Grand Seiko Heritage SBGA465 Spring Drive Watch Morning Frost Dial
Grand Seiko SBGA465 Heritage Collection Spring Drive Watch
The Grand Seiko SBGA465 is a Heritage Collection watch powered by the Spring Drive Caliber 9R65. It combines a stainless steel case with a textured white and silver-toned “Morning Frost” dial inspired by frost in Japan’s Shinshu region.
The 40 mm case features a contemporary interpretation of Grand Seiko’s 1967 44GS design, dual-curved sapphire crystal, inner anti-reflective coating, and a solid screw caseback with the Grand Seiko Lion emblem. The Spring Drive movement offers automatic and manual winding, approximately 72 hours of power reserve, and the characteristic smooth glide of the seconds hand.
The watch includes a date display, power-reserve indicator, screw-down crown, and stainless steel bracelet with a three-fold push-button clasp. Water resistance is rated at 10 bar, making it suitable for everyday wear.
