Armin Strom expands its Mirrored Force Resonance collection with a new 18K rose gold edition, marking the first time the brand’s signature case has been crafted from this metal. The 43 mm case features alternating brushed and polished finishes, framing a black off-centre dial with a handcrafted sunray guilloché pattern, created on a traditional rose engine lathe. Paired with a dark grey Alcantara strap, the piece blends refined aesthetics with technical mastery.

At its heart is the manually wound Caliber ARF21, a horological milestone that synchronises two balance wheels through Armin Strom’s patented Resonance Clutch, ensuring exceptional precision and stability. A pusher at 2 o’clock resets the dual seconds counters, offering a visual demonstration of the resonance effect in action.

The movement’s hand-finishing—including bevelled bridges, perlage, circular graining, and black-polished screws—can be admired through sapphire crystals on both sides. Each watch is assembled twice, guaranteeing mechanical and aesthetic perfection.

Co-founder and master watchmaker Claude Greisler described the new edition as “a significant milestone,” noting that the warm tones of rose gold complement the Mirrored Force Resonance’s technical sophistication and balance of tradition and innovation.
