A classy three-hander with a sophisticated movement design and a cool mainspring technology.
Armin Strom Gravity Equal Force
After releasing several super-complicated timepieces like the Mirrored Force Resonance and the Masterpiece 2 Minute Repeater Resonance, the independent brand takes a serious step towards the everyday-watch territory. Fear not, the trademark design codes and the top-tier technology are still present, the overall concept has just become more wearable and suitable for real life. The attitude changes that Gravity Equal Force brings to the table are obvious, starting from the brand’s first 41-millimeter case produced in steel. The blue off-center time register as well as small seconds fitting in its circumference are visually counterweighted by the three massive and extremely stylish bridges of the openworked movement to the right.
The ASB19 automatic in-house caliber featuring an interesting stop-work declutch mechanism
The Armin Strom Gravity Equal Force is powered by the ASB19 automatic in-house caliber beating at 3,5 Hz. The main trick here is clearly the unconventional barrel / mainspring usage. Instead of going the fully-wound / totally empty path, it features a stop-work declutch mechanism combined with automatic winding to create consistent power delivery to the balance. In other words, the watch tends to utilize only the middle part of the mainspring providing the optimal torque. Still, the power reserve here is quite impressive 72 hours. The piece comes on a matching alligator strap and commands a price of CHF 16,900.
