Collector context
Core Grand Seiko mechanical automatic calibre. Evaluate the complete watch rather than the calibre in isolation: condition, regulation, service history and correct parts materially affect ownership quality.
A famous calibre can add historical interest, but maintenance condition remains more important than reputation alone.
