The natural beauty of tree rings

A unique and natural dial fits perfectly in a distinctive overall design.

In 1881, Kintaro Hattori founded the company that would later be known as Seiko and led it until his death at the age of 73 in 1934. His philosophy was that his company should be “Always one step ahead of the rest” and, as they went about their duties, he promoted to his colleagues his life lesson “Don’t run but always keep going.” His words have always had a powerful resonance and inspire the company still.

While it was not created until 1960, nothing better expresses their power than Grand Seiko with its unique design, leading edge manufacturing and exquisite finishing. In honor of the 140th anniversary of the foundation of the company, Grand Seiko announces a remarkable creation that embodies Kintaro Hattori’s spirit and vision. The watch incorporates a dial design that captures the natural beauty of tree rings.

A unique dial and a new Spring Drive movement capture the Nature of Time.

The dial delights the eye with its organic feel and brings to life Grand Seiko’s conception of the Nature of Time. The minuscule but visible variations in the dial’s depth reveal the subtlety of the dark and light tones of the wood grain. The brown tone of the dial perfectly matches the 18k rose gold case to give the watch a gentle and warm feel, and the Zaratsu polished distortion-free mirror finish and the delicate hairline finish alternate on the case to create a quiet and harmonious glow. As is Grand Seiko’s tradition, the SD (Special Dial) mark at the 6 o’clock position denotes the use of gold for the indexes. The hour hand is large in volume and crafted to align exactly with the grooved and prominent hour markers, enhancing the legibility of the time.
The watch is powered by the new Grand Seiko Spring Drive 5 Days Calibre 9RA2, which inherits all the performance characteristics of the Spring Drive Calibre 9RA5 introduced in 2020 in celebration of the 60th anniversary of Grand Seiko, but the power reserve indicator is now visible through the sapphire crystal case back and the beauty of the movement’s finishing is revealed for the first time.

The design is true to the Grand Seiko Style defined back in 1967 with the celebrated 44GS, but its heritage is combined with a powerful contemporary feel that points towards a new era.

SLGA008 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.
