All in-house manufactured Defakto watch cases are made of highly durable 316L stainless steel, which is characterized by its particularly high resistance to corrosion. The black coating of some watches consists of PVD, a high-strength material for the initial hardening of industrial milling drills. The built-in, high-quality movements are Swiss Made (ETA 2824-2, Ronda 712, Ronda 6004.D) and are known for their precision and reliability in everyday life.
