This simply finished model with no crown guard is driven by a Grand Seiko’s unique Spring Drive calibre, which combines the motive force of a mainspring with the high precision of a quartz watch.
With a case size under 40mm, the watch adorns the wrist with an elegant subtlety.
The dial makes use of Grand Seiko technology to effect a deep silver finish, giving off a radial sheen that projects a lustrous sense of depth.
The slender shape of the raised indices complements the sharpness of the power reserve indicator, while the clear expanse of the dial combines with the smooth movements of Grand Seiko’s original second hand.
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.
