The newest addition watch, the Gravity Equal Force continues to demonstrate a core principle of Armin Strom: always be innovating. This watch takes the traditional mainspring barrel and flips it on its head with the addition of stop-work declutch mechanism united with automatic winding to create consistent power delivery to the balance. With a powerful redesign of the movement, case, and dial, a new era is marked with the launch of the new System 78 collection with the Gravity Equal Force for the manufacture.

Every watch released from their manufacture must include an innovation, as a guiding principle for Armin Strom. Behind the inspiration of Gravity Equal Force was a need to transmit equal force to the balance. By achieving this they have increased 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 demonstrates the first time a stop-works declutch mechanism has been added to an automatic winding movement.

Never satisfied with merely one innovation, Armin Strom found inspiration in a pocket watch from a U.S. collector that was in need of repair. Motivated by this, the watchmakers created a barrel operating in the opposite direction of a traditional mainspring barrel by driving the going train via the barrel arbor & winding the barrel housing, thus improving both functionality and reducing wear.

This revolutionary design creates a stable, low-friction axis of rotation for the mainspring to deliver power from the barrel arbor, supported by precision jewel bearings. Though utilising only a portion of the mainspring by preventing it from completely unwinding, Armin Strom still achieved a 72 hour power reserve. The mainspring bears a power reserve indicator on the barrel for reference, wound by a unidirectionally winding micro rotor seen from the dial.

The new caliber ASB19 exhibits Armin Strom's commitment to continually question existing theory and using in-house R&D to advance horological technology as evidenced with numerous small improvement to the going train and winding mechanism. The more classically-inclined collector should appreciate the 41-millimeter case, a first for Armin Strom. The essence of Armin Strom's DNA is maintained through the contemporary dimensions while shaping a new aesthetic that showcases a reduction to the essential. By moving to an off-center dial, the Gravity Equal Force is more legible to maximize the user experience for discerning collectors.
