Armin Strom Feel The Force

Armin Strom Feel The Force

We are great admirers of Armin Strom and their passion for skeletonised watches and love of creating innovative timepieces.

Gravity Equal Force is the newest watch demonstrating an Armin Strom core principle: always be innovating. This watch takes the traditional mainspring barrel and turns it on its head by adding a stop-work declutch mechanism combined with automatic winding to create consistent power delivery to the balance. 

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.

We have reinvented the whole functionality of an automatic watch movement to bring another level of precision and to offer our collectors more assurance for reliable daily wear.”
