Angelus Flying Tourbillon Skeleton Titanium, Orange Edition

oritz Grossmann celebrates the 200th birthday of its founder with the launch of the TEFNUT 36 Silver-Plated by Friction Turquoise Blue, a timepiece limited to just 12 pieces worldwide. This special anniversary edition combines traditional 19th-century craftsmanship with a modern aesthetic, paying homage to the visionary watchmaker, scientist, and founder of the German Watchmaking School. The manufactory in Glashütte continues to honor this rich heritage by blending historical techniques with contemporary design.

The dial of the watch is crafted using a meticulous silver-plating by friction technique, also known as silver-plating by grit, which is executed entirely by hand through multiple complex steps involving silver powder, salt, tartar, and water. This traditional process imparts a velvety, matte structure with remarkable optical depth, further enhanced by a unique green-tinged blue hue that shifts dynamically depending on the angle and lighting. Contrasting the textured surface are engraved Roman numerals lacquered in blue, alongside the historic 1875 'M. Grossmann' logo, scale markers, and manually crafted steel hands annealed to a vibrant blue hue.

Housed in a slender and expressive 36-millimeter stainless steel case with a flat profile, the watch is designed to offer exceptional comfort and elegance on any wrist. It is complemented by a hand-stitched grey kudu leather strap featuring a pin buckle in stainless steel. Inside ticks the manufacture calibre 102.1, a hand-wound mechanical movement measuring just 3.45 millimeters in thickness, featuring a pillar movement architecture, a three-fifths plate, a stepped balance cock with a Grossmann micrometer screw, and a special '1826' anniversary engraving.

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.

Armin Strom, the independent Swiss watchmaker renowned for its openworked designs and mechanical innovation, proudly unveils two striking new additions to its System 78 collection: the Orbit Lime Green and Orbit Ice Blue.

These limited edition timepieces—each restricted to just 20 pieces worldwide—introduce vibrant new fumé dials that blend bold aesthetics with technical mastery. The Lime Green model radiates energy and modernity, while the Ice Blue version offers a serene and sophisticated presence. Both dials feature a gradient effect that transitions from vivid color at the center to deep black at the edges, enhancing the visual depth of the openworked design.

A World-First Date Display on Demand

At the heart of both models lies the Armin Strom Manufacture Caliber ASS20, the world’s first movement to feature a date display on a ceramic bezel that appears only when activated. A pusher at 10 o’clock engages the date hand, which points to the current date and advances automatically at midnight. A second press returns the hand to its neutral position, offering a playful yet practical complication powered by a column-wheel mechanism.

The movement also incorporates Armin Strom’s patented Equal Force Barrel, delivering consistent energy for a stable 72-hour power reserve.

Haute Horology Craftsmanship

Each Orbit model is meticulously hand-finished at Armin Strom’s Manufacture in Biel/Bienne, employing traditional techniques such as anglage, perlage, and circular graining. The off-center dial is paired with rhodium-coated hands enhanced with Super-LumiNova®, ensuring legibility and elegance. The watches are housed in a stainless steel case with a fixed ceramic bezel and come with a matching bracelet featuring a double-folding clasp.

The Science of Movement

Founded in 1967 and revitalized in 2009, Armin Strom continues to push the boundaries of horological innovation. Every timepiece is designed, developed, and assembled in-house, reflecting the brand’s commitment to transparency, craftsmanship, and mechanical excellence.

To celebrate 17 years since its rebirth in 2008, Moritz Grossmann unveils a horological milestone: the PERPETUAL CALENDAR. This grand complication embodies the brand's philosophy of timeless precision, combining traditional craftsmanship with modern innovation.

The PERPETUAL CALENDAR is engineered to automatically account for the varying lengths of months and leap years, requiring no manual correction until the year 2100. This makes it one of the most technically demanding and revered complications in fine watchmaking.

The dial is a study in symmetry and clarity. A full 1–31 date scale encircles the dial, with a cup-shaped indicator framing the current date. The month and weekday are displayed on subdials at 3 and 9 o'clock, decorated with Azurage finishing. Leap year and day/night indicators are integrated into the subdials. At 12 o'clock, a poetic moon phase display features a mother-of-pearl moon gliding across a goldstone sky.

At the heart of the watch is the newly developed Calibre 101.13, a hand-wound movement based on the 100.1 calibre with an added perpetual calendar module. It comprises 401 components — 211 for the calendar module and 190 for the base movement. The movement features optimised stopwork, an integrated manual winder, and an escape wheel bearing in the barrel bridge. The finishing adheres to traditional Glashütte standards, with untreated German silver plates, raised gold chatons, and hand-engraved details.

All calendar functions can be adjusted via recessed correctors on the case, operated with a dedicated tool. A sum corrector allows for quick synchronization of all indicators after periods of inactivity.

The PERPETUAL CALENDAR is available in three elegant variants: rose gold with argenté dial (Ref. MG-003906), rose gold with anthracite dial (Ref. MG-003907), and platinum with argenté/anthracite dial (Ref. MG-003904). Each model is paired with a hand-stitched dark brown alligator leather strap and a matching prong buckle.

Moritz Grossmann continues to honour its namesake's 19th-century legacy with a commitment to "Schönstes deutsches Handwerk" — the finest German craftsmanship. The PERPETUAL CALENDAR is a testament to this enduring vision, offering collectors a timepiece that is as poetic as it is precise.
