The Grand Seiko Spring Drive 40mm Heritage Collection Midnight Blue (Ref. SBGA439) is a masterfully crafted timepiece, serving as a definitive example of the understated luxury and technical perfection for which Grand Seiko is renowned.
This model is distinguished by its 40mm stainless steel case with the characteristic Zaratsu polishing and a smooth bezel, framing a deep midnight blue dial with power reserve indicator, presented on a stainless steel bracelet. It is unworn.
Technically, this watch is powered by the Spring Drive Caliber 9R65, a revolutionary movement with a 72-hour power reserve that combines the precision of quartz with the soul of a mechanical watch, ensuring an unparalleled smooth and accurate feel.
