A single glance is enough to understand the fascination around the Zenith A386: the tri-color register, the 38 mm case and the weirdly attractive Gay Frères ladder-bracelet make a killer mix. And it is not only about looks – the reference A386 was one of the first Zeniths to carry the groundbreaking El Primero caliber. In 1969, this was one of the first automatic chronograph movements ever offered, alongside the Seiko 6139 and the Chronomatic movement (the latter born out of a technical collaboration between Heuer, Breitling, and Hamilton). The debate still rages on about who was really first, but in any case, the El Primero was the only one to boast a 36,000 vph high-beat frequency. The watch here also stands out thanks to its outstanding condition, with an unpolished case, nicely patinated lume, and all original parts.
