Channelling a bold redesign of the movement, dial and case, the Gravity Equal Force signals the launch of the System 78 collection of innovative timepieces at competitive price points.

As a guiding principle, every watch that comes from the Armin Strom manufacture must include an innovation. The inspiration behind Gravity Equal Force was a desire to transmit equal force to the balance, thereby increasing the consistency of rate. Building upon the classic stop-works mechanism, Armin Strom developed an ingenious stop-works declutch system that operates inside the mainspring barrel to limit the torque delivered to the balance, providing smooth power delivery. This represents the first time a stop-works declutch mechanism has been added to an automatic winding movement.

Not content with one innovation, Armin Strom found insight in a pocket watch in need of repair from a U.S. collector, which contained a motor barrel design showing clear advantages over the standard going barrel. Inspired, the watchmakers designed a barrel operating in the reverse of a traditional mainspring barrel by driving the going train via the barrel arbor and winding the barrel housing, which both improves functionality and reduces wear. With numerous small improvements to the going train and winding mechanism, the new Caliber ASB19 demonstrates Armin Strom’s commitment to continually questioning established theory and using in-house R&D to advance horological technology.
