Collector context
Five-day Spring Drive calibre with improved thermal compensation. 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.
