TimeHunter Analysis

Collector context

Updated Daytona calibre with revised escapement and finishing. 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.
