High-tech meets sophisticated style in the Khaki Aviation Converter. The bidirectional rotating bezel with slide rule easily performs complicated calculations and conversions, and the most advanced anti-magnetic silicon hairspring, NivachronTM, ensures accuracy in any environment. Perfect for the modern pilot or urban jet setter, the 42mm black dial surrounds the H-10 automatic movement with 80 hours of power reserve. A three-hand movement with date, the H-10 features elaborate colimaçon and pearl contrasting motifs for the American Classic models and clean surfaces for the pilot's watches.
