Description
The Grand Seiko 9581-7000, launched in 1988, powered early Grand Seiko quartz models with thermistor-based temperature compensation. It offered high accuracy and quiet refinement before the 9F series took over in the mid-1990s. Collectors value it for its precision and transitional role in Seiko’s HAQ evolution.
