Introducing the Armin Strom Gravity Equal Force Ultimate Sapphire Blue

JUNE 25 2025    |    Novelties

We are thrilled to announce the launch of the Armin Strom Gravity Equal Force Ultimate Sapphire Blue, a masterpiece of Swiss horology that combines technical innovation with glacial elegance.

Design & Aesthetics

The watch features a 41 mm stainless steel case and an off-center transparent sapphire crystal dial with a subdial. The main plate, crafted by Kari Voutilainen, showcases a stunning glacial blue guilloché pattern. The color palette of silvery greys and soft blues is inspired by the serene beauty of Swiss glacial lakes. The watch is completed with a blue nubuck leather strap with ice blue stitching.

Movement & Mechanics

Powered by the proprietary Caliber ASB19, the Gravity Equal Force Ultimate Sapphire Blue is the world’s first automatic movement with a patented stop-work declutch mechanism and Geneva cross. This ensures consistent torque and precision across a 72-hour power reserve. The movement is visible through both the front and back sapphire crystals, and features hand-finished components with perlage, Geneva stripes, and circular graining.

Craftsmanship

Each watch is assembled twice to ensure reliability and refinement. Every component is hand-finished in Biel/Bienne, emphasizing traditional techniques and an open-worked design.

Brand Philosophy

Armin Strom celebrates Swiss horological tradition and innovation. Founded in 1967 and revitalized in 2009 by Claude Greisler and Serge Michel, the brand is known for exposing movement mechanics on the dial side. Their motto, “The Science of Movement,” reflects their dedication to precision and craftsmanship.

Limited Edition

The Gravity Equal Force Ultimate Sapphire Blue is limited to just 25 pieces per year, making it a truly exclusive timepiece.

To mark the 16th anniversary of the manufactory, Moritz Grossmann presents the limited-edition ENAMEL ROMAN Vintage

Black is the absence of light. This is the physical definition of a colour that is synonymous with classicism and elegance. At Moritz Grossmann, black is used to form stylish contrasts and also serves as a testament to the highest standards of craftsmanship. The limited-edition ENAMEL ROMAN Vintage, for example, has an enamel dial whose manufacture presents multiple challenges. With this, Moritz Grossmann has chosen the occasion of its 16th birthday to once again shine the spotlight on the expertise of the ateliers and workshops in Glashütte.

Tradition requires renewal, otherwise it remains stagnant in the past and cannot survive. This is an approach that Moritz Grossmann has embodied since 2008: the manufactory opened 16 years ago as a tribute to one of the most exceptional personalities in the history of watchmaking in Glashütte. Moritz Grossmann was an innovative watchmaker and, with the founding of the German Watchmaking School in Glashütte, influenced a generation of artisans.

His values and vision now live on in the Moritz Grossmann manufactory, which crafts a small but exquisite collection of sophisticated watches that always remain true to the standards of the man who gave the manufactory its name. Characteristics of these timepieces include exclusive manufactory movements with innovative details that are designed, made and finely decorated in-house in the company’s own workshops. The highest of standards also come into play when finishing the watches, as impressively demonstrated by the special model marking the 16th anniversary of the manufactory.

Moritz Grossmann GMT Guilloche Limited Edition Dual Time Zone Watch with Hand-Guilloché Dial

The Moritz Grossmann GMT Guilloche is a celebration of global exploration and fine German watchmaking. Inspired by the colors of nature and the rhythm of travel, this dual time zone watch is available in two striking dial variants: matte green, evoking serene meadows and hidden coves, and vibrant orange, reminiscent of the glow of a setting sun.

Dual Time Functionality

Designed for the modern traveler, the GMT Guilloche features a 24-hour time zone ring encircling the dial. A distinctive arrow-shaped hand tracks a second time zone, offering intuitive day-night orientation. Local time is displayed via central hour and minute hands, with a small seconds subdial at 6 o’clock. A dedicated crown at 10 o’clock allows seamless adjustment of the second time zone without affecting the main time.

Masterful Craftsmanship

Each dial is hand-engraved using the traditional guilloché technique, creating intricate geometric patterns that shimmer with light. The green dial is paired with blued steel hands, while the orange dial features polished steel hands—both handcrafted in Glashütte.

Engineered for Precision

Inside the watch beats the calibre 100.8, a manually wound movement crafted in-house and regulated in five positions. It features 253 components, 26 jewels, and signature Grossmann innovations including the 2/3 plate with raised gold chatons, cantilevered balance cock with micrometer screw, and a separately removable winding mechanism. The second time zone mechanism is seamlessly integrated on the dial side, ensuring precision and harmony.

Limited Edition

Encased in stainless steel and fitted with a hand-stitched black alligator leather strap, each GMT Guilloche model is strictly limited to 8 pieces worldwide, making it a rare collector’s item.

Discover the Art of Glashütte

Moritz Grossmann continues to honor its founder’s legacy by blending traditional craftsmanship with modern innovation. The GMT Guilloche is a wearable work of art—an invitation to wear the world on your wrist.

Greubel Forsey Unveils the Final Balancier Contemporain in Stainless Steel - A Defining Final Edition

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.
