The appearance of the DC 57 black with its extremely hard DAMEST® coating is a little more restrained than the black dial of the DC 56 version through its bright dial. The black case gives the timepiece an authentic high-tech look. The chronograph of this particular watch family is characterized by reliable timekeeping, perfect readability and extremely robust technology. This combination of the classic chronograph is an extraordinary eye-catcher. The black coating permanently preserves its noble, semi-matte appearance.
