Greubel Forsey has officially released the Nano Foudroyante, a groundbreaking timepiece that blends cutting-edge nanomechanics with refined craftsmanship. Limited to just 22 pieces, this watch marks a major milestone for the brand, evolving from its earlier Experimental Watch Technology (EWT) concept into a fully developed and independent creation.

The Nano Foudroyante is crafted entirely in white gold and features a rhodium-finished dial with a blue minute track, blued steel hands, and a white foudroyante dial for enhanced legibility. A blue textured rubber strap completes the look, giving the watch a modern and sporty edge.

What sets this timepiece apart is its use of nanomechanics—a revolutionary approach that allows the foudroyante complication to operate using just 16 nanojoules of energy per jump. That’s 1,800 times less than traditional designs. The complication divides each second into six parts, with a red-treated hand rotating once per second, driven directly by the balance wheel. There’s no traditional gear train, just a series of ultra-efficient, low-inertia wheels.

The Nano Foudroyante also features Greubel Forsey’s first flying tourbillon, with the foudroyante dial always facing twelve o’clock for easy reading. Despite its complexity—428 components in total—the movement fits into a compact 37.90mm case, making it the smallest Greubel Forsey watch ever made.

This release is a bold statement of innovation and intent, offering collectors a rare opportunity to own one of the most advanced mechanical watches ever created..

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.

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.

In the refined sphere of independent watchmaking, DANIEL ROTH has introduced a sophisticated new expression of its Extra Plat collection, elevating the rarity of the line while retaining an understated and disciplined elegance. Rooted in the firm belief of its legendary founder that a thin dress watch represents the ultimate epitome of functional elegance, this model is meticulously designed from the ground up to balance modern sophistication with time-honored craft. Cloaked in 950 platinum—a noble metal long synonymous with rarity and traditional savoir-faire—the watch establishes a quiet yet unmistakable presence on the wrist that will immediately resonate with serious connoisseurs.

The defining silhouette of this timepiece remains the signature double-ellipse case, an iconic geometry originally created by master watchmaker Daniel Roth to beautifully frame complex horological mechanisms. To complement this distinctive shape, downward-sloping lugs have been elegantly integrated to ensure optimal wrist comfort while providing a handsome architectural contrast against the light-tan calfskin leather strap. The dial base is forged from solid white gold, displaying a mesmerizing pinstripe guilloché texture executed entirely by hand using a traditional rose engine. Each line is individually carved with masterful control over depth and spacing, beautifully bordered by a gold minute disc finished with a classic filet sauté edge and sharp black typography.

Beneath this stunning facade lies the core of the timepiece: the ultra-thin, hand-wound manufacture Calibre DR002, fully developed and assembled at La Fabrique du Temps Louis Vuitton under the expert guidance of master watchmakers Michel Navas and Enrico Barbasini. Tasked with striking the perfect balance between chronometric precision and a generous power reserve within a slim 3.1 mm structure, the watchmakers increased the movement's frequency to 4 Hz. To sustain this high frequency without sacrificing energy efficiency or structural stability, the calibre incorporates a specially refined balance wheel featuring a variable-inertia geometry and adjustable counterweights.

An open sapphire caseback reveals the true artistic discipline of the manufacture, where technical engineering and aesthetic restraint seamlessly converge. The movement's bridges are decorated with demanding hand-finishing details, most notably the internal angles which are rendered in a rare, rounded bercé form. Requiring at least twice the execution time of a standard flat bevel, this traditional decoration involves polishing a precise curved radius along the edges to create a brilliant, uniform profile. Shaped and hand-polished in-house using a traditional cabron tool, these components reinforce the brand's unwavering commitment to its guiding philosophy: "La Montre Objet d'Art".

A faithful tribute to the original model, the Tinkler 1958 repeater celebrates Angelus’s rich heritage of striking watches. Driven by a self-winding quarter-repeater movement, this double limited edition, available in gold or steel, continues the tradition of measuring instruments that built the manufacture’s reputation. From its establishment in 1891, the name Angelus has been synonymous with the chiming of a bell, a legacy reinforced by one of the Maison's first patents for a silent strike governor in 1896. Since then, repeater mechanisms have remained at the heart of Angelus collections, even being adapted into Braille-repeating watches for blinded soldiers during the First World War.

Inspired by this glorious history, Angelus is reissuing one of its rarest and most refined models: the Tinkler, based on the original 1958 edition. In 1958, Angelus filed a patent for a striking wristwatch, which was immediately followed by the original Tinkler—a pioneer of water-resistant, self-winding quarter-repeater watches. The new 38-mm case charms with a decidedly 1950s aesthetic that is clean, understated, and elegant. At 9 o’clock, the crown is balanced by a pusher that activates the quarter repeater, serving as a functional and historical hallmark of this legendary model.

The Tinkler 1958 edition is driven by the new Angelus A600 calibre, a mechanical self-winding movement that beats at 4Hz and offers a 70-hour power reserve. On request, the pusher at 9 o’clock triggers a sequence where each hour is marked by a clear strike on the first gong, followed by a double strike on two gongs to signal each quarter hour. The movement's finishing demonstrates the watchmaker's extreme attention to detail, featuring a snail-finished main plate, palladium-plated bridges adorned with Côtes de Genève, and a tungsten sunburst oscillating weight.

This new release is part of the La Fabrique line, where Angelus continues its legacy as a maker of specialty watches designed for specific activities or professional uses. The Tinkler 1958 is limited to 15 pieces in 18-carat yellow gold and 25 pieces in stainless steel, each paired with an alligator flank leather strap—ink blue for the gold version and saddle brown for the steel. Combining a modernist-style numeral 12 with exclamation-shaped hour markers at the quarter positions, the watch serves as a modern embodiment of a daring yet functional tradition.
