The brand's first 10-beat manual-winding mechanical watch, the 45GS, was launched in 1968 and is now reintroduced in an 18K gold reissue. The sharply angled case is polished to a mirror finish, with curved lines on the sides recreated using modern techniques, embodying the "Grand Seiko Style" based on the principle of "light and shadow" that has been emanating a unique glow since its inception. The dial features the "SEIKO" logo at 12 o'clock, "GS" in the same font as the original, "HI-BEAT", indicating the movement's frequency of 36,000 vibrations per hour, and the "Daini Seikosha" mark, the birthplace of the 45KS, at 6 o'clock.
