Running on Grand Seiko’s unique Spring Drive caliber, SBGA373 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 radiant silver 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, here in tempered blue, glides across the dial, reflecting the continuous flow of time itself. The decorated caliber can be viewed through the exhibition case back
