The watches are delivered in a spectacular box that holds an empty pillow for the next step in Zenith's evolution - a mechanical watch that measures up to 1/100th of a second. It's powered by the dual escapement caliber El Primero 9004, with a central chronograph hands that turns once every second. It is powered by the El Primero 3600, which has a central chronograph hand that turns once every 10 seconds. Zenith’s A386 reference was the vehicle of choice to debut this soon-to-be-legendary caliber. It was 1969, and the year was all about the debut of the automatic chronograph.

This is a newly designed model with a 42mm case crowned by a ceramic bezel. Either way, 50 years ago, folks in Baselworld’s Hall 1 gathered to see the brand new Zenith El Primero for the very first time.

The second watch is the Chronomaster 2 El Primero 03.3001.3600/69.C816. It has a 38mm case housing El Primero 400. The first piece is the El Primero A386 Revival 03.A386. The set consists of three watches that represent the various faces of the El Primero - vintage, classic and modern. The Zenith El Primero turned 50 in 2019 and Zenith is celebrating with this special '50 Years of El Primero' Anniversary set.
