A dial for each seasonal phase, or sekki

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 of these GMT watches celebrates one of the year’s 24 seasonal phases or sekki.

The selected sekki are Shunbun (Spring) , Shōsho (Summer), Kanro (Autumn) and Tōji (Winter). The Shunbun and Shōsho versions feature the Hi-Beat 36000 GMT caliber 9S86 while the Spring Drive GMT caliber 9R66 powers the Kanro and Tōji creations.

Shunbun – SBGJ251

 

It is in Shunbun that the spring equinox finally arrives and everyone senses spring is truly in the air. The cherry trees in the mountains start to bloom and their sakura blossom decorates the slopes. The green dial and rose gold accents perfectly capture the promise of spring.

Shōsho – 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.

Kanro – SBGE271

The evenings draw in and there is a chill in the morning air. The glide motion seconds hand moves silently, like the moon across the night sky. Autumn is at its height.

Tōji – SBGE269

 

The winter solstice is in Tōji. The days are short, the air is crisp and clear and snow muffles the sound of the wind. The dial has the texture and color of a winter landscape as the sun sinks lower in the sky. 

Hi-Beat 36000 or Spring Drive, the hour hands are independently adjustable so that the precision is maintained.

The softly contoured case has the classic yet distinctive Grand Seiko edges that are sharp and angular, and the sides are Zaratsu polished to a distortion-free finish. Both the mechanical and Spring Drive movements are clearly visible through the sapphire case backs and the beauty of their finishing is there to be enjoyed.

Based on a series first presented in the USA, the Shunbun and Shōsho creations will be available in May and the Kanro and Tōji creations in September at the Grand Seiko Boutiques and retail stores worldwide.
