Gravity Equal Force Ultimate Sapphire Salmon

The Gravity Equal Force Ultimate Sapphire Salmon introduces a new chromatic expression to Armin Strom’s most celebrated movement. Housed in a compact 41mm stainless steel case, this edition is defined by its salmon-coloured PVD mainplate, visible through a grey-toned sapphire dial that draws the eye directly into the mechanics.

At its core beats the Calibre ASB19, the world’s first automatic movement to combine a micro-rotor with a patented equal-force barrel and stop-work declutch mechanism. This innovation ensures constant torque delivery to the balance throughout the full 72-hour power reserve, enhancing precision and isochronism.

Hand-finished in Biel/Bienne to the highest standards, the movement features polished and bevelled bridges, black-polished screws, Geneva stripes, circular graining, and perlage. The salmon mainplate is further elevated by an intricate hand-guilloché pattern executed in collaboration with Kari Voutilainen.

Produced in a limited annual series of 25 pieces, the Gravity Equal Force Ultimate Sapphire Salmon embodies Armin Strom’s philosophy of transparency, mechanical innovation, and uncompromising craftsmanship.
