Nevertheless, the A384 and A385 models are equally attractive and, possibly, even more representative of the era when the El Primero movement was launched. All of them, with their own distinctive design, can be named вЂњemblematicвЂќ вЂ“ with a special mention for the A386, which has gained an indisputable cult status in auction rooms. ThereвЂ™s no denying the actual beauty of the watches from the 1969 El Primero trilogy. Upon landing, the watch was still functioning perfectly. Something to be notedВ about the A385 in 1970, it took part in ZenithвЂ™s вЂњOperation Sky.вЂќ This extreme test consisted of strapping the watch to an Air France Boeing 707вЂ™s landing gear on a flight from Paris to New York to test its resistance to external aggressions such as drastic temperature fluctuations, wind force and changing air pressure. Mechanically, there was no difference between the watches from the trilogy, as all were using the same El Primero movement. Based on the same case as the A384, meaning a 37mm cushion-shaped block of steel, it stood out thanks to its dial, with a warm colour and, something new for the industry, a dГ©gradГ© smoked effect вЂ“ according to Zenith, this was вЂњ the first smoked dial ever to be made in the watch industryвЂќ (something that would need to be verifiedвЂ¦) While the two other watches in the trilogy were a bit more classic in their design, the A385 was bold. The El Primero A385 is a very distinctive watch.

It has seen the introduction of the worldвЂ™s first automatic high-frequency chronograph, the El Primero. Together with 1865 (the year the brand was created), 1969 is, without doubt, the most important year in ZenithвЂ™s history. But in 1969, three manufactures will unveil their own vision of the automatic chronograph вЂ“ namely Zenith with the El Primero, Seiko with the Calibre 6139 and theВ Chronomatic/project 99 consortium uniting Heuer-LГ©onidas SA, LГ©on Breitling SA, Hamilton-BГјren and chronograph specialist DГ©praz & Co with theВ Calibre 11.ДЄ copy of an old Zenith catalog, showing the 1969 вЂњEl Primero trilogyвЂќ Surprisingly, before the introduction of not one but three of these architectures, all chronograph movements were hand-wound.

Thus, if we mention the year 1969, it should give you an indication of what the rest of the article should be aboutвЂ¦ 1969 has been a year of innovation for the whole industry, but also for Zenith.

Now, in 2021, the brand gives the last and third model its moment of glory, with the new Zenith Chronomaster Revival A385. Last year, it was time for the panda watch, the A384, to be re-edited.

In 2019, for its 50th-anniversary, Zenith commemorated this legendary calibre with multiple вЂњRevivalвЂќ editions of the A386 model, the most sought-after watch in the 1969 trilogy. With its column-wheel architecture, its high-frequency, and multiple small but necessary upgrades, it has managed to stand the test of time.

Even after more than 50 years of loyal services, the El Primero remains one of the most fascinating movements to be manufactured.
