Independent Swiss watchmaker Armin Strom proudly presents the Gravity Equal Force Ultimate Sapphire Rose Gold, a timepiece that exemplifies the brand’s commitment to horological innovation, artisanal craftsmanship, and visual harmony.

Encased in 18K rose gold, this limited-edition watch features a sculptural movement architecture that plays with tone and texture. A brown guilloché mainplate, rose gold-colored bridges, and a floating off-centre sapphire dial create a refined and coherent composition. The watch is paired with a matte brown nubuck leather strap, adding an earthy elegance to the overall aesthetic.

At the heart of the timepiece is the Caliber ASB19, Armin Strom’s groundbreaking automatic movement. It incorporates a patented stop-work declutch mechanism and Geneva cross within the barrel, ensuring consistent torque delivery throughout its 72-hour power reserve. A micro-rotor enables efficient winding while preserving the symmetry and visibility of the movement — a hallmark of Armin Strom’s design philosophy.

Every component, visible or hidden, is hand-finished to haute horology standards. Techniques such as beveling, straight-graining, perlage, Geneva stripes, and black-polished screws are applied with precision and care. The mainplate features a “grain d’orge” guilloché pattern, crafted by master artisan Kari Voutilainen using a traditional hand-operated machine.

This exceptional timepiece is limited to just 25 pieces per year, making it a rare and radiant statement in the world of independent watchmaking. It is a testament to Armin Strom’s philosophy: Mechanics First. Always.

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."

Chronoswiss is proud to unveil the Delphis Glacier, a sophisticated interpretation of eternal ice and glacial beauty. Crafted in lightweight titanium and paired with a sleek black rubber strap, this latest addition to the Delphis family merges understated elegance with the bold mechanical spirit of Chronoswiss. Frozen landscapes meet modern horology. The Delphis Glacier is housed in a 42mm Grade 5 titanium case, whose natural metallic finish reflects the quiet strength and purity of alpine glaciers. Combined with the black rubber strap, the watch achieves a refined and contemporary presence on the wrist, evoking the calm majesty of ice formations shaped over centuries by nature itself.

Mechanical Cool
At the heart of the Delphis Glacier lies an upper dial that creates the stage for the retrograde minute and jumping hour complication. The crescent is silver galvanic and features a curved hand-guillochéd surface inspired by the delicate textures of glacial ice and frozen landscapes. The subdial, a curved UFO, holds the small seconds and is finished with a blue CVD-coating with hand-guilloché craftsmanship executed inside the Atelier Lucerne. The monochromatic interplay of textures and tones creates a sophisticated composition that feels both timeless and unmistakably modern.

The Soul of Precision
The Delphis Glacier is powered by the manufacture movement C.6004, a testament to Chronoswiss dedication to precision and innovation. Beyond its visual elegance, the movement ensures outstanding functionality and reliability, transforming the Delphis Glacier into a mechanical sculpture inspired by the silent power of nature. Every detail reflects the serene beauty and resilience of Swiss glaciers. As an homage to the enduring beauty and the purity of ice, the Delphis Glacier is produced in a limited edition of only 50 pieces, making it a rare companion for collectors seeking refined modern mechanics. Discover the silence. Embrace the glacier.

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.
