The finesse of curves With its graceful curves and wide apertures, Ultrathin Tourbillon Skeleton also stands out for its slimness. Its new case, with a diameter of 41.5 mm and a thickness of 8.4 mm, presents the flying tourbillon calibre in its purest expression. The Ultrathin Tourbillon Skeleton collection, adorned in red gold or platinum, is issued in two limited series featuring 28 watches apiece. Arnold & Son continues its tour of the Ultrathin Tourbillon collection. The A&S8320 calibre unveils its curves, apertures and details within a 41.5 mm case in either red gold (5N) or platinum (PT 950), each released in a run of 28 timepieces. Encased in this precious housing, Arnold & Son’s flying tourbillon stands out for its finesse and precision. Finesse, because at just 3.3 mm thick, it is one of the slimmest skeleton tourbillon calibres in existence. Precision, because this one-minute flying tourbillon is assembled with a variable-inertia balance for enhanced calibration stability.

To celebrate the 20th anniversary (2004-2024), Greubel Forsey presents its 10th Fundamental Invention: the Nano Foudroyante EWT. The mechanism’s energy is managed at the nanojoule scale, significantly reducing the number of components and the overall dimensions. The result is a 37.9mm timepiece that combines the world’s first perpetual Nano Foudroyante with Greubel Forsey’s first flying tourbillon and manual wind flyback. This timepiece, set in a white gold and tantalum case, will be limited to just 11 pieces.

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.

Swiss independent watch brand Armin Strom celebrates the 15th anniversary of its fully-integrated Manufacture by reimagining its most historically significant innovation, the resonance complication, in an entirely new Dual Time GMT Resonance First Edition. The new timepiece is presented in a hotly-anticipated 39-mm case size made in 18-karat white gold and limited to 25 pieces.

A harmoniously arranged skeletonised calibre with an evolved and subtle watchmaking style. Arnold & Son has reworked its Nebula collection, giving it a more striking case with a universal diameter of 40 mm while retaining its remarkably finished movement and unique abundance of watchmaking tradition. Two versions – one with a rhodium-plated and black calibre, the other with golden accents – ensure that the Nebula 40 Steel shines bright. The aesthetics of the Nebula collection are unlike any other skeleton: its structure conveys watchmaking spirit, its style expresses unique elegance, and the overall effect is one of outstanding finesse.

The case of the Nebula collection has been redesigned, modernised and refined. With streamlined lugs, a softly rounded bezel, a more vertical case middle and a diameter of 40 mm in harmony with its thickness of just 9.10 mm, this steel case opens a new chapter for the collection. Featuring the A&S5201 skeletonised calibre offering an ultra-graphic layout, Nebula retains its identity as a watch whose movement fascinates, captivates and draws the eye into its depths.

Biel/Bienne, Switzerland, 26 June 2024: Following the inaugural redesigned One Week First Edition that made its debut in 2023, Armin Strom unveils a new version of the successor to its first-ever manufacture movement with the One Week Manufacture Edition. The highly architectural openworked movement, housed in a sleek and sporty steel case with an integrated bracelet, is now presented in a range of grey and anthracite hues. Limited to 100 pieces, the One Week Manufacture Edition foregoes colour to bring out the beauty of its uniquely constructed manual calibre.

15 years ago, independent watchmaking brand Armin Strom took a major leap that would forever change its trajectory. Realising that the path to true independence lies in mastering every step of the process, it established its very own manufacture in Biel. A year later, the first timepiece produced by its vertically integrated manufacture was unveiled: the One Week. Entirely developed and manufactured in-house and designed with symmetrical harmony in mind, it stood out thanks to its unique movement architecture featuring two barrels that together provide a seven-day power reserve. This milestone marked the beginning of many new calibres and innovations by the Armin Strom manufacture, showcasing their dedication to the science of movement and garnering the admiration and respect of even the most discerning and seasoned collectors.

The new One Week Manufacture Edition completely reimagines this milestone calibre in line with the brand’s recent bolder, more three-dimensional approach to calibre design, all in a sleek and serene execution that further highlights its ingenuity and uniqueness. The mainplate, bridges and parts, visible on the dial thanks to the openworked movement design, are anthracite PVD coated for a striking look.

As Armin Strom founder Serge Michel notes: “Collectors who missed the opportunity to get a first edition of the redesigned One Week will now have another chance. The Manufacture Edition of the new One Week will be limited to 100 pieces.”

Sporty yet classy, this model exudes calmness and serenity with its anthracite tones and the symmetrical harmony of its in-house movement.
