Grand Seiko Heritage

Limited edition only available at the Grand Seiko Boutique

The blue dial—which features a 'Mount Iwate pattern' showing the ridgelines of the magnificent mountain visible from the Shizukuishi Watch Studio where all Grand Seiko mechanical timepieces are made— expresses the beauty of winter mountain scenery emerging faintly through moonlight reflected on snow.

The exterior design is a modern take on the stunning 'Grand Seiko Style'—the embodiment of the Grand Seiko design philosophy which was first established for the 44GS in 1967—and features a distortion-free, wide mirror surface throughout.

The words “Grand Seiko Boutique Limited Edition” are displayed proudly on the sapphire glass case back, which also is marked with the Grand Seiko lion emblem.
