Introduced in 1969, the **Zenith El Primero** was the world’s first fully integrated automatic chronograph with a high-beat movement running at 36,000 vph, allowing precise timing to 1/10th of a second—a breakthrough in watchmaking.  Unlike modular chronographs of its time, El Primero combined all functions into a single, compact movement. During the quartz crisis, production stopped, but watchmaker Charles Vermot secretly saved the plans and tools, making its revival possible in the 1980s. El Primero later earned even more respect when Rolex used it in the Daytona. Today, it remains a symbol of Zenith’s technical mastery, precision, and heritage. We are proud to offer this authentic Zenith El Primero chronograph wristwatch, reference 18.2045.400/57.C494.
