The changing Dial
This picture gives you an idea of the changing character of the dial. The dial is radially polished and the little grooves reflect light differently when changing the viewing angle. The dial does not really change the color, but certain areas appear darker or brighter. In direct sunlight, the dial is really shimmering, particularly nice to look at.
