Armin Strom One Week Skeleton Titanium TI25-OW-75

An ultralight, openworked masterpiece Now fully skeletonized, the Armin Strom One Week Titanium Skeleton is an openworked masterpiece that reveals the intricate heart of its mechanics while combining striking design with precision engineering. Encased in lightweight titanium grade 5, and retaining the confidence of 100 meters of water resistance, it balances strength with comfort, providing a feeling of lightness and capability that makes it easy to wear all week long. Armin Strom fans might remember that the inaugural One Week Manufacture Edition was already openworked by nature, but this titanium iteration goes even further, removing more material to highlight the movement’s complexity. Few watches combine openworking and skeletonization at this level. The small seconds dial is now skeletonized, revealing the power reserve level and the escapement wheel for a 3D mechanical animation. The mainplate and barrel bridges are also skeletonized enhancing aesthetics. Thanks to this skeletonization, the power reserve indicator is highlighted as well as the cone mechanism, reminiscent of ancient pocket watches. A major highlight is the case back, offering a mesmerizing view of the entire mechanism. The manual-winding ARM21 calibre visible throughout features two mainspring barrels which work in series to provide consistent levels of energy to the gear train. Held by two finger-style bridges, the barrels are symmetrically arranged and take up the right portion of the completely open dial. The 7-days power reserve is indicated by a cone system, inspired by pocket watches. With a 7-day power reserve, this watch keeps time accurate for an entire week without needing winding. The hand-finished details reflect the level of craftsmanship behind its design. Limited to 100 pieces, the One Week Titanium Skeleton offers a refined, functional timepiece that blends robustness and comfort in a minimalist package.
