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. Each GMT watch in this new collection celebrates one of the year’s 24 seasonal phases or "sekki."

Representing "Summer" is SBGJ249. High summer approaches and, at last, the rainy season ends. In Shōsho, 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.
