Founded in 1967 by the legendary Armin Strom, a master in the art of hand-skeletonization, the Armin Strom brand has long been synonymous with intricate craftsmanship and innovation. Fifteen years ago, Armin Strom metamorphosed from a solo endeavor into a fully integrated manufacture brand under the visionary leadership of entrepreneur Serge Michel and master horologist Claude Greisler.

Since 2009, these lifelong friends have immersed themselves in the horological arts, cultivating an independent manufacture staffed by a dedicated team of 38, including 22 masterful watchmakers capable of transforming raw steel bars into an array of intricate, interlinked watch components. Their dedication has culminated in the creation of 17 unique calibers, each showcasing the brand’s iconic open-worked design, distributed across Armin Strom’s three principal collections: System 78, Resonance, and Masterpiece. After Claude and Serge established the Armin Strom manufacture in Biel/Bienne, the brand quickly made its mark in the horological world. Within just one year, Armin Strom unveiled its inaugural in-house timepiece and movement, the “One Week,” distinguished by its impressive seven-day power reserve.

Continuing its trajectory of innovation, Armin Strom launched its first in-house tourbillon in 2012. The brand’s commitment to design excellence was recognized in 2015 when it received the first of three Red Dot Awards for the Skeleton Pure Water.
