As the water of Lake Suwa freezes in the winter, the 'Omiwatari' tradition means this is where the Gods walk over over the ice. The watchmakers at the Shinshu Watch Studio were thus inspired to create a special dial with subtle textures in blue for a hand-winding Spring Drive timepiece. The watch measures 38.5mm by 10.2 mm and houses the 9R31 manual wind movement with 72 hours of power reserve.

SBGY007 is not a limited edition but because of its popularity, most retailers reported that the model has been quickly 'sold out'.

In the middle of the Iwai River lies the Genbi Valley, one of Iwate Prefecture's most stunning and picturesque greenery scenes in Hiraizumi. In November 2021, Grand Seiko launched three models exclusively for the US market (using a Japanese painting method called Kirazuri), each with 140 pieces: SBGW273 (featuring a light green hue), SBGW275 (rendered in teal to denote the flowing waters) and SBGW277. The last named model is characterized by a medium green tone - a literal interpretation of the vegetation that lines the valley walls.

The model is slightly smaller - it measures 37.3mm in diameter and 11.6 mm in thickness. It is driven by calibre 9S64, a mechanical manual wind, again with 72 hours of power reserve.

Which one do you prefer?

Key Points from the Discussion

The 'Omiwatari' SBGY007 with its ice-blue, textured dial is preferred for its unique color and texture, which beautifully reflects the rare Japanese ice-formation phenomenon.
The SBGY007's Spring Drive movement, 72-hour power reserve, and absence of visible screw heads on the case back are compelling features, with the dial texture being a decisive factor despite the case shape being reminiscent of the 1960s.
The author ultimately acquired both watches, citing their relative affordability in steel cases, highlighting the appeal of owning both distinct expressions of Grand Seiko craftsmanship.
The Spring Drive movement in the SBGY007 is noted for its exceptional accuracy of +/- 1 second per day, while the 'Kirazuri' method on the Genbi Valley dial translates to 'sparkling painting' inspired by dense flora.
The SBGY007's textured dial and near-perfect proportions of 38.5mm x 10mm are highly favored, suggesting it's difficult to make a wrong choice between the two models.
The 'Omiwatari' phenomenon in Lake Suwa, where ice freezes in a unique line, is considered a rare and inspiring natural event.

The Spring Drive movement is incredibly accurate+/- 1 second per day. The Kirazuri method used on the dial of the Genbi Valley translates into "sparkling painting" with the help of dense flora.
