The Chromeworks Sable is a full-arm replacement engineered to sub-millimeter motor tolerances, using a layered piezoelectric actuator system in each finger joint that allows positional accuracy to 0.04mm without tremor. The arm's neural integration suite runs a proprietary vibration-cancellation algorithm that filters environmental micro-tremors from the operator's own body, ensuring motionless precision even when the user is fatigued, stressed, or under mild stimulant load. The exterior is matte-finish surgical chrome with slim profile articulation, designed to fit inside standard sterile-field gloves.

The Sable is the gold standard for microsurgeons, bomb disposal technicians, and high-end watchmakers in GLMZ's Tier 4 professional class. CHROMEWORKS markets it aggressively through hospital licensing programs and licensed medical tech distributors, making it the most common precision arm in Spire-adjacent clinic settings. It carries significant social cachet — a Sable arm at a dinner table announces a career built on skill, not brute labor.
