The first morning dew appears and the wind feels cool against the skin. It is still the end of August but summer is short in Shizukuishi and the early signs of autumn are in the air. The green of the leaves on the trees is increasingly deep and, with its delicately textured surface, the dial reflects its own special beauty.
