Zenith El Primero

About this reference

The Zenith El Primero A3818, nicknamed the "Cover Girl," was produced between 1971 and 1972 with a total production run of approximately 1,000 units. Collectors prioritize this reference for its blue sunray dial featuring a "shark tooth" scale, which includes vertical sub-dial markings and a tachymeter integrated into the minute track. It utilizes the high-frequency El Primero 3019 PHC automatic chronograph movement housed in a 37mm stainless steel tonneau-shaped case. On the secondary market, vintage examples typically range from $15,000 to $25,000 depending on condition and the presence of the original Gay Frères ladder bracelet. A notable production detail is its appearance on the cover of Manfred Rössler’s book on Zenith, which solidified its nomenclature. In 2020, Zenith released a modern revival edition in collaboration with Revolution & The Rake, limited to 100 pieces, which maintains high resale value.
