Description
Armin Strom One Week Manufacture Edition Blue
Ref: ST25-OW.05
A bold reinterpretation of Armin Strom’s first in-house calibre, the One Week Manufacture Edition Blue stands as a striking statement of mechanical artistry. Framed in stainless steel and finished with a sculptural openworked structure, the timepiece reveals the deep blue PVD-coated mainplate that forms the visual centrepiece of its architecture. The absence of a traditional dial draws the eye into the depth of its movement, where each detail is shaped by precision and performance.
Encased in a 41 mm stainless steel case and fitted with an integrated bracelet, the One Week Manufacture Edition Blue embodies refined ergonomics and a cohesive design language. Contrasts of polished and satin-brushed surfaces highlight its geometry, while the deep hue of the movement provides a captivating play of light and depth. The result is a contemporary expression of traditional watchmaking infused with unmistakable Armin Strom character.
At its heart beats the in-house Calibre ARM21 – a manual-winding movement fully developed, manufactured, decorated, and assembled by Armin Strom’s watchmakers in Biel. Twin barrels mounted in series provide an impressive seven-day power reserve, while the balance operates at 3.5 Hz for enhanced chronometric stability. A signature feature, the three-dimensional power reserve indicator, employs a conical gear and polished cone reminiscent of vintage pocket watches, adding dynamic motion to the display.
Each component of the ARM21 is meticulously finished by hand. Straight and circular graining, polished bevels, Geneva stripes, and blued screws exemplify the mastery of traditional Swiss craftsmanship. Every movement undergoes a double assembly process, a hallmark of Armin Strom’s uncompromising quality control, ensuring precision in both performance and aesthetics.
Limited to just 100 pieces worldwide, the One Week Manufacture Edition Blue continues Armin Strom’s legacy of innovation and integrity in independent watchmaking. It is a modern expression of endurance, artistry, and balance – a timepiece made not only to measure time but to celebrate it.
