Armin Strom One Week Manufacture Edition Blue | LE100

The Armin Strom One Week Manufacture Edition Blue delivers a modern expression of Armin Strom’s signature open-worked watchmaking, pairing technical depth with contemporary Swiss design. Housed in a 41 mm stainless steel case and finished with an integrated steel bracelet, this luxury sports watch offers a refined balance of comfort, durability, and architectural presence. The absence of a traditional dial places full focus on the deep blue PVD-coated main-plate, transforming the movement into the visual centerpiece. Bold contrasts, sculptural geometry, and exposed mechanics define this high-end mechanical watch, making it a standout among independent Swiss timepieces.

A limited edition of 100 pieces
Ref. ST23-OW.FE

At its core is the in-house manual-winding Calibre ARM21, developed, finished, and assembled entirely within the Armin Strom manufacture. A twin-barrel system delivers an impressive seven-day power reserve, while the 3.5 Hz frequency ensures stable, precise timekeeping. The three-dimensional conical power reserve indicator adds kinetic depth, referencing historical pocket watch engineering through modern execution. Hand-finished bridges, polished bevels, Geneva stripes, and circular graining reflect true haute horlogerie craftsmanship, with each movement assembled twice for uncompromising quality. Limited to just 100 pieces, the One Week Manufacture Edition Blue stands as a collectible Swiss luxury watch defined by mechanical transparency, innovation, and enduring performance.
