Family: ARM
The ARM09 is a manual-winding in-house movement introduced by Armin Strom in 2009 as the brand's first in-house caliber. It features a skeletonized construction with a micro-rotor conversion, enabling both manual winding and automatic energy delivery through the visible rotor. The movement remains in production and underpins several of the brand's display caseback models.
