Grand Seiko “Genbi Valley” Limited Edition – 40 mm

Reference Number
SLGH021G

The Genbi Valley in Japan has been designated a Place of Scenic Beauty and Natural Monument. It exists mid-stream on the Iwai River in Iwate Prefecture, where Grand Seiko’s mechanical watches are manufactured. The grand and mysterious scenery of the Genbi Valley is expressed in this watch’s dial via a new molded pattern and light-green coloration. The case and bracelet incorporate Ever-Brilliant Steel, a material that boasts the highest level of corrosion resistance for stainless steel in the world, and this model is the first in the Evolution 9 Collection to feature it. The material’s tendency to exhibit a white shine pairs well with the vivid green color of the dial. The Caliber 9SA5 is a ten-beat movement that is capable of 80 hours of continuous operation when the watch is fully wound.
