Grand Seiko Heritage Collection 9R Spring Drive Soko USA Limited Edition SBGA429
Inspired by the end of Autumn "Soko" Special Edition.
The new Grand Seiko SBGA429 timepieces celebrate sōkō, the end of Autumn when the first frost embraces the forest. The green accent colors featured on the second's 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 “shadow” grey 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 Grand Seiko 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 like 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 second's hand around the dial.
