Armin Strom Gravity Equal Force Ultimate Sapphire Blue

Armin Strom introduces the Tribute 1 Green, a refined dress watch that pays homage to the timeless beauty of nature. Limited to just 50 pieces, this new release brings forest-inspired tones to the brand’s most elegant collection, combining artisanal craftsmanship with modern mechanical innovation.

A Forest-Inspired Masterpiece

The Tribute 1 Green features a striking off-centre dial in forest green, adorned with a hand-engraved grain d’orge guilloché pattern and crisp white Roman numerals. A frosted subdial adds depth and texture, while the green Alcantara leather strap with off-white stitching completes the composition with understated sophistication. The openworked motor barrel, secured by a polished finger bridge in stainless steel, echoes the case design and showcases Armin Strom’s signature fusion of symmetry and mechanical artistry. The 38 mm stainless steel case, with anti-reflective sapphire crystals front and back, ensures optimal clarity and elegance.

Exceptional Performance

At the heart of the Tribute 1 Green is the manual-winding Manufacture Caliber AMW21, offering an impressive 100-hour power reserve. This is made possible by the brand’s patented equal force barrel, designed for efficiency and compactness. Operating at 25,200 vibrations per hour (3.5 Hz), the movement reflects Armin Strom’s technical mastery, with 97% of components produced in-house.

Haute Horlogerie, Hand-Finished

Every Tribute 1 Green is a testament to traditional watchmaking. The case features brushed and polished surfaces, finished entirely by hand. Inside, the movement is decorated with Geneva stripes, circular graining, and a mirror-polished finger bridge, all executed by Armin Strom’s skilled artisans.

True to the brand’s commitment to excellence, each watch is assembled twice—once for mechanical precision and again after decoration—to ensure the highest standards of performance and aesthetics.

Greubel Forsey presents the final edition of the Balancier Contemporain, marking the definitive conclusion of this iconic calibre. This timepiece is housed in a 39.6mm stainless steel case – a material that has only been used twice before in the history of the Atelier. Limited to just 33 timepieces, this edition will be built and delivered exclusively in 2025. Once complete, the Balancier Contemporain calibre will be permanently retired and will never be made again.

More than a final edition, this stainless steel interpretation is a statement of purpose – it is the rarest and most exclusive case material in the Atelier’s repertoire. Its presence here is deliberate: to honour the legacy of the Balancier Contemporain with purity, restraint, and resolve.

Compact, Yet Monumental

When it was introduced, the Balancier Contemporain redefined expectations – delivering the full Greubel Forsey experience in just 39.6mm. This final edition preserves that feat of engineering and design. Under its high-domed sapphire crystal, the gold dial reveals a rich interplay of levels, textures, and finishes. A sunburst blue hour-ring frames the composition, while a deep blue minute-circle and sectorial indications for the small seconds and power reserve create both contrast and clarity. A large visual opening draws the eye to the in-house 12.6mm balance wheel, suspended above a flat, black-polished gold plate that provides visual depth and dramatic reflection.

The movement is composed of 256 parts, each hand-finished to the highest standard. The bridges are in nickel silver, frosted and spotted by hand, with perfectly polished bevels and countersinks, straight-grained flanks, and a subtle blue treatment unique to this edition. The balance wheel bridge is flat black polished steel – one of the most demanding finishes in haute horlogerie – with hand-polished bevels that reflect light beautifully. The balance wheel itself is mounted above a flat black-polished gold plate, a surface so refined it becomes both technical and architectural.

On the movement side, a black-polished gold plate is engraved in relief with the fundamental values of Greubel Forsey – invisible to the wearer, yet finished with the same uncompromising care. Olive-domed jewels are set in gold chatons, with hand-polished countersinks that catch the light at just the right angle. Every component, visible or not, is treated with the same reverence – as if each part could stand on its own as a miniature work of art.

A Closing Statement – and a New Beginning

This is the last timepiece to carry the Balancier Contemporain calibre – but it is also the first to signal a new direction. With this final edition, Greubel Forsey opens a new chapter focused on small-diameter timepieces. Over the coming years, this creative momentum will continue to build, exploring new dimensions of mechanical expression, proportion, and elegance – all without compromise.

The Balancier Contemporain in stainless steel is a definitive conclusion – and a confident beginning.

gérald genta continues its legacy of audacious elegance with the launch of two new references in the Gentissima Oursin collection: Blue Meteorite and Green Meteorite. These timepieces mark a bold evolution of the iconic design first imagined by Mr. Gérald Genta in 1994, inspired by the delicate yet resilient form of the sea urchin.

A Design Born from Nature and the Cosmos
The Gentissima Oursin 41 features a 41mm sandblasted Grade 5 titanium case, meticulously set with 234 white gold beads, echoing the organic geometry of the sea urchin. At its heart lies a dial carved from a fragment of meteorite—a material born from the stars—making each watch a unique, one-of-one creation. The natural crystalline structure of meteorite ensures that no two dials are alike, offering collectors a truly rare expression of artistry.

Sporty-Chic Meets Haute Horlogerie
Combining rubber straps and titanium architecture with luxurious gold accents, the Gentissima Oursin 41 is designed for everyday wearability without compromising sophistication. A curved sapphire crystal, faceted with a subtle octagonal profile, protects the dial and enhances its dynamic character. Gold hands filled with Super-LumiNova featuring a pink hue—a tribute to Mr. Genta’s favorite color—ensure legibility and elegance.

Mechanical Excellence
Inside beats the Zenith Elite GG-005 automatic movement, boasting a 50-hour power reserve, 4 Hz frequency, and an 18K yellow gold oscillating mass, visible through a sapphire caseback. With 50m water resistance and a comfortable rubber strap, this timepiece is as practical as it is artistic.

The watch features a star-shaped arrangement of seven bridges, radiating from the center like a nebula, giving it both structural integrity and visual depth.

The movement is laid out with four lines of symmetry, aligning the barrels, balance, and small seconds for a harmonious aesthetic.

Technical Excellence: A&S5201 Calibre

Dual barrels provide an impressive 90-hour power reserve.

Components are arranged in a kinematic chain around the edge, enhancing both function and form.

The crown mechanism is inverted and placed on the case-back side for symmetry with the first wheel at 9 o’clock.

Aesthetic Details

The lower levels of the movement are treated with a rich blue PVD, contrasted by palladium-finished bridges and components.

Includes horizontal satin brushing on the dial side and Arnold & Son’s signature ‘Rayons de la Gloire’ motif on the reverse.

The 40 mm diameter and 9.10 mm thickness ensure elegance on the wrist.

Strap & Bracelet Options

Available with a blue alligator leather or rubber strap.

Also offered with a three-link steel bracelet that highlights the watch’s symmetry and skeletonized beauty.

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."
