The Revival 03.A3818-U.400/33.M384, seen from the bench

The Zenith El Primero A3818 Revival represents a conscious resurrection of the legendary 1969 A384 chronograph, debuted in the year of the El Primero caliber. The model features a distinctive tonneau case of 37.00 mm diameter in stainless steel, paired with a 20 mm lug width. Powered by the El Primero 400 caliber with column wheel, it delivers superior chronographic precision and a high oscillation frequency. The dial combines hour, minute, small second, date window and three counters in a balanced complication, with the tonneau case geometry reducing reflections for optimal readability.
