Armin Strom expands its Mirrored Force Resonance offerings with a new model sporting a stunning green grenage dial.
Nicely matched with a grey synthetic suede ‘Alcantara’ strap, this limited edition (of fifty pieces) again highlights the independent watchmaker’s unusual resonance-based in-house movement that teams two balance wheels linked to create heightened chronometric precision and consistency.
The key to Armin Strom’s mastery of resonance in a wristwatch is the Armin Strom Resonance Clutch Spring, a tuning-fork-shaped metallic spring first seen in the 2016 Armin Strom Mirrored Force Resonance.
Set between the two oscillators on the left side of the dial, the Clutch Spring synchronizes the two movements as they keep time for the offset green dials.
Resonance, a technically difficult and hard to regulate technique used by only a few other watchmakers, essentially means the two movements become synchronized as they operate.
This creates a highly stable timekeeping rate that heightens the watch’s overall precision. When two movements resonate, overall operating efficiency improves while the potential of shock-inflicted error diminishes.
Admin Strom explains that it was inspired to create the new frosted green hue by some vintage equipment at its atelier.
“We chose this green because it harmonizes with the polished and decorated parts of the open-worked movement,” says Armin Strom’s Master Watchmaker and co-founder, Claude Greisler. “And the grenage finish gives a contrast to the polished indexes. This frizzy, kind of frosted surface reflects some light – but it is not too loud. It doesn’t overwhelm your attention and it shouldn’t compete with the movement.”
All the components within the 43mm steel watch are hand-polished. The dial side surfaces are also hand-finished with frosted, perlaged or circular-grained finishes. Armin Strom also assembled its movements twice “to ensure an uncompromising commitment to quality.”
