Editor's notes

The CHRONOMASTER El Primero A384 Revival is a faithful reproduction of the very first ZENITH watch in steel to feature the El Primero high-frequency automatic chronograph calibre from 1969. The tonneau shaped case and panda dial are perfectly recreated using the original production plans. Paired with a black alligator leather strap.
