Gravity Equal Force Ultimate Sapphire


The Gravity Equal Force Ultimate Sapphire is a new interpretation of an extremely popular and rare model by the Armin Strom brand. The exclusive watch features a monochrome colour scheme, an off-centre grey-tinted sapphire dial, a black hand-engraved plate, a hand-finished black guilloché movement plate by Kari Voutilainen, an off-centre grey-tinted sapphire crystal dial, and an ASB19 automatic calibre with a 72-hour power reserve.

CHF 22,900.-

The movement is equipped with a “stop-work” mechanism that prevents the main spring from fully unwinding, thus ensuring constant power transmission. The Gravity Equal Force Ultimate Sapphire was created in Armin Strom’s atelier in Biel.

The brand is known for assembling the movement used in a watch twice so that they can regulate and test it carefully – a complex process that was, of course, also used for the new Gravity Equal Force. The movement is housed in a classic 41-mm stainless steel case and is complemented by a black fabric strap with light grey decorative stitching.
