Bi - metal Black Submariner

The “Black Submariner” gets its name from the black dial and the black unidirectional rotating ceramic bezel. The black dial is simple and clear, and the luminescent hour markers and hands facilitate time - reading in low - light conditions; the black ceramic bezel has a unidirectional rotation function for diving timekeeping. The ceramic material is wear - resistant, corrosion - resistant, and the scales remain clear for a long time.
