The Evolution 9 Style

In 2020, Grand Seiko introduced a new design philosophy called the Evolution 9 Style. It was based, of course, on the Grand Seiko Style, which has always defined the design of all Grand Seiko watches and continues to do so. The Evolution 9 Style preserves the fundamentals of the Grand Seiko Style but adapts them for a new generation by setting new standards of legibility, ease of use and beauty.

White birch dial

The calmness of the white birch forest in response to the quiet and smooth movement of the seconds hand created by the Spring Drive movement is expressed by the carefully made dial of the mold.

Spring Drive 5 Days, Caliber 9RA2

SLGA009 is powered by the Grand Seiko Spring Drive 5 Days Caliber 9RA2. The movement is equipped with an "Offset Magic Lever" to reduce its thickness and incorporates two barrels to provide up to 120 hours of power reserve. The beauty of the movement reveals the uniquely Japanese aesthetic for which Grand Seiko is renowned. The delicate texture of the movement's finish reflects the frost that winter brings to the forests in Shinshu where all Spring Drive watches are made. The bridge line and the edges of the screw holes are diamond cut to reflect the light from any angle and give the movement a quiet glow when seen through the sapphire case back.
