Description
The Zenith 03.4000.3652/21.I001 Pilot Big Date Flyback is an impressive addition to the brand’s legendary range of aviation watches. Housed in a robust 42.5mm stainless steel case, this reference reinterprets the pilot chronograph ideal with modern engineering while retaining signature design codes such as the oversized crown and bold, highly legible black corrugated dial. The El Primero 3652 high-frequency caliber powers this model, providing the rare combination of a precise flyback chronograph and a highly legible big date—two complications that underscore the watch’s utility for aviators and enthusiasts alike. The inclusion of luminescent Arabic numerals and colored indicators ensures instant readability in any environment. As with every El Primero-powered Zenith, expect exceptional accuracy at 5Hz (36,000 vibrations per hour) and a substantial 60-hour power reserve, both feats of technical achievement still rarely matched. The reference’s quick-change rubber strap system complements an active lifestyle, a nod to contemporary practicality. As the aviation genre continues to evolve, this Pilot remains rooted in Zenith’s pioneering heritage, making it a compelling proposition for collectors who admire the brand’s relentless pursuit of precision and legibility. This model stands as a testament to the enduring relevance of the pilot’s chronograph in the twenty-first century. Like New with Zenith box, additional Zenith strap and papers dated 2023.
