Armin Strom Introduces New Mirrored Force Resonance in Green

The first iteration of the Armin Strom Mirrored Force Resonance was released in 2016. Since then, it has seen multiple variations. Following in the footsteps of the blue model released in February this year, Armin Strom has just unveiled the Mirrored Force Resonance in Green. Like the blue variant, the latest offering is also limited to 50 pieces.

The collection can be said as one of the finest in watchmaking because of its staging of the balance wheels on the dial, which is more of a 17th century concept being implemented in the 21st century. The concept refers to “resonance” in the context of timekeeping. Simply put, it involves housing two movements in a single case to ensure resonance so that the two balance wheels of the movements can be synchronised. This kind of synchronised motion has fascinated horologists since the mid-seventeenth century when Dutch scientist Christiaan Huygens famously studied the resonance of two different pendulum clocks.

In 2016, Armin Strom offered its unique take on the concept. It launched the Mirrored Force Resonance watch with two separate balance springs that were connected by a resonance clutch spring that brought two separate hands together in almost perfect synchronisation. It took Armin Strom more than two years to create this movement.

Carrying forward the practice of creating timepieces with minute changes, the new Mirrored Force Resonance (Ref. ST22-RF.20) in Green watch gets the same 43 mm stainless steel case as its predecessor. The lugs are shorter than what one would normally expect on a timepiece with such dimensions. The layout is the same as that seen on the 2022 model and the one released in February. It’s just that the time indications are now enhanced in green. The off-centred green dial at 3 o’clock gets skeleton steel hands for the hour, and minute hands are decorated with grenage in the centre with applied hour markers and a satin-brushed chapter ring.

The two resonance counters intersect the dial, relaying the seconds and rotating in opposite directions. Both seconds dials feature green rings with white numerals. The dual seconds dials can be reset with a pusher at 2 o’clock. The dial also has two balance wheels on the left side with openworked bridges. In between the two oscillating dials lies the Armin Strom patented resonance clutch spring, connecting the two balance wheels. 

Powering the model is the same in-house ARF21 automatic movement that ran the 2022 and the February 2023 variants, offering 48 hours of power reserve. Turning the watch over showcases the manual-winding movement with open bridges and ‘out of 50’ engraving. Finishing the watch is a grey Alcantara strap with white stitching and a double-folding clasp in stainless steel.
