9F Quartz model with time difference adjustment function Equipped with the new quartz caliber "9F85" which has a time difference adjustment function that only moves the hour hand. By moving the hour hand independently without stopping the watch, the time difference can be adjusted without losing the high accuracy of the quartz watch. Visibility is improved by the sharp, long hands and the three-dimensional indexes with finely chamfered edges. The calm navy blue dial matches the standard case design and 40 mm size, making it suitable for any situation. It is a member of Grand Seiko's new heritage collection that is thin but has a dignified presence.
