Armin Strom Gravity Equal Force Ultimate Sapphire Salmon | LE25 |

Armin Strom reimagines its signature constant-force architecture with the Gravity Equal Force Ultimate Sapphire Salmon, a standout example of modern independent Swiss watchmaking. The openworked design reveals a salmon-toned PVD-coated mainplate beneath a transparent sapphire dial, creating immediate visual depth and mechanical intrigue. Framed by a 41mm stainless steel case, this luxury sports watch is paired with a grey nubuck leather strap, reinforcing its contemporary yet understated presence. Part of the System 78 collection, it reflects Armin Strom’s technical independence, in-house engineering, and forward-thinking design language. A limited edition of 25 pieces. Ref. ST24-GEF.SAL At its core is the manufacture Calibre ASB19, a micro-rotor automatic movement featuring a patented stop-work declutch mechanism inside the barrel. This innovation delivers constant force to the balance wheel across the full 72-hour power reserve, enhancing chronometric stability and long-term precision. The micro-rotor construction maintains a slim profile while allowing full visibility of the movement from both sides. Hand-finished in Biel/Bienne, the movement showcases polished bevels, black-polished screws, Geneva stripes, perlage, and a hand-guilloché salmon mainplate developed with Kari Voutilainen. Produced in a limited run of just 25 pieces per year, the Gravity Equal Force Ultimate Sapphire Salmon stands as a collectible expression of haute horlogerie, mechanical transparency, and artisanal finishing.
