Armin Strom Gravity Equal Force Ultimate Sapphire Blue | LE25 | Pre-Order
The Armin Strom Gravity Equal Force Ultimate Sapphire Blue is a striking evolution of the brand’s groundbreaking design, presented in a cooler, refined palette. Housed in a 41 mm stainless steel case, this limited edition timepiece features a Kari Voutilainen crafted glacial blue guilloché mainplate, set beneath a transparent sapphire dial. Positioned asymmetrically, the open-work design reveals the intricate inner mechanics of the watch, including the micro-rotor, equal-force barrel, and rhodium-finished finger bridges. The shimmering silver and icy blue tones offer a sleek contrast, while the matching blue nubuck leather strap completes the streamlined aesthetic.

At the heart of the watch is Armin Strom’s proprietary Caliber ASB19, the first automatic movement to incorporate a stop-work declutch mechanism with a Geneva cross in the barrel. This patented system ensures constant torque delivery to the balance wheel, optimizing precision and improving isochronism throughout its impressive 72-hour power reserve. The movement remains elegantly slim, thanks to its efficient micro-rotor design, and is fully visible through front and back sapphire crystals—showcasing the seamless blend of technical innovation and horological artistry.
Every component of the Gravity Equal Force Ultimate Sapphire Blue is hand-finished in Armin Strom’s atelier in Biel. From bevelled and polished bridges to black-polished screws and decorative techniques such as Geneva stripes, perlage and circular graining, every detail reflects the brand’s dedication to craft. Each piece is assembled twice to guarantee exceptional quality and long-term reliability. Produced in an annual limited series of just 25 pieces, this watch represents a rare opportunity to own a truly modern expression of Swiss watchmaking excellence.
