An elegant black dial
The dial is black with a delicate sunburst finish. It resonates with the pink gold color hands and indexes to display an expression of calm gorgeousness.
A smooth case design that blends with the motion of the second hand
Inspired by the flowing motion of the second hand, a characteristic of the spring drive, the case is designed to uniformly flow from the bezel to the case side and the case back.
＊In an actual product, the case back direction might be different from the photograph.
A see-through case back so you can fully enjoy the beautiful mechanical movement
The words “Grand Seiko Boutique Limited Edition” are displayed proudly on the sapphire glass case back, which also is marked with the Grand Seiko lion emblem.

AUTOMATIC SPRING DRIVE 3-DAY Caliber 9R65
Our company 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.
Caliber 9R65 is currently the most standard of the 9R Spring Drive movements, and is used in many Grand Seiko models.
