Features
A Simple and Compact Spring Drive, at is most elegant
This simply finished model with no crown guard is driven by a Grand Seiko’s unique Spring Drive caliber, 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.
