Gravity equal force

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.
