In the Armin Strom Mirrored Force Resonance Zeitgeist 1665 3N, the mainplate and bridges are colored in 3N yellow gold, adding a classic touch to its contemporary architecture.
Against a black dial lacquered with poly-varnish, the gold takes center stage, while the deep black accentuates the architecture and intricate construction of the movement.
The stainless steel case has a diameter of 43 mm and a height of 11.55 mm, with a sapphire crystal case back with anti-reflective treatment. Limited to 25 pieces.
The heat-blued stainless steel hands, manufactured and finished by Armin Strom, add another distinctive element of traditional watchmaking. A 43 mm stainless steel case and a dark gray Alcantara strap complete the composition surrounding the yellow gold movement.
The idea behind the Zeitgeist is simple: to imagine what a resonant wristwatch might have been like centuries ago, if watchmakers had known then what we know now.
The sapphire crystal case back offers a view of the ARF21 caliber.
The in-house manufactured ARF21 caliber is based on an idea first explored in 1665, when Christiaan Huygens observed the synchronization of two pendulum clocks. Two independent regulating systems transmit their vibrations through the resonant clutch patented by Armin Strom, allowing the balance wheels to synchronize through the physical phenomenon of resonance.
Unlike historical attempts, the system is designed to maintain that synchronization on the wrist, improving chronometric stability under real-world conditions.
The caliber operates at 3.5 Hz (25,200 vibrations per hour) and offers an 80-hour power reserve thanks to two independent barrels. A double-seconds flyback mechanism allows both seconds hands to be reset simultaneously, adding a functional dimension to the visual symmetry of the two regulating organs.
Precision, Guided by Hand
The 3N-colored baseplate and bridges have a matte finish, creating a sober backdrop for the hand-beveled and polished edges and black-polished screws. Perlage and circular graining add further layers of traditional craftsmanship.
The skeletonized mainplate reveals the architecture surrounding the resonance mechanism, making it appear almost suspended within the movement. Traditional finishing techniques frame the mechanics without distracting from them.
And because finishing is meaningless without precision, each Armin Strom watch is assembled twice: once to check its functionality and again to ensure it functions perfectly.
