Armin Strom has announced a new color variation of the "Mirrored Force Resonance" watch, the "Mirrored Force Resonance Red." This model combines a vibrant, offset red guilloché dial with the resonance mechanism and will be limited to only 15 pieces worldwide.

A new color variation of the "Mirrored Force Resonance" has been released. Featuring a vibrant red dial, only 15 pieces will be sold worldwide. Manual winding (Cal. ARF21). 39 jewels. 25,200 vibrations/hour. Power reserve of approximately 48 hours. Stainless steel case (43mm diameter, 11.55mm thickness). 3 ATM water resistance. Limited to 15 pieces worldwide. Estimated price: 17,600,000 yen (including tax).
What immediately catches the eye is the red guilloché dial, crafted using a traditional manual rose engine lathe. The pattern radiating from the center offers a delightful interplay of light and shadow. A black azure-finished chapter ring surrounds the dial, adding contrast to the overall design. Faceted hour markers are positioned to appear as if floating above the guilloché decoration, enhancing both depth and legibility.
The 43mm diameter case is made of stainless steel. It is paired with a gray Alcantara strap, giving it a soft and elegant look.


The movement used is the Cal.ARF21, designed, developed, and manufactured in-house. It integrates two completely independent movements within a single caliber, each containing its own mainspring, gear train, escapement, and regulating mechanism. A patented resonance clutch maintains a state of harmonious resonance between the two balance wheels. This enhances accuracy stability and enables a stable rate over long periods. Furthermore, by operating the pusher at the 2 o'clock position, both second hands can be reset to zero simultaneously, allowing for visual confirmation of the synchronization within the movement.
These mechanisms and traditional hand-finishing can be appreciated from both the front and back. Hand-polished bevels, frosted finishes, perlage, and circular grain finishes are used, along with black polished screws. Furthermore, the main plate on the reverse side features a three-dimensional relief inscription, expressing a unique visual identity. Like other models from the company, this piece is completed through a double-assembly process.
