Heritage Collection SBGA375

Grand Seiko’s distinctive design language, known as the Grand Seiko Style, was established with the introduction of the 44GS in 1967. The SBGA375 features a case that modernizes that iconic design, paired with a dial in lustrous midnight blue that radiates a powerful brilliance. The watch is powered by the Spring Drive Caliber 9R65, an automatic movement with a power reserve indicator and a maximum power reserve of approximately 72 hours (about three days) when fully wound.
