Zenith A783 El Primero Stainless Steel C. 1971

The Zenith El Primero A783, introduced circa 1971, represents one of the early executions of one of horology's most important automatic chronographs. This reference, limited to around 1,500 pieces and produced for just one year, features the legendary 3019 PHC high-frequency caliber, celebrated for its role not only in Zenith's own lineup but also as the foundation for the famed Rolex Daytona Caliber 4030. The A783’s 38mm stainless steel case, paired with its original and distinct steel bracelet, houses a striking silver dial accented by distinctive blue subdials—an instantly recognizable hallmark for collectors. The dial’s tachymeter scale and colored registers create legibility and stylistic balance rare for early 1970s sports chronographs. The 3019 PHC movement beats at an impressive 36,000 vph, a technical marvel in its era, ensuring optimal chronometric precision. As a vintage El Primero, the A783 occupies a special place at the crossroads of design innovation and mechanical prowess, making it a highly coveted addition to any serious chronograph collection.
