Gravity Equal Force Ultimate Sapphire Anthracite

The Armin Strom Gravity Equal Force Ultimate Sapphire Anthracite is engineered around a 41 mm stainless‑steel case with a height of 12.65 mm, showcasing the brand’s signature open‑worked architecture and a grey‑toned off‑centre sapphire dial. The anthracite PVD mainplate features a hand‑executed guilloché pattern by Kari Voutilainen, adding depth and refinement to the exposed mechanism. Powering the watch is Armin Strom’s in‑house calibre ASB19, an automatic movement operating at 3.5 Hz and equipped with a micro‑rotor and the brand’s patented Equal Force barrel system, delivering a consistent torque output and a 72‑hour power reserve. The movement comprises 202 components and is finished to haute‑horlogerie standards, including Geneva stripes, circular graining, hand‑bevelled bridges, and a balance wheel with four regulating screws. The watch is fitted with a grey nubuck strap with matching grey stitching and keepers, completing the contemporary technical aesthetic. Produced as a limited edition of just 25 pieces per year, this model reflects Armin Strom’s commitment to precision engineering and artisanal Swiss manufacturing.
