The natural beauty of tree rings

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.

Features

Time, nature and craftsmanship. SLGH007 embodies the spirit of Kintaro Hattori.

Our founder, Kintaro Hattori’s credo has always had a powerful resonance and inspire Grand Seiko still. The dial captures the nature beauty of annual growth rings of cedar trees in Shizukuishi Shrine near Grand Seiko Studio Shizukuishi. As if stretching back to reveal the very roots of Kintaro's story, a series of delicate and organic lines echo the intricate rings that denote each year's growth. A special anniversary demands that precious metals are used to celebrate it. The case is crafted from Platinum 950.

The overall look of the watch is known as the Evolution 9 Style and it will be an important part of the Grand Seiko’s signature in the years to come. Its powerful hands and grooved, prominent markers ensure perfect legibility, its Zaratsu polished, distortion-free mirror finish and delicate hairline finish alternate give the case a quiet and harmonious glow. The case has a low center of gravity that ensures that the watch sits easily and securely on the wrist.

The high-beat watch is powered by the revolutionary Caliber 9SA5, which offers a power reserve of 80 hours thanks to its enhanced energy efficiency.

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.

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

The dial delights the eye and warms the heart with its organic feel and brings to life Grand Seiko’s conception of the Nature of Time. An almost tactile effect is created by the way the light captures the multi-dimensional texture of the dial. The miniscule but visible variations in the dial’s depth reveal the subtlety of the dark and light tones of the wood grain.

The hour hands are large in volume and are crafted to align exactly with the grooved and prominent hour markers, enhancing the legibility of the time. A distortion-free mirror finish and delicate hairline finish alternate to give the case a quiet and harmonious glow. With its wide lugs and a satisfyingly substantial leather strap, the watch offers perfect comfort and fits solidly and neatly on the wrist.

The high-beat watch is powered by the revolutionary Caliber 9SA5, which offers a power reserve of 80 hours thanks to its enhanced energy efficiency. First presented in 2020, Caliber 9SA5 incorporates three significant developments, the entirely new Dual Impulse Escapement, the Grand Seiko free-sprung balance, and the horizontal gear train which, together, set a new standard in high-beat horology.
