Grand Seiko Heritage Blue Spring Drive 3-Day SBGA375
Powered by Grand SeikoÕs unique Spring Drive calibre, this model features 44GS Contemporary Design, a contemporary take on the design of the 44GS, which was launched in 1967 and formed the cornerstone of the Grand Seiko design philosophy, Grand Seiko Style.
The dial of midnight blue as close to black as possible, coupled with the elegantly radiant case achieved through Zaratsu polishing, delivers both refined taste and high visibility at the same time.
The movement of the second hand over the dial further highlights Grand SeikoÕs original glide motion, reflecting the natural and continuous flow of time itself. It has a 72-hour (3-day) power reserve, and a power reserve indicator on the bottom left of the dial.
Calibre 9R65:
Grand Seiko unveiled Spring Drive in 1999, but its lack of a sufficiently effective automatic winding mechanism and 72-hour power reserve prevent its adoption in the Grand Seiko line. After a further four years of development, the first Grand Seiko 9R Spring Drive was created.
The winding system and drive time were improved from the existing 48-hour manual winding system to an automatic 72-hour power reserve. The automatic winding mechanism uses Seiko's original Magic Lever mechanism developed in 1959, but with improved productivity, maintainability, and durability to enhance winding efficiency.
Calibre 9R65 is currently the most standard of the 9R Spring Drive movements, and is used in many Grand Seiko models.
