Production of the amorphous metal housing takes place in Germany and includes both automated and manual steps. A computer-controlled laser sinters a thin coat of metal powder, welding the molten alloy to the already hardened material beneath it. Layer by layer, the part builds up to its ultimate shape. A technician then removes any artifacts of the manufacturing process by hand. After thorough cleaning, steel shot blasting, polishing, and sophisticated surface treatment, the housing assumes its final, extremely durable aesthetic. Even daily use leaves practically no evidence in the form of scratches or wear.
