Unworn, Zenith Pilot Automatic, Ref#03.4000.3620/21.I001, box and papers

The Zenith Pilot Automatic 03.4000.3620/21.I001 is a contemporary reinterpretation of aviation-inspired watchmaking that combines robust design with refined performance. Housed in a 40 mm stainless steel case with a signature oversized crown, this model presents a striking black corrugated dial with large Arabic numerals and generous luminescent hands for outstanding legibility — hallmarks of Zenith’s pilot heritage. At its heart lies the El Primero 3620 high-frequency automatic movement, delivering reliable precision with central hours, minutes and seconds, a date display at 6 o’clock, and an approximate 60-hour power reserve that ensures dependable performance both day and night. The watch is equipped with two interchangeable straps — a black cordura-effect rubber strap for a sporty everyday look and a brown calfskin leather strap for a more classic style — enhancing its versatility and wearability in any setting. With 100 m water resistance, sapphire crystal and a transparent caseback revealing the finely finished movement, this Zenith Pilot Automatic is a blend of technical prowess and timeless character. The watch is unworn in like-new condition, comes with box and papers, and includes warranty documents dated — an exceptional find for collectors and enthusiasts alike.
