This watch, inspired by the Genbi Gorge, combines natural elegance with exceptional watchmaking performance.

A Watch Inspired by the Breathtaking Nature of the Genbi Gorge
In the south of Iwate Prefecture, home to the Grand Seiko Studio Shizukuishi, the Iwai River winds its way through the spectacular Genbi Gorge, also known as “Genbikei” in Japanese. The unique hues of its waters, rocks and vegetation inspired our craftsmen to create the dial of this limited-edition watch.
A dial capturing the beauty of the Genbi Gorge
The Iwai River, rising from Mount Kurikoma and a tributary of the Kitakami River, flows into the Pacific Ocean. As it flows through the two-kilometre-long Genbi Gorge, it creates an enchanting landscape, where the green and blue hues of the clear stream mingle with the wild valley. Recognized as a Natural Monument in Japan, this mystical landscape inspired our master watchmakers to design a textured dial in light green tones, reflecting the natural harmony and gentle murmur of the Iwai River.
The Premier Garde-Temps in Ever-Brilliant Steel from the Evolution 9 Collection
This watch is the first in the Evolution 9 Collection to be made in Ever-Brilliant Steel. This unique alloy offers superior brilliance to traditional stainless steel and enhanced corrosion resistance. Our engineers have developed a new method of treating this steel, ensuring that even brushed surfaces present a brilliant white hue, sublimating the aesthetics characteristic of Grand Seiko style.
Calibre 9SA5
Equipped with a high-performance double-pulse escapement and two barrels, Calibre 9SA5 offers an 80-hour power reserve when wound. Its unique horizontal construction reduces the weight of the movement, adding to the lightness and comfort of the timepiece.
