Chronoswiss has officially introduced the Opus Dakar Sundown, a striking new interpretation of the celebrated Opus Dakar that captures the fleeting magic of sunset over the desert. Housed in a distinctive 41mm two-tone case crafted from stainless steel and 18ct red gold, the timepiece masterfully blends the rugged spirit of adventure with refined luxury. The warm glow of precious metal flows seamlessly into the robust steel construction, mirroring the final golden rays dancing across endless dunes. This ultimate celebration of contrasts is beautifully completed by a sand-colored nubuck leather strap that evokes the warm tones of sunlit, weathered terrain.

At the heart of the watch beats the Chronoswiss Manufacture Caliber C.741S, a fully skeletonized automatic chronograph movement that transforms every measurement of time into a visual spectacle. Designed for legibility and visual complexity, the central chronograph seconds hand sweeps the openworked dial in harmony with a 30-minute counter at 12 o'clock and a 12-hour counter at 6 o'clock. A running small seconds display at 9 o'clock provides a constant indication of the movement's heartbeat, while a highly unique, analogue pointer date display at 3 o'clock enhances its everyday practicality.

The skeletonized, CVD-coated brown dial draws inspiration from the rich palette of the desert, where warm tones create a composition that is both timeless and adventurous. By exposing the intricate mechanics beneath the surface, every skeletonized bridge, wheel, and component directly contributes to a captivating, mechanical canvas. The hands are crafted in the elegant Breguet Losange shape and rhodium-plated to ensure striking contrast against the dark, galvanic black perlage of the base plate.

Crafted in solid 23 pieces, the 41mm case features an 18ct red gold bezel with partial knurling, a screw-down case back with a red gold coin-edge ring, and Chronoswiss’s iconic onion crown. The total weight of gold used in this exceptional construction is 21.4 grams. Offering a water resistance of 3 bar (30 meters), the watch is equipped with screw-in lugs utilizing the patented Autobloc system. For over three decades, the Opus collection has embodied the bold spirit of Chronoswiss; the Opus Dakar Sundown brilliantly reimagines this legacy, shaped by craftsmanship and illuminated by one of nature's most spectacular moments.

To celebrate 17 years since its rebirth in 2008, Moritz Grossmann unveils a horological milestone: the PERPETUAL CALENDAR. This grand complication embodies the brand's philosophy of timeless precision, combining traditional craftsmanship with modern innovation.

The PERPETUAL CALENDAR is engineered to automatically account for the varying lengths of months and leap years, requiring no manual correction until the year 2100. This makes it one of the most technically demanding and revered complications in fine watchmaking.

The dial is a study in symmetry and clarity. A full 1–31 date scale encircles the dial, with a cup-shaped indicator framing the current date. The month and weekday are displayed on subdials at 3 and 9 o'clock, decorated with Azurage finishing. Leap year and day/night indicators are integrated into the subdials. At 12 o'clock, a poetic moon phase display features a mother-of-pearl moon gliding across a goldstone sky.

At the heart of the watch is the newly developed Calibre 101.13, a hand-wound movement based on the 100.1 calibre with an added perpetual calendar module. It comprises 401 components — 211 for the calendar module and 190 for the base movement. The movement features optimised stopwork, an integrated manual winder, and an escape wheel bearing in the barrel bridge. The finishing adheres to traditional Glashütte standards, with untreated German silver plates, raised gold chatons, and hand-engraved details.

All calendar functions can be adjusted via recessed correctors on the case, operated with a dedicated tool. A sum corrector allows for quick synchronization of all indicators after periods of inactivity.

The PERPETUAL CALENDAR is available in three elegant variants: rose gold with argenté dial (Ref. MG-003906), rose gold with anthracite dial (Ref. MG-003907), and platinum with argenté/anthracite dial (Ref. MG-003904). Each model is paired with a hand-stitched dark brown alligator leather strap and a matching prong buckle.

Moritz Grossmann continues to honour its namesake's 19th-century legacy with a commitment to "Schönstes deutsches Handwerk" — the finest German craftsmanship. The PERPETUAL CALENDAR is a testament to this enduring vision, offering collectors a timepiece that is as poetic as it is precise.

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.

Following its global debut last night, Greubel Forsey is proud to unveil a new expression of the Balancier 3. Limited to just 22 timepieces, this latest edition continues the evolution of the movement first introduced in 2023, pushing the boundaries of hand-finishing by introducing a treatment never before executed at the Atelier: a frosted titanium bridge, hand-finished with a steel brush across its entire curved surface.

Housed in the signature 41.50mm Convexe titanium case, the Balancier 3 combines this innovative finishing with vibrant blue tones to create a three-dimensional landscape where high-performance chronometry meets unparalleled ergonomic design. The variable geometry of the case is engineered to follow the natural curvature of the wrist, while the multi-level openworked bridges provide a sense of visual lightness despite the movement's technical density.

Performance without compromise defines the heart of the Balancier 3, where technical density meets a striking sense of visual openness. This hand-wound movement is composed of 282 individual parts, featuring two series-coupled fast-rotating barrels that deliver a 72-hour chronometric power reserve. At its core, the in-house variable-inertia balance wheel measures 12.60mm in diameter and is meticulously fitted with six gold mean-time screws to ensure absolute precision.

The functional layout remains faithful to its original architectural concept, displaying hours and minutes on a suspended central bridge alongside a rotating small seconds disc. While the dial side offers a three-dimensional view of the mechanics, the movement side reveals a power-reserve indication integrated into the frosted titanium bridges. Every element, from the involute circle profile gearing to the olived-domed jewels, represents a singular vision of horological excellence and the "Art of Invention."

Independent manufacture Romain Gauthier has unveiled its latest horological evolution with the release of the C by Romain Gauthier Titanium Edition 39.5. This new iteration introduces a highly anticipated, more compact 39.5 mm Grade 5 titanium case designed to sit effortlessly on a broader range of wrist sizes. Embodying the core philosophy of the collection, the timepiece is built for everyday wearability, blending high-end mechanics with a casual, modern design language that seamlessly integrates into daily life.

Enhancing this newfound versatility, the manufacture introduces its very first interchangeable rubber strap system alongside three expressive new colorways: vibrant blue, energetic orange, and subtle pink. These eye-catching color accents on the dial are matched with corresponding Super-LumiNova hues at night, offering a fresh, lifestyle-oriented aesthetic. The quick-release strap system allows wearers to effortlessly adapt the watch to any mood, outfit, or occasion, transitioning seamlessly between sporty casualness and discreet, refined elegance.

While the exterior boasts a contemporary, relaxed style, the heart of the watch remains deeply committed to haute horlogerie. The in-house manual-winding caliber is gloriously on show through the display back, showcasing finger bridges—historically typical of Romain Gauthier’s birthplace, the Vallée de Joux—reinterpreted with a modern "stepped" architecture. Each Grade 5 titanium bridge is meticulously finished by hand, featuring a highly original dimpled texture achieved through a special hand-engraving technique, set against a beautifully hand-frosted movement mainplate.

Technically astute, the timepiece is equipped with a clever stop-seconds mechanism that uses a snail cam—a nod to the brand’s acclaimed Logical One. Pulling out the crown stops the balance wheel, while pushing it back in prompts the snail cam to turn, delivering an active impulse to help the movement start beating again instantly. Offered as part of the brand's permanent, non-limited collection, the C by Romain Gauthier Titanium Edition 39.5 represents a masterful synthesis of superlative hand-finishing and modern, adaptable luxury.
