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..

Chronoswiss proudly presents the Delphis Art Deco, a striking new edition that bridges the design philosophy of the Roaring Twenties with modern mechanical watchmaking. Housed in a 42mm Grade 5 titanium case with a matte finish, this limited-edition timepiece pays homage to an era celebrated for its architectural clarity, geometric symmetry, and creative freedom. Combined with a black nubuck strap, the piece achieves a balanced, modern presence that elevates the emblematic Delphis complication first introduced in 1996.

At the center of the watch is a lasered, nickel-coated main dial featuring a subtle three-dimensional texture in a refined grey tone. The upper stage hosts the iconic Delphis display: a digital jumping hour at 12 o'clock, a sweeping retrograde minute hand, and a subdial at 6 o'clock. Highlighted in a captivating "Art-Deco Blue" lacquer over a hand-guilloché base engraved on century-old machines at Atelier Lucerne, the subdial is beautifully accented by a gold-plated minute ring that adds a warm, geometric contrast.

Beating inside is the manufacture automatic Caliber C.6004, developed in partnership with La Joux-Perret. Visible through the transparent sapphire crystal caseback, this 37-jewel movement delivers a 55-hour power reserve and features ruthenium-plated bridges decorated with Geneva stripes and a skeletonized tungsten rotor. The 17-piece solid titanium case incorporates Chronoswiss’s signature onion crown, patented Autobloc screw lugs, and a robust 10 bar (100m) water resistance rating.

Strictly limited to just 150 pieces worldwide, the Chronoswiss Delphis Art Deco is a sophisticated mechanical tribute to 1920s design reimagined for contemporary collectors. Blending heritage hand-craftsmanship with modern engineering, it represents a bold new chapter for one of the brand's most recognizable models. The Delphis Art Deco is now available for order through authorized Chronoswiss retailers and official channels.

Armin Strom introduces the Tribute 1 Green, a refined dress watch that pays homage to the timeless beauty of nature. Limited to just 50 pieces, this new release brings forest-inspired tones to the brand’s most elegant collection, combining artisanal craftsmanship with modern mechanical innovation.

A Forest-Inspired Masterpiece

The Tribute 1 Green features a striking off-centre dial in forest green, adorned with a hand-engraved grain d’orge guilloché pattern and crisp white Roman numerals. A frosted subdial adds depth and texture, while the green Alcantara leather strap with off-white stitching completes the composition with understated sophistication. The openworked motor barrel, secured by a polished finger bridge in stainless steel, echoes the case design and showcases Armin Strom’s signature fusion of symmetry and mechanical artistry. The 38 mm stainless steel case, with anti-reflective sapphire crystals front and back, ensures optimal clarity and elegance.

Exceptional Performance

At the heart of the Tribute 1 Green is the manual-winding Manufacture Caliber AMW21, offering an impressive 100-hour power reserve. This is made possible by the brand’s patented equal force barrel, designed for efficiency and compactness. Operating at 25,200 vibrations per hour (3.5 Hz), the movement reflects Armin Strom’s technical mastery, with 97% of components produced in-house.

Haute Horlogerie, Hand-Finished

Every Tribute 1 Green is a testament to traditional watchmaking. The case features brushed and polished surfaces, finished entirely by hand. Inside, the movement is decorated with Geneva stripes, circular graining, and a mirror-polished finger bridge, all executed by Armin Strom’s skilled artisans.

True to the brand’s commitment to excellence, each watch is assembled twice—once for mechanical precision and again after decoration—to ensure the highest standards of performance and aesthetics.

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.
