This model’s case embodies the Evolution 9 Style, a further development of the Grand Seiko Style design language established in 1967. With its textured pattern, the blue dial expresses the surface of Lake Suwa before dawn. This body of water is located in an area near the place where Spring Drive watches are crafted at the Shinshu Watch Studio, which is housed in a Seiko Epson facility in the city of Shiojiri. This model is powered by the Spring Drive 5 Days Caliber 9RA2, which features an innovative high-precision mechanism that compensates for variations in the oscillator’s performance by measuring the temperature 540 times per hour and offers a power reserve of approximately 120 hours (about five days) when fully wound.
