Channeling the gentle rhythm of the waters of Lake Suwa

Lake Suwa sits to the southeast of the Shinshu Watch Studio, where Grand Seiko crafts all Spring Drive watches. The new Grand Seiko Evolution 9 Style SLGA021 is inspired by this serene body of water, featuring a dark blue dial that recalls gently lapping waves along the water's surface just before dawn.

Representative of the Evolution 9 Style, the 40mm stainless steel case has a lower profile and center of gravity, ensuring a comfortable fit on the wrist. Its faceted mid-case features a blend of Grand Seiko's Zaratsu polishing and hairline finishing, giving the whole watch a dynamic look and feel. This level of finishing is accomplished by hand as it demands a high degree of skill.

Powered by Spring Drive Caliber 9RA2, SLGA021 has a notable 120-hour (5-day) power reserve and an improved accuracy of ±0.5 seconds per day, or ±10 seconds per month. 9RA2 takes the power-reserve indicator off the dial and moves it to the case back side of the watch. The seconds hand glides across the SLGA021’s textured blue dial, evoking the nature of time.
