Grand Seiko SBGA471

Features

Inspired by Autumn’s First Frost.
USA Special Edition

Celebrating the end of Autumn when the first frost embraces the forest, SBGA471 Sōkō Frost is one of two new, US-exclusive Special Edition timepieces exploring the Japanese sekki. The light blue dial with its vertical texture and tonal accents is inspired by the frozen trunks of the bamboo trees that line the famed Arashiyama forest. The acclaimed stainless steel 44GS case measures 40mm in diameter and features perfectly flat and mirror polished surfaces, a detail made possible via Grand Seiko’s renowned Zaratsu finishing method.
