Rays motif, a textured pattern that plays with light through layered transparent lacquer. Its Cliff Grey tone evokes the misty British coastline, while the moon phase display—among the largest in watchmaking—glows in mother-of-pearl enhanced with Super-LumiNova. Set against a midnight-blue sky, the moon is surrounded by hand-painted constellations, Ursa Major and Cassiopeia, symbols of guidance and exploration.

The case, measuring 41.5 mm in diameter, is sculpted with refined lugs and a slim bezel that opens up the dial to its full celestial display. On the reverse, a secondary moon-phase indicator allows for precise adjustment of the moon’s age.

Inside, the manually wound A&S1512 calibre offers a 90-hour power reserve and tracks lunar cycles with remarkable precision. So accurate is its mechanism that it would take 122 years of continuous operation to accumulate a single day’s deviation from the actual lunar cycle.

Crafted entirely in-house in La Chaux-de-Fonds, the movement is finished with Geneva stripes, blued screws, and circular graining. The watch is completed with a warm grey alligator leather strap and a matching red gold pin buckle.

The Cliff Grey Edition is a refined expression of Arnold & Son’s dedication to craftsmanship, astronomy, and timeless design.

Fully-integrated manufacture brand Armin Strom celebrates 15 years and heads into the future

Armin Strom co-founders Serge Michel and Claude Greisler look back on 15 years of achievements including 17 exclusive movements, patents, unique designs and 97% in-house production depth. 15 years ago, Armin Strom transformed from a one-man show to a fully integrated manufacture brand when entrepreneur Serge Michel and master watchmaker Claude Greisler took over the reins.

Since 2009, the two childhood friends have been dedicating their lives to the science of movement, building up an independent manufacture with a team of 38, including 22 skilled watchmakers able to turn raw steel bars into hundreds of complex, interconnected watch components. So far, this has resulted in 17 brand-unique different calibres with a signature open-worked design divided among the brand’s three main pillars: System 78, Resonance and Masterpiece.

Celestial Contrast: Armin Strom Dual Time GMT Resonance Aventurine

Armin Strom presents a new interpretation of its Dual Time GMT Resonance, distinguished by a dial crafted from aventurine—a material that captures the richness and mystery of a star-filled sky. Formed through a meticulous process that blends centuries-old glassmaking with modern precision, aventurine reveals a surface alive with light. The result is a dial that evokes a night sky in motion, creating a refined contrast with the architectural symmetry of the resonance movement. This celestial texture is enhanced by the warm tones of the movement: the rose gold-coloured mainplate adds depth beneath the dial-side display, while rose gold-coloured hands and applied indexes introduce clarity and visual identity. Together, these elements create a balanced interplay between cool luminosity and warm mechanical presence. Housed in a 39 mm stainless steel case and paired with a dark grey alligator strap, the Aventurine edition offers a contemporary and restrained frame, allowing the dial's dimension and the movement's symmetry to take centre stage.

Resonance Across Time Zones
Powering the watch is the manual-winding manufacture calibre ARF22, entirely designed, developed and produced in-house. Its patented resonance clutch—a signature Armin Strom innovation—synchronises two independent regulating systems, allowing both balance wheels to oscillate in perfect harmony. This constant interaction elevates chronometric stability, transforming a rare physical phenomenon into a practical advantage. Each time zone features its own hours, minutes and day/night indicator, offering intuitive functionality for travellers. Operating at 3.5 Hz (25,200 vph) with a 42-hour power reserve, the ARF22 unites scientific ingenuity with everyday usability.

Finishing in Depth
Visible through sapphire crystals on both sides, the movement reveals Armin Strom's signature open-worked architecture and hand-finishing. The rose gold-coloured mainplate establishes a warm, luminous foundation on the dial side, while matching gear-train bridges on the reverse side echo this tone, creating a cohesive visual language. This harmony of colour and structure accentuates depth and contrast, reinforcing the three-dimensional expression of the calibre and the brand's commitment to the Science of Movement. On the dial side, the mirror-polished balance bridge, finished with hand-bevelled edges, stands out as a focal point, its steel surface catching the light in striking counterpoint to the warm rose gold-coloured mainplate beneath. Rhodium-coated and steel components introduce a refined metallic grey tone, balancing the overall composition. Additional hand-polished bevels, black-polished elements, circular graining and perlage enrich the composition, while the reverse side features Côtes de Genève, further emphasising the movement's refinement. As with all Armin Strom timepieces, each watch is assembled twice to ensure both mechanical precision and finishing excellence.

The new Dual Time GMT Resonance Aventurine is offered in a strictly limited edition of 15 pieces.

Longitude Titanium - High-sea watchmaking

Arnold & Son, a benchmark in classic fine watchmaking, is exploring uncharted territory on the map of horology. Longitude Titanium is a sports-chic COSC-certified chronometer with a 42.5 mm titanium case. The dial of Longitude Titanium is vertical satin-finished in a continuation of the bracelet’s finish, which is subtly intersected by the polished edges of its links. With a power-reserve display at 12 o’clock and an imposing seconds counter at 6 o’clock, Longitude Titanium pays tribute to John Arnold’s marine chronometers, his revolutionary vision and his decisive role in calculating longitude at sea.
The aesthetics and construction of John Arnold’s marine chronometers were necessarily classic and functional, and were adapted to the harsh conditions of the high seas. Longitude Titanium, a contemporary interpretation of the great English watchmaker’s work, coherently combines this naval heritage with a refined design and highly resistant materials. The movement’s ‘chronometer’ certification is an essential addition to this scene, with its historical ties to Arnold’s creations and his quest for accuracy.
