Features

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.
