Greubel Forsey GMT Balancier Convexe

Arnold & Son proudly presents the Longitude Titanium 5°W Edition, a timepiece inspired by the marine chronometers crafted by John Arnold in the late 18th century. These instruments revolutionized navigation and played a pivotal role in the British Navy’s mastery of the seas.

This limited edition of 38 pieces combines grade 5 titanium with an 18K red gold bezel ring, echoing the elegance of historical chronometers. The Lizard Point Grey dial, with its vertical satin finish, evokes the stormy hues of the North Atlantic near Lizard Point—the southernmost tip of mainland Great Britain at 5° west longitude.

Inside beats the A&S6302 calibre, an in-house automatic movement certified by the COSC as a chronometer. It offers a 60-hour power reserve, a power-reserve indicator at 12 o’clock, and a small seconds subdial opposite. Through the sapphire case back, the palladium-plated bridges and skeletonized 22K red gold oscillating weight—engraved with a ship and sextant motif—reveal the artistry of Arnold & Son.

Water-resistant to 100 meters, the Longitude Titanium 5°W features an interchangeable strap system, allowing effortless transition between an anthracite grey alligator leather strap and a titanium bracelet.

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 has masterfully fused its revolutionary resonance technology with a bold, contemporary aesthetic in the new Mirrored Force Resonance Red. Limited to just 15 pieces worldwide, this rare masterpiece introduces a striking off-centre guilloché dial in vibrant red. By pairing traditional hand-crafted artistry with the brand’s signature open-worked design, this timepiece breathes dynamic new energy into Armin Strom's celebrated dual-balance mechanism, creating a captivating dialogue between classic hand-finishing and cutting-edge mechanical architecture.

The brilliant red dial is hand-crafted on a traditional, manually operated rose engine lathe, engraving a radiating pattern that catches and plays with light in captivating reflections. Encircled by black azuré (蝸形紋) chapter rings and topped with faceted, floating index markers, the dial's layout creates a stark, three-dimensional contrast that maximizes both visual depth and legibility. Housed in a polished 43 mm stainless steel case, the movement's technical architecture is framed by anthracite-coated bridges and paired with a dark grey Alcantara strap—ensuring that the vibrant red dial and the synchronized dance of the resonance mechanism remain the undisputed center of attention.

At the heart of this technical marvel lies the in-house Calibre ARF21, a hand-wound movement that integrates two completely independent movements within a single calibre. Connected via Armin Strom's patented Resonance Clutch, the two opposing balance wheels transfer vibrations to enter and maintain a perfect state of harmonic resonance. This physical synchronization significantly improves chronometric stability and rate consistency over time. To let wearers witness this horological phenomenon in action, a pusher at 2 o'clock activates a flyback mechanism, resetting both independent seconds hands to zero simultaneously so their perfect synchrony can be monitored in real-time.

Every millimeter of the Mirrored Force Resonance Red showcases Armin Strom's uncompromising dedication to haute horology standards, featuring meticulous hand-polished bevels, perlage, circular graining, and mirror-black polished screws. On the reverse side, the main plate features technical inscriptions rendered in three-dimensional relief, rising directly from the metal's surface. As is tradition for the Swiss manufacture, each watch is assembled twice to guarantee absolute precision. For collectors seeking the pinnacle of independent Swiss watchmaking, this 15-piece limited edition represents a perfect harmony of mechanical science and artistic expression.

Greubel Forsey proudly unveils the QP Balancier, a revolutionary interpretation of the perpetual calendar that merges intuitive functionality with uncompromising chronometric performance. Limited to just 22 pieces in white gold, this timepiece represents a new pinnacle in haute horlogerie.

At the heart of the QP Balancier lies Greubel Forsey’s patented Mechanical Computer, a 25-part mechanical brain that “understands” the rules of the Gregorian calendar. This innovation allows the watch to adjust instantly in either direction, restart flawlessly after months unwound, and remain programmed until February 28, 2100—all without the need for pushers or complex crown positions.

The QP Balancier integrates 12 indications—including hours, minutes, seconds, power reserve, day, date, month, leap year, day/night, 24-hour display, calendar year, and a patented function selector—into a single crown interface. This makes it the most user-friendly perpetual calendar ever created, eliminating the need for manuals or reset tools.

Aesthetically, the watch is a study in purity and harmony. Its multi-level gold dial presents calendar information in a clear, linear format, flanked by leap year and day/night indicators. The tactile feedback during quick-correction mode offers a unique sensory connection between wearer and mechanism.

Housed in a 45.1 mm white gold case, the QP Balancier features Greubel Forsey’s signature 30° inclined balance wheel, a high-mass, variable-inertia system with gold mean-time screws. The movement comprises 612 hand-finished components, including twin fast-rotating barrels that deliver a 72-hour chronometric power reserve.

With the QP Balancier, Greubel Forsey has not only redefined the perpetual calendar—it has perfected it.

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".
