Grand Seiko Heritage Collection

Grand Seiko's quartz is built to a standard the industry does not require — tuned and adjusted to the maison's own accuracy specification, tighter than the ordinary baseline. Every surface of the steel case is Zaratsu-polished by hand against a rotating tin plate, producing mirrors with no distortion, on a dial finished to the same standard as the mechanical collection.
