The Zenith El Primero is one of the most important chronograph movements in watchmaking history.
Introduced in 1969, the El Primero was among the first automatic chronograph calibres.
Zenith El Primero watches combine technical innovation with classic chronograph styling and appeal to collectors seeking mechanical credibility alongside distinctive design. The El Primero stands out with its high-frequency precision of 36,000 vibrations per hour, enabling 1/10th of a second measurement.
Launched in 1969, the El Primero was one of the first automatic chronograph movements ever produced and one of the very few to remain in continuous production to this day.
Developed entirely in-house, it represented a major technical achievement, combining automatic winding with an integrated chronograph mechanism rather than a modular design.
Its high-beat architecture, operating at 36,000 vibrations per hour, allowed for improved timing precision and the ability to measure elapsed time to 1/10th of a second - a feature that still distinguishes it from many competing chronographs.
The movement’s reputation was further strengthened in the late 1980s when it was selected as the base calibre for early automatic Rolex Daytona models, underlining its reliability and performance credentials.
Over the decades, Zenith has continued to refine and evolve the El Primero, introducing updated materials, enhanced power reserves and modern finishing while preserving its original high-frequency DNA. Today, the El Primero remains central to Zenith’s identity, forming the backbone of the Chronomaster collection and numerous limited editions, and standing as one of the most respected chronograph movements in watchmaking history.
Explore a curated selection of used Zenith El Primero watches, including stainless steel, two-tone and precious metal references. From vintage A386-inspired models to modern Chronomaster editions, each El Primero reflects Zenith’s long-standing expertise in high-beat chronograph manufacturing.
Buying a pre-owned Zenith El Primero provides access to one of the most respected automatic chronograph movements at a more accessible entry point than purchasing new. The UK secondary market often includes discontinued references and heritage reissues that are no longer widely available.
The El Primero movement’s high-frequency 36,000 vibrations per hour allows for precise 1/10th of a second measurement in modern versions, reinforcing its reputation for technical excellence.
