In 1969, a frequency of 36,000 vibrations per hour was unheard of for a mechanical movement. Here, you will discover the fascinating story of the Zenith El Primero movement.
Zenith El Primero is a unique phenomenon in the world of watchmaking. This movement is considered one of the most important and well-known in horology. Watch connoisseurs know about this movement, and you should too. After all, it played a key role in the history of watchmaking.
El Primero became the foundation for many iconic watches and gained greater recognition than many models with this movement. If you speak with any watch collector, they will surely remember this movement. Even if they don't own such watches, they will name at least one or two models with this movement.
In this article, we will take an in-depth look at the El Primero watches and their famous movement. This will help you truly appreciate Zenith's contribution as a watchmaker and movement manufacturer.
For some reason, the industry does not value Zenith as highly as it should. It can easily be placed alongside brands like Rolex, Patek Philippe, and Audemars Piguet.
Brief History of Zenith El Primero
Imagine opening your first watch production at the age of 22. That is exactly what Georges Favre-Jacot did.
In the picturesque Swiss town of Le Locle, he founded a workshop that later became a world pioneer.
The brand's 100th anniversary was marked by the release of El Primero - the world’s first automatic chronograph.
At that time, many watch companies, including Seiko, were striving to create a similar movement. In 1969, self-winding technology had not yet been used in watches with a stopwatch function.
Zenith outpaced its competitors.
The El Primero movement, which translates from Spanish as "The First," set new standards for chronometry accuracy. It became a record holder with a frequency of 36,000 vibrations per hour.
A deviation of only +5/-3 seconds per day allowed for timekeeping accuracy to 1/10 of a second. For its time, this was a revolutionary achievement, promising unprecedented precision for automatic watches.
Zenith El Primero Movement
We have found that Zenith solved one of the most complex technical challenges in the history of watchmaking. Now let's see how the movement reached the market.
In 1969, Zenith introduced the Ref. 369 model with a striking "panda" dial. Then came the tricolor Ref. A386 with blue, gray, and silver counters. The 38 mm case diameter made these chronographs perfect for slender wrists.
In the same year, the mass-market quartz movement appeared, led by Seiko and their famous Astron model. Despite the quartz crisis, Zenith managed to survive.
In 1998, Rolex turned to Zenith for an automatic movement for the legendary Daytona. The company replaced the caliber 4030 with the existing manual-wind movement. This sports model became one of the most coveted among collectors.
The movement is also used in some TAG Heuer Monaco and Carrera models, as well as in Hublot Spirit of Big Bang. Moreover, Bvlgari Octo Velocissimo Chronograph and Panerai OP IV benefited from the high precision of El Primero.
After reviewing the movement, let's look at Zenith El Primero watches that are of interest for investment.
