Grand Seiko Heritage Spring Drive SBGA415

The Grand Seiko SBGA415 is a Spring Drive timepiece from the Heritage Collection, featuring a light gray dial with a delicate texture inspired by the Taisetsu season—the deep snow of winter. This design captures the quiet beauty of snow-covered pine trees, reflecting Grand Seiko’s dedication to showcasing the natural beauty of Japan. The case is made of high-intensity titanium, which is approximately 30% lighter than stainless steel, measuring 40.0 mm in diameter, 12.8 mm in thickness, and 47.0 mm from lug to lug, offering both durability and comfort.

The SBGA415 is powered by the Spring Drive Caliber 9R65, delivering a 72-hour power reserve and precise timekeeping with an accuracy of ±15 seconds per month. The seconds hand moves in a smooth, gliding motion, characteristic 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 an anti-reflective coating on the inner surface for clear visibility. The see-through screw case back allows a view of the movement, while water resistance is rated at 10 bar, and magnetic resistance is 4,800 A/m. The watch is completed with a high-intensity titanium bracelet, secured by a three-fold clasp with push-button release, and weighs approximately 102 grams.
