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.

Armin Strom Introduces The One Week Skeleton

The Armin Strom One Week Titanium Skeleton, an openworked masterpiece now fully skeletonized to reveal the intricate heart of its mechanics, combines striking design with precision engineering. Encased in lightweight titanium grade 5, it balances strength with comfort, providing a feeling of lightness that makes it easy to wear all week long.

The Armin Strom One Week Titanium Skeleton is a showcase of skeletonization, a technique that is rooted in Mr. Armin Strom’s philosophy and heritage. He sought to enhance depth and three-dimensionality while avoiding see-through to maintain elegance.

The 2023 One Week was already openworked by nature, but this version goes even further, removing more material to highlight the movement’s complexity. Few watches combine openworking and skeletonization at this level. The small seconds dial is skeletonized, revealing the power reserve level and the escapement wheel for a 3D mechanical animation. The mainplate and the barrels are also skeletonized enhancing aesthetics. Thanks to this skeletonization, the power reserve indicator is highlighted as well as the cone mechanism, reminiscent of ancient pocket watches. A major highlight is the case back, offering a mesmerizing view of the entire mechanism.

With a 7-day power reserve, this watch keeps time accurate for an entire week without needing winding. The hand-finished details reflect the level of craftsmanship behind its design. Limited to 100 pieces, the One Week Titanium Skeleton offers a refined, functional timepiece that blends robustness and comfort in a minimalist package.

The Golden Era Begins: Mirrored Force Resonance in Rose Gold

Armin Strom proudly unveils a new expression of its horological mastery with the launch of the Mirrored Force Resonance in 18K Rose Gold. This limited edition marks a significant milestone for the brand’s most iconic timepiece, blending technical innovation with timeless elegance.

A First in Rose Gold

For the first time, Armin Strom’s signature case is crafted from 18K rose gold, offering a warm and luxurious aesthetic. The 43 mm case features alternating brushed and polished finishes, enhancing its sculptural presence. Beneath the sapphire crystal, a bold black off-centre dial showcases a handcrafted sunray guilloché pattern, created using a traditional rose engine lathe. A chapter ring with circular finishing adds depth and texture, while a dark grey Alcantara strap completes the refined look.

Resonance Engineered for Performance

At the heart of this timepiece lies the Caliber ARF21, a manually wound movement that exemplifies Armin Strom’s pioneering work in resonance watchmaking. The patented Resonance Clutch Spring synchronizes two independent balance wheels, enhancing precision and chronometric stability. A pusher at 2 o’clock resets the twin seconds counters, offering a visual demonstration of the resonance mechanism’s accuracy.

Craftsmanship Without Compromise

Every surface of the movement is meticulously hand-finished, visible through sapphire crystals on both sides of the case. Techniques such as hand-beveling, black polishing, perlage, and circular graining highlight Armin Strom’s commitment to haute horology. Each watch is assembled twice to ensure mechanical integrity and flawless finishing.

Limited Edition of 15 Pieces

This exclusive release is limited to just 15 pieces, each priced at CHF 88,000. It represents a rare opportunity to own a timepiece that embodies both technical brilliance and artisanal beauty.
A Statement from Claude Greisler

“The introduction of an 18-karat rose gold case marks a significant milestone for the Mirrored Force Resonance series. This choice of material not only enhances the aesthetic appeal but also underscores our commitment to offering a diverse range of options to our clientele,” said Claude Greisler, Co-Founder and Master Watchmaker at Armin Strom.

gérald genta unveils the Geneva Time Only — sculptural elegance distilled into a 38 mm cushion‑case

The Maison gérald genta expands the Geneva collection with the Geneva Time Only, a new 38 mm creation in warm rose gold 4N and cool white gold, translating the line’s sculptural language and “l’esprit de Genève” into an essential, everyday expression.

“I wanted to capture the intuitive, instinctive genius and artistry of Mr. Genta,” says Matthieu Hegi, Artistic Director at La Fabrique du Temps Louis Vuitton, who leads the Geneva collection’s creative direction.

The updated cushion case—neither round nor square—features softened contours, a refined gadroon and a new single, broader lug on each side, striking a rare balance of daring and discretion. Light plays across polished and satin surfaces, while the collection’s signature two‑segment minute track forms a subtle optical illusion as the outer track follows the cushion silhouette and the inner ring remains perfectly circular. The grained brass dial carries a gentle fumé gradient—lighter at the center, darker at the edge—for tonal depth.

At just 8.15 mm thick, the 38 mm case slips neatly under a cuff; both models are fitted with rounded, mirror‑polished solid‑gold hands and applied indexes and tone‑on‑tone calfskin straps. Under the dial, the GG‑005P automatic calibre—Zenith Elite–based with redesigned bridges and a reworked oscillating mass—beats at 4 Hz with a 50‑hour power reserve (158 components, 27 jewels), visible through the sapphire caseback. Water‑resistance is 30 m.
