Grand Seiko Evolution 9 Collection Spring Drive Evolution 9 UFA Atera Valley Blue-Green Stainless Steel Watch Full Set SLGB011G

The Grand Seiko Evolution 9 Spring Drive U.F.A. SLGB011G is a stainless steel men's wristwatch with a round 40 mm case and a blue dial. It is powered by the Spring Drive U.F.A. Caliber 9RB2, a movement rated to an annual accuracy of ±20 seconds. The Atera Valley reference in the model name links the dial colour to a specific landscape, giving the watch a defined visual identity. It is offered as a full set with the original inner and outer boxes, hang tags, warranty card dated 09/2026, operating instructions, and limited warranty booklet.

The 72-hour power reserve shapes how the watch is used between wearings: fully wound, it continues running for approximately three days, so it can be set aside and picked up again without resetting. The case and bracelet are made from Ever-Brilliant Steel, a stainless-steel alloy noted for corrosion resistance and a bright hue, which affects both the appearance of the metal and its behaviour under everyday exposure. The sapphire crystal covers the dial, and 10 ATM water resistance covers contact with water such as rain or hand washing. The fully linked bracelet fits wrists up to 8.25 inches.
