To celebrate 160 years of pioneering spirit, Zenith unveils the Pilot Big Date Flyback 160th Anniversary Edition 49.4002.3652/51.I00. Crafted from bright blue micro-blasted ceramic, this exclusive limited edition reimagines Zenith’s aviation heritage with a bold monochrome design.

The 42.5mm case is paired with a titanium crown and rectangular chronograph pushers, while the corrugated blue dial features oversized luminescent Arabic numerals and hands for optimal legibility in all conditions. The integrated big date display, with two large separate discs, ensures instant readability, and thanks to a patented compliant mechanism, the date changes in just 0.007 seconds.

Inside, the latest El Primero 3652 caliber powers the chronograph with both big date and flyback functionality. Designed for rapid operations, the flyback feature allows the chronograph to be reset and restarted with a single push—essential for time-critical aviation calculations. The movement is visible through the sapphire crystal case back, revealing a specially openworked rotor adorned with Zenith’s 160th anniversary emblem.

Limited to 160 pieces worldwide, the Zenith Pilot Big Date Flyback 49.4002.3652/51.I00 is delivered on a matching blue Cordura-effect rubber strap, completing a dynamic tribute to Zenith’s long-standing connection to the world of aviation.
