Specifications

About this reference

This mechanical chronograph was created in the Evolution 9 Style, a unique design method that combines the spirit of Grand Seiko and the aesthetic beauty of Japan to reach new heights. The dial captures Mount Iwate, topped with fresh snow, a merger of the harsh winter’s crisp blue sky and the subtle blue tint of the newly fallen snow. The deep snowfall is represented by the snow-blue dial color and an embossed pattern inspired by the mountain’s ridgelines.
