The characteristic features of the Black Bay Dark model center on the 41 mm wide steel case, finished with a black PVD-treated coating. Directly derived from the thin film technology originally developed by NASA for its various space programs, PVD or “Physical Vapor Deposition” enables practically any inorganic material to be bonded with metals. The Black Bay Dark has an entirely satin finished matte finish, giving it the appearance of black military utility equipment.
