What to know
The gold Big Pilot ProSet uses a dark olive-green dial rather than the blue of the Le Petit Prince versions. Gold appliqués and gold-plated luminous hands repeat the colour of its 18-carat 5N-gold case. The calendar retains a four-digit year, small seconds and a Double Moon display within the established Big Pilot layout.
Reference IW329602 houses automatic calibre 82665. Its gear-based perpetual-calendar mechanism allows corrections both forwards and backwards from a single crown position, while Pellaton winding supplies a 60-hour reserve. The 42 mm case measures 14 mm thick and is rated to 10 bar. An olive-green buffalo-leather strap and gold pin buckle complete the configuration.
