ARMIN STROM Gravity Equal Force Rose Gold
The Rose Gold model extends the impressive Gravity Equal Force collection with a striking contrast between its sophisticated, black dial and warm, rose gold case and triple bridges. The black dial gives the remarkable timepiece an elegant retro character and highlights the new design of the watch and its impressive movement. Gravity Equal Force conveys Armin Strom’s core principle of innovation at a competitive price.
Indeed, every watch created and manufactured by Armin Strom manufacture must include an innovation. As such, 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. With a bold redesign of the movement, dial and case, Gravity Equal Force marks the launch of the System 78 Collection and it represents the first time a stop-works declutch mechanism has been added to an automatic winding movement… innovative, right!
Not content with one innovation, Armin Strom found insight in a pocket watch 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.
This state-of-the-art 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 using only a portion of the mainspring by preventing it from completely unwinding, Armin Strom still achieved a power reserve of 72 hours. Wound by a unidirectional winding micro rotor visible from the dial, the mainspring bears a power reserve indicator on the barrel cover for reference.
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. Claude Greisler, co-founder of Armin Strom, highlights the improved usability: “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.”
Gravity Equal Force also differs from previous models due to its off-center dial and slimmer case with a smaller, 41mm diameter. The highlight of the watch is now the triplet of bridges echoing the pocket watch inspiration behind the ASB19. The contemporary dimensions maintain the essence of Armin Strom DNA while shaping a new aesthetic that showcases a reduction to the essential. Moving to an off-center dial, the Gravity Equal Force is more legible to maximize the user experience. Overall, its performance and design should appeal to the more classically-inclined collector with an appreciation for horological innovation.
The solid 18ct rose gold model is particularly attractive for those who appreciate fine case materials and a certain juxtaposition with contemporary design that retains both subtlety and classicism.
