Details: 
Shōsho. High summer approaches and, at last, the rainy season ends. The warm wind creates delicate ripples in the many thousands of lakes and ponds that shimmer in the early summer sun throughout Japan. The wave pattern dial brings Shōsho to life as the long, tapered seconds hand, driven by the high beat caliber, moves powerfully across the dial.
