Grand Seiko Heritage Champagne Automatic Spring Drive 3-Day SBGA373
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 combination of a tempered steel hand and a dial with a thick, silver radiant finish that makes use of Grand SeikoÕs special technology delivers simple and sophisticated quality that wearers can enjoy at any age, coupled with the elegantly radiant case achieved through Zaratsu polishing.
The movement of the blue steel 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.
