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 that gives its wearer a premium feel.
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.
