The 45GS arrived in 1968 as a hand-wound high-beat Grand Seiko running at 36,000 vibrations per hour. Caliber 4520 shows the time only, while caliber 4522 adds a date.
The 45GS shares the flat surfaces and sharp facets of the Grand Seiko Style. Collectors look for crisp case lines, an original dial and hands, and a movement serviced by someone who knows high-beat Seiko calibers.
