Grand Seiko Heritage Collection, Soko Special Edition Watch with Silver Dial, 39mm

Item # WGSB2478

The new timepieces celebrate soko, the end of Autumn, when the first frost embraces the forest. The green accent colors featured on the seconds hand and power reserve indicator epitomize the life of the Arashiyama bamboo forest in Kyoto in its peak season at the end of Autumn. The vertical texture of the dials reflects the majestic stalks of the bamboo. Together, the 39.0mm timepieces pay tribute to this moment in nature, when its green hues are dramatically enlivened in the contrasting expression of "light" silver dial.

These remarkable timepieces display the deeply satisfying beauty created by the highest level of Japanese craftsmanship unique to Grand Seiko. The Spring Drive 9R65 Caliber is designed, adjusted and assembled by hand, by acclaimed craftsmen and women at the Shinshu Watch Studio in Japan. Spring Drive, recognized as one of the great innovations in modern watchmaking, is a spring-driven movement with a state-of the-art electro-magnetic regulator that functions without an external power source. Its sole power source is a mainspring, which drives a series of gears as a traditional mechanical watch, and delivers a precision of one second a day, a rate unprecedented for a watch powered by a mainspring. The Spring Drive movement further celebrates the passage of time as a poetic journey with every revolution of the seconds hand around the dial.
