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 continues its mastery of ornamental stones with the launch of the Ultrathin Tourbillon Onyx. Available in 18-carat 5N red gold or 950 platinum, this exquisite timepiece is limited to just eight pieces per version. The design features a broad dial crafted from polished natural onyx, offering an intense black backdrop that beautifully contrasts with a unique matt-finished sub-dial.

At the heart of this creation is the A&S8300 manufacture calibre, which stands as one of the slimmest flying tourbillon movements in the industry at only 2.97 mm thick. Technical refinements to the regulating organ and tourbillon cage have boosted the power reserve to an impressive 100 hours. The flying tourbillon at 6 o'clock remains a visual highlight, featuring a hand-engraved yellow gold bridge and a cage design inspired by John Arnold’s historic maritime chronometers. The watch is completed with a hand-stitched black alligator strap and a matching precious metal clasp.

Chronoswiss marks a definitive leap into the future of independent watchmaking with the introduction of the PULSE GMT, a collection that represents one of the most progressive chapters in the brand's history. Inspired by the mechanical spirit of the 1999 Tora icon, this new series redefines traditional design codes through a radically modern lens while maintaining the brand's independent spirit. The collection is built specifically for global travelers and collectors who move between continents and time zones, requiring a sophisticated mechanical companion.

The PULSE GMT features a bold, sculptural case construction that seamlessly integrates the first full metal bracelet in Chronoswiss history. This architectural approach ensures a unified presence on the wrist, blending the iconic onion crown and coin-edge bezel with contemporary lines. Whether crafted from high-strength Grade 5 Titanium for daily wear or solid 18-carat 5N Gold, the 41mm case offers a powerful physical and visual statement.

At the heart of the collection beats the Manufacture Caliber C.6002, an automatic movement developed exclusively with La Joux-Perret. This dedicated mechanical construction provides a true dual-time display, featuring a 24-hour second time zone on the left and a 12-hour home time on the right, all unified by central minutes and seconds. With a 55-hour power reserve and water resistance up to 10 bar, the movement is designed for movement and mechanical clarity.

The collection showcases the height of Lucerne craftsmanship through two distinct dial interpretations. The Silver Guilloche edition celebrates pure mechanical texture with hand-guilloché patterns cut on century-old machines, while the Enamel Sky Gold features the rare art of paillonné enamel. This demanding craft embeds gold stars within layers of translucent fire enamel over a guilloché base, creating a celestial display designed to last for centuries.

Moritz Grossmann proudly unveils the TREMBLAGE Green, a limited edition timepiece that redefines elegance through heritage craftsmanship and a bold new aesthetic. Available in rose gold and white gold, with only 8 pieces of each, this extraordinary watch is a tribute to the art of traditional engraving and the timeless beauty of horological design.

At the heart of the TREMBLAGE Green lies a dial crafted from German silver, meticulously hand-engraved using the rare tremblage technique. This centuries-old method creates a fine, matte texture that diffuses light with a soft, meditative glow. The dial is finished in a deep, complex green—symbolizing renewal, harmony, and depth—making it a standout piece that remains understated and refined.

Encased in a 41 mm case of 750/000 rose or white gold, the watch is powered by the in-house calibre 100.1, a hand-wound movement visible through a sapphire crystal case back. Every component is hand-finished, from the Glashütte ribbing and polished bevels to the engraved balance cock. The watch features hours, minutes, and a small seconds display with a stop-second function, all operated via a gold crown and lateral pusher.

Completing the look is a hand-stitched dark brown alligator leather strap, offering both comfort and sophistication. The TREMBLAGE Green is not just a timepiece—it is a celebration of “Schönstes deutsches Handwerk” (the finest German craftsmanship), brought to life with modern sensibility and timeless appeal.
