Grand Seiko Heritage Spring Drive SBGA413

The Grand Seiko SBGA413 is a Spring Drive timepiece from the Heritage Collection, featuring a dial design inspired by Japan’s natural beauty. The dial’s light pink hue reflects the fleeting and delicate atmosphere of spring, capturing the spirit of the changing seasons. The stainless steel case measures 40.0 mm in diameter, 12.8 mm in thickness, and 47.0 mm from lug to lug, offering a comfortable and balanced fit.

Powered by the Spring Drive Caliber 9R65, the SBGA413 provides an approximate 72-hour power reserve and an accuracy of ±15 seconds per month. The smooth movement of the seconds hand is a signature of Spring Drive technology. Additional features include a date display at 3 o’clock, a power reserve indicator between 7 and 8 o’clock, and a dual-curved sapphire crystal with anti-reflective coating on the inner surface for clear visibility. The see-through screw case back offers a view of the movement, while the watch also provides water resistance to 10 bar, magnetic resistance of 4,800 A/m, and weighs approximately 100 grams. A stainless steel bracelet with a three-fold clasp and push-button release completes the design, combining refined aesthetics with everyday functionality.
