Grand SeikoSS Spring Drive Blue Dial SBGA407

The unique dial pattern is inspired by the wind-swept snow in the mountains of Shinshu. This texture is commonly known as the "Snowflake" and has gained popularity from around the world. To emphasize the delicate dial, it is treated with a subtle blue coloring.

A classic mechanism with a detailed focus, Spring Drive enables high precision equal to that of a quartz watch while using a mainspring used in a mechanical watch as a power source. The maximum winding duration is 72 hours. The movement of the blue steel second hand glides across the snow blue dial.
