Watch Description

The Gravity Equal Force is the world’s first automatic watch with constant force transmission. The result is consistent power delivery to the balance which ensures that the watch always delivers flawlessly constant precision.


As a demonstration of his commitment to the System 78 collection, co-founder and head-watchmaker Claude Greisler insisted on adding a stop-work declutch mechanism to an automatic winding movement for the very first time in horological history. The history of watchmaking has seen many solutions developed to address this problem, but none have ever been applied to a watch even remotely close in price to that of the Gravity Equal Force. In keeping with the mission of the System 78 collection to democratize access to haute horology timepieces, the extraordinary value proposition of this watch extends to the exceptional hand-finishing of its movement. The Gravity Equal Force fully embodies a core Armin Strom principle: to relentlessly innovate and thereby secure a new place in horological history with every timepiece that we develop, regardless of ultimate price point.


Building upon the classic stop-work mechanism architecture, Claude Greisler has developed an ingenious stop-work declutch system that operates inside the mainspring barrel to provide more consistent power delivery to the balance at every stage.
