Armin Strom Gravity Equal Force

The new Gravity Equal Force is the newest timepiece from Armin Strom. This watch is not only demonstrating continuous innovation, one of the core principles of the manufacture, but also takes the traditional mainspring barrel and turns it on its head. The Gravity Equal Force also marks the launch of the new System 78 Collection, highlighting innovative watchmaking at a competitive price.

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 barrell to limit the torque delivered to the balance, providing a smooth 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, which contained a motor barrel design showing clear advantages over the standard going barrel. So the watchmakers designed a barrel operating in the reverse of a traditional mainspring barrel driving the gong train via the barrel arbor and winding the barrel housing.
All of this is built into the new ASB19 calibre which works at a frequency of 3 Hz and provides a power reserve of up to 72 hours.

The new Gravity Equal Force also differs from previous models with a new off-center dial and slimmer case with a smaller diameter. The highlight of the watch is now the triplet of bridges. Moving to an off-center dial, the Gravity Equal Force is more legible to maximize the user experience.
The 41-mm-case is a first for Armin Strom. It is shaping a new aesthetic that showcases the reduction to the essential while maintaining the essence of the manufacture’s DNA.
