Armin Strom Gravity Equal Force Ultimate Sapphire ST21-GEF.SA.VE.L.35.FC

Since its establishment in 2009 in Biel, Switzerland, this independent watch brand combines traditional Swiss-German craftsmanship with innovative, self-developed movements. Under the leadership of watch enthusiast Serge Michel and master watchmaker Claude Greisler, the brand is known for its distinctive open-worked design style, also referred to as 'transparent mechanics.' Each watch is handcrafted, with almost all components of the movement produced in-house. This dedication keeps production intentionally limited, contributing to the exclusivity of each model. Today, the brand is considered one of the leading independent watchmakers in Switzerland – beloved by collectors and connoisseurs worldwide for the exceptional quality and craftsmanship in every detail. The Gravity Equal Force Ultimate Sapphire combines technical innovation with striking design. The ASB19 caliber features a patented equal force spring system that ensures a constant energy release to the movement. Thanks to a micro-rotor, the watch remains exceptionally slim without sacrificing power. The fully open-worked design reveals the mechanical precision behind each tick. Three sculptural 'finger bridges' create a powerful geometric landscape within the case. The floating, eccentrically placed time indication enhances the depth effect of the design. High-quality finishes such as hand-engraved guilloché, Geneva stripes, and perlage make every detail a visual feast. This watch is a paragon of Swiss craftsmanship where technique and aesthetics seamlessly come together.
