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.

ARMIN STROM introduces a compelling new interpretation of its most emblematic complication with the debut of the Mirrored Force Resonance Ruby. This creation stands out through its extraordinary natural ruby dial, sourced and crafted by a local Swiss stone artisan. The brand selected only genuine ruby exhibiting depth of colour, fine inclusions, and naturally occurring variations—features that are not flaws but signatures of authenticity, shaped by geological processes over millions of years. As light moves across the dial, subtle tonal shifts appear, infusing the watch with a vibrant mineral presence that contrasts strikingly with the symmetry and modernity of the exposed mechanics.

Beyond its visual impact, this edition embodies ARMIN STROM’s belief that materials must carry meaning. While natural ruby asserts its aesthetic and symbolic presence on the dial, synthetic ruby jewels within the movement fulfil their longstanding horological role of reducing friction and ensuring long-term precision. It is a thoughtful dialogue between nature and engineering, where raw mineral beauty coexists with technical necessity.

At the core of the watch lies the hand-finished Calibre ARF21, a manufacture movement entirely designed and produced in-house. Its defining feature is the brand’s patented Resonance Clutch Spring, which connects two independent regulating systems, enabling the balance wheels to oscillate in harmonic resonance. This phenomenon enhances chronometric stability and is visually showcased by a pusher at 2 o’clock that resets both seconds hands simultaneously—a dramatic demonstration of mechanical synchronicity in action. Operating at 3.5 Hz (25,200 vph) and offering a 48-hour power reserve, the movement transforms a centuries-old scientific principle into contemporary watchmaking mastery.

Craftsmanship remains central to ARMIN STROM’s ethos. The bridges feature hand-polished bevels, black-polished screws, perlage, and circular graining, with Geneva stripes enriching the reverse side. As with every ARMIN STROM timepiece, each watch is assembled twice, ensuring absolute performance and finishing quality. This meticulous approach, combined with the vibrant ruby dial, creates a visually dynamic composition—a living interplay between stone, metal, and motion.

Encased in a 43 mm stainless steel case and fitted with a grey Alcantara strap featuring white stitching, the Mirrored Force Resonance Ruby delivers both presence and refinement. It is not merely a new dial variation, but an artistic expression grounded in horological integrity—an encounter between natural geology and mechanical resonance, distilled into a timepiece of exceptional character.

Arnold & Son unveils the final chapter of its Constant Force 11 collection with the Constant Force Tourbillon 11 Platinum Edition, a limited series of just 11 pieces. This exceptional timepiece celebrates 260 years of horological heritage, paying homage to the legendary friendship between John Arnold and Abraham-Louis Breguet.

Crafted in platinum (Pt950), the 41.5 mm case houses a dial of hand-guilloché tremblé engraving in 18K yellow gold, inspired by the fern-covered moors of Tintagel, Cornwall—Arnold’s birthplace and the mythical land of King Arthur. The white opal subdial and visible constant force mechanism add depth and elegance.

Powered by the A&S5219 manual winding calibre, the watch features a constant force mechanism, one-minute tourbillon, and true-beat seconds. The engraved plate reads: "To the revered memory of John Arnold and Abraham-Louis Breguet. Friends in their time, legendary watchmakers always."

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."
