Armin Strom enters a new chapter in its horological narrative with the Mirrored Force Resonance Rose Gold, a piece which brims with mechanical ingenuity and artistic refinement. Presented under embargo until August 2025, this edition tastefully unites traditional Swiss-German craftsmanship—a hallmark of Biel/Bienne’s watchmaking culture—with the distinctive innovation that has become Armin Strom’s calling card since its revitalisation in 2009.
The presentation of the dial is unapologetically bold, anchored by a striking black guilloché finish achieved on a traditional rose engine lathe. This off-centre display, framed by a chapter ring with a circular texture, creates a compelling interplay of light and depth. The sunray motif radiates with exceptional sharpness, confidently setting the stage for the polished baton indexes and rose gold coloured, facetted and polished hands, providing exceptional legibility without diminishing the watch’s visual drama.
The guilloché technique imparts a tactile allure, inviting a closer examination of both its artistry and Armin Strom’s technical flair. There is an undeniable sense of organic evolution, from the swirling textures of the dial to the sculpted form of the time indicies, harmoniously contrasted by the deep, dark backdrop.
At the heart of this gold-clad marvel lies the manually wound Calibre ARF21, arguably one of the most intriguing technical achievements in contemporary horology. The movement’s dual oscillator construction, joined by Armin Strom’s patented resonance clutch, operates at a frequency of 3.5Hz, equivalent to 25,200 vibrations per hour. Through the sapphire crystal, the intricate hand-finishing is immediately apparent: bridges are expertly bevelled by hand, surfaces alternate between mat finishes and classical polishing, and black-polished screws punctuate the movement’s architecture. The execution of perlage and circular graining adds yet another layer of nuance, reflecting the manufacture’s unwavering commitment to craft and mechanical aesthetics. Notably, the movement is assembled twice, a practice that reaffirms Armin Strom’s focus on both mechanical and decorative exactitude. Twin seconds counters, resettable via a pusher at two o’clock, allow the wearer to witness the ongoing synchronisation of the two balance wheels, an elegant demonstration of resonance in action. With a 48-hour power reserve and a total of 276 components, the ARF21 movement is both an intellectual and sensorial delight, manifesting the brand’s philosophy in tangible form.
The case, now for the first time sculpted from 18K rose gold, evokes an undeniable sense of opulence while maintaining Armin Strom’s industrial, modernist spirit. Measuring 43mm in diameter and 11.55mm in height, with a lug-to-lug distance of 49.60mm, the case alternates between brushed and polished surfaces. The design does not pander to excess; instead, it exudes quiet assurance, with sapphire crystal and case back treated with anti-reflective coating for an unimpeded view of the movement. The warmth of the rose gold interacts beautifully with the darker dial, echoed again in the deep grey Alcantara strap. The choice of a gold pin buckle, matching the case, underlines the harmonious material palette and attention to proportionality.
In conclusion, this new iteration of the Mirrored Force Resonance is not simply a change of metal, but a considered celebration of tradition, mechanical innovation, and tactile and visual richness. The use of 18K rose gold signals a meaningful progression for the series, offering collectors a new modality to experience Armin Strom’s iconic resonance mechanism, a harmony of technical depth and aesthetic balance, with only 15 pieces to be created. As Claude Greisler, Co-Founder and Master Watchmaker expresses, this edition captures a harmonious blend of tradition and modernity, the golden era indeed.
