Grand Seiko - 1971 Hi-Beat 5645-7000

WHAT WE LOVE:

Produced during the golden era of Grand Seiko mechanical watchmaking, the 5645-7000 stands out with its clean white dial, subtle finishing, and ab elegant cushion-shaped case. As part of the 56GS series, it represents Grand Seiko’s dedication to precise, high-frequency timekeeping before the quartz revolution. The case design feels distinct yet timeless — a quiet example of Seiko’s form-follows-function design ethos from the early 1970s. The stainless steel case is paired with a flat hardlex crystal and a screw-down caseback.
