Greubel Forsey GMT Balancier Convexe

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 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.

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.
