With the success of the premiere model in stainless steel, Armin Strom releases the Gravity Equal Force in a 18k rose gold case.
We covered the premiere model at launch with high resolution photography and hands-on details as follows:
Armin Strom Gravity Equal Force in 18k RG
In a nutshell: The new release model is now in an 18k rose gold case, with a striking black dial and rose gold cocks visible from the dial side. This is an attractive visual contrast. The movement remains unchanged from the premiere release and is the ASB19, which boasts of several interesting features – the Stop Works with De-clutch and the Motor Barrel.
The new watch comes at a CHF 10k premium over the SS model – CHF 26,900 in RG viz a viz CHF 16,900 in SS.

The black dial gives the remarkable timepiece an elegant retro character and highlights the new design of the watch with striking contrast.
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. With a bold redesign of the movement, dial and case, Gravity Equal Force marks the launch of the new System 78 Collection, highlighting innovative watchmaking at a competitive price.
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.
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 unidirectionally 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.”
The Armin Strom Gravity Equal Force is the first model of the new System 78 Collection. It features a 18ct rose gold case and is priced at CHF 26,900.
