Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

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

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.

The tourbillon has long been regarded as one of the most fascinating complications in the history of watchmaking. Moritz Grossmann now reinterprets this horological icon with two extraordinary creations: TOURBILLON Titanium and TOURBILLON Tremblage. These timepieces embody the manufactory’s philosophy of blending traditional craftsmanship with contemporary aesthetics.

The TOURBILLON Titanium combines the technical sophistication of a flying three-minute tourbillon with the modern appeal of a titanium case. Its solid silver dial, adorned with a fine grain d’orge guilloche pattern, reflects the artistry of hand-guided engraving techniques. The result is a watch that is both lightweight and visually striking, offering a perfect balance of durability and elegance.

The TOURBILLON Tremblage, on the other hand, celebrates the beauty of historical handcraft. Its warm rose-toned dial is meticulously engraved using the traditional tremblage technique, creating a unique matte texture that softens light and enhances depth. Paired with a white gold case, this model exudes timeless sophistication while showcasing the manufactory’s dedication to artisanal excellence.

Both models are powered by the hand-wound calibre 103.0, featuring a flying three-minute tourbillon and patented innovations for precision timekeeping. Every component is finished by hand, from the engraved plates to the polished screws set in gold chatons, reflecting the highest standards of Glashütte watchmaking. These creations are more than timepieces—they are works of art that unite heritage and modernity in perfect harmony.

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.
