Powered by the slim, hand-wound movement, Caliber 9S64, this watch is the epitome of simple refinement. The dial is simple and clean but, when viewed through the sapphire case back, the intricate perfection of the engineering of the hand-assembled and adjusted movement is abundantly and
satisfyingly clear. Thanks to a long mainspring and a balance both made of a proprietary metals, this watch has a high and stable accuracy rate and a power reserve of 72 hours.
The dial is deep green in color and is inspired by Byōka, which marks the transition from summer to autumn. 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.
