Its sharp case lines and subdued gray dial exude a sense of luxury. The highly legible bar indexes and sophisticated design blend naturally into business settings and fashion-forward styles. This vintage Grand Seiko is for the mature adult, combining precision, practicality, and elegance. \u003cbr\u003e\u003cbr\u003eThe 56 series Hi-Beat movement installed in 1970s Grand Seiko watches is an automatic winding mechanism that achieves stable accuracy through high vibrations of 28,800 beats per hour.
