What is the Armin Strom One Week Skeleton Titanium?
Reference TI25-OW.75 is a titanium version of Armin Strom’s One Week design, presented at Watches and Wonders 2025. The brand describes it as a more fully skeletonized evolution of the line: the openworked dial side reveals more of the movement, while the sapphire caseback provides another view of its construction. Monochrome’s launch-era first look includes video coverage of the watch.
The design keeps a black minute ring and a skeletonized small-seconds dial. The indexes are filled with Super-LumiNova, as are the faceted, polished rhodium hands. A conical power-reserve mechanism is also exposed as part of the movement display.
Movement and seven-day power reserve
Armin Strom’s 2025 press release specifies the manually wound manufacture calibre ARM21-S, with a stated seven-day power reserve. Its conical power-reserve mechanism indicates the remaining reserve. The movement has a balance wheel with four regulating screws and measures 36.60 × 6.00 mm.
