Running on Grand Seiko’s unique Spring Drive caliber, SBGA375 features Grand Seiko’s modern 44GS design, a contemporary take on the 44GS that first launched in 1967 and formed the cornerstone of the Grand Seiko Style. The deep blue dial has multi-faceted hands and hour indexes, and it features an indicator by 8 o’clock, which tracks the 72-hour power reserve of the movement. Emblematic of Spring Drive, the second hand glides across the dial in a smooth continuous motion, reflecting the continuous flow of time itself. The decorated caliber can be viewed through the exhibition case back.
