This limited edition model with a beautiful dial that looks like a field of snow reflecting the morning glow of the Hotaka mountain range, inherits the design of Grand Seiko's first Spring Drive model SBGA001/003 created in 2004, and celebrates the 20th anniversary of the birth of Caliber 9R. The mountains of the Hotaka mountain range, overlooked from the "Shinshu Toki no Takumi Kobo" where the Spring Drive movement is manufactured, are covered with snow for several months every year, and the wind-blown snow surface creates delicate wind patterns in the cool, dry air. This model features a gradation dial that resembles the beautifully tinted snowfields in the morning glow, as seen on the Hotaka mountain range. The case and bracelet are made of bright titanium, which is more scratch-resistant and whiter than regular titanium, creating a comfortable fit. The movement is equipped with Caliber 9R65, which runs for approximately 72 hours at maximum winding, and the remaining duration can be checked on the power reserve display on the lower left of the dial.
