The Grand Seiko Heritage SBGA439 showcases an archetypal design complemented by a dynamic midnight blue dial reminiscent of a moonlit night sky. Diamond-cut hands and multifaceted hour markers stand in sharp contrast against the dial surface.
Powered by the manufacture Caliber 9R65 Spring Drive movement, the seconds hand glides smoothly across the dial without ticking. It delivers an accuracy of ±15 seconds per month along with a 72-hour power reserve displayed near the eight o'clock position.
Crafted with a 40.0mm stainless steel case and matching bracelet, this timepiece is fitted with a dual-curved sapphire crystal and offers 10 bar water resistance.
