The IWC Big Pilot reference IW500402, first introduced circa 2005, marks the debut of the Big Pilot in luxurious 18K white gold, instantly elevating its stature among connoisseurs. Powered by the in‑house IWC Caliber 51110 automatic movement—derived from the legendary 5011 and offering an impressive seven‑day (168‑hour) power reserve—this timepiece embodies technical mastery and horological gravitas. Its commanding 46.2 mm white gold case, paired with a striking gray sunburst dial, delivers exceptional legibility and a refined aesthetic that balances bold presence with elegant understatement. The onion‑shaped fluted crown and solid screw‑down case back reinforce its pilot‑watch heritage, while the 60 m water resistance ensures daily practicality. The gray dial, with luminous Arabic numerals, power reserve indicator at 3 o’clock, and date window at 6 o’clock, showcases IWC’s thoughtful functional design. With its manufacture movement, precious metal case, and extended reserve, this Big Pilot is both a technical tour de force and a collector’s grail—rare, historically significant, and emblematic of IWC’s mastery of pilot’s watch tradition. Excellent condition with IWC box and undated papers.
