IWC Pilot's Watch Steel — Midnight Blue Chronograph Dial | Ref. IW377717

Among the most evocative expressions of IWC's aviation heritage, the Pilot's Watch Chronograph Edition «Le Petit Prince» renders the iconic midnight blue dial as a tribute to Antoine de Saint-Exupéry's beloved aviator-philosopher. The 43 mm stainless steel case, measuring a substantial 15 mm in thickness, incorporates a soft-iron inner cage that forms a Faraday shield — IWC's time-honoured defence against magnetic field interference that has defined its pilot's watch lineage since the 1940s. The engraved caseback and screw-in crown underscore the functional rigour expected of professional cockpit instrumentation.

At the heart of the IW377717 beats Calibre 79320, a self-winding movement delivering approximately 44 hours of power reserve. The integrated chronograph mechanism records elapsed time to hours, minutes, and seconds via the stopwatch subdials, while a combined date and day display keeps the wearer fully informed of the calendar. A small hacking seconds mechanism allows for precise time synchronisation — a detail borrowed from military-specification timekeeping. The convex sapphire crystal, anti-reflectively coated on both sides, ensures legibility across a wide range of lighting angles.

The midnight blue dial — a colour synonymous with the nocturnal sky familiar to any aviator — carries luminescent coatings on hands and indices to guarantee instrument-grade readability. The stainless steel bracelet offers robust wearability consistent with the watch's operational character, while the overall aesthetic balance between utility and artistry is quintessentially Schaffhausen. Water resistance to 6 bar completes a specification sheet that speaks as fluently to the collector as to the flight enthusiast.
