Armin Strom / One Week

Armin Strom One Week

Collection profile · 2023

Armin Strom’s One Week is the System 78 family’s seven-day, manually wound platform: a contemporary, openworked three-hander built around twin barrels, a prominent power-reserve display, and the brand’s accessible-haute-horlogerie positioning within its in-house collection architecture.

Why it matters

The One Week matters because it repackages Armin Strom’s foundational long-power manual calibre into a more wearable, modern System 78 format, making the brand’s architectural movement language and hand-finished mechanics available below its resonance-heavy flagship tier.
