The Grand Seiko GMT watch celebrates ever-changing seasons.
In Japan, each of the four seasons of the year is experienced in six phases and all have their own distinct characters. The subtle changes from one to the next bring the nature of time ever closer to our senses. The GMT watch celebrates one of the year’s 24 seasonal phases or sekki.
Shosho. 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 Shosho to life as the long, tapered seconds hand, driven by the high beat caliber, moves powerfully across the dial.
