Armin Strom Gravity Equal Force Ultimate Sapphire Purple
The Gravity Equal Force Ultimate Sapphire Purple from Armin Strom pushes the boundaries of contemporary watchmaking through a bold combination of technical innovation and striking visual design.
Defined by its vibrant purple-toned sapphire architecture, this edition showcases the Maison’s constant-force mechanism, a revolutionary system engineered to deliver more consistent energy throughout the movement’s power reserve. By optimising the non-linear force curve of a traditional mainspring, the Gravity Equal Force reinterprets one of watchmaking’s oldest mechanical challenges through advanced micro-engineering and independent craftsmanship.
Housed within a 41 mm stainless steel case, the open-worked construction reveals the intricate mechanics beneath, highlighting the precision, symmetry, and transparency that define the collection. Distinctive and highly contemporary, the Ultimate Sapphire Purple is a timepiece created for collectors who appreciate technical ingenuity expressed through bold horological design.

Movement, Handcrafted to Perfection
At Armin Strom, watchmaking begins with transformation rather than assembly. Within the Swiss manufacture in Biel, raw metal is reimagined into precision components through a carefully controlled sequence of operations. Every stage is executed in-house, ensuring complete mastery over both technical precision and aesthetic integrity, where advanced engineering and traditional craftsmanship operate side by side in perfect balance.
Once formed, each component is elevated through meticulous hand-finishing, turning functional parts into expressions of mechanical artistry. Angles are beveled, surfaces polished, and details refined to haute horlogerie standards before each movement is assembled twice to guarantee absolute precision. This disciplined process reflects a singular philosophy: to create transparent mechanics where every element is not only functional, but intentionally revealed.
