Affectionately called the “Cover Girl” a name that stuck following the appearance of the timepiece on the cover of Manfred Rossler's book – Zenith: Swiss Watch Manufacture since 1865, the A3818 was first introduced in 1971 for a brief period of time. This short exposure to the public eye made it become one of the most coveted and exclusive vintage El Primero watches.
Keeping this exclusivity in mind, Zentih and Revolution brings back the sporty chic, immensely sought-after “Cover Girl” in a limited-edition Revival series of 100 pieces.
