The Zenith brand, started by Georges Favre-Jacot, has a long and impressive history in the watchmaking industry. The brand invented and safeguarded the world’s fastest and most accurate mechanical chronograph movement, the El Primero. Charles Vermot had a hand in keeping this masterful movement alive by hiding both design blueprints and mechanical parts for the El Primero when the company considered switching to quartz technology. Fortunately for avid watch enthusiasts and collectors everywhere, the brand opted to continue manufacturing the El Primero, and it is still created today. New improvements to the El Primero movement keep Zenith watches accurate and precise to this day. The contemporary collections host series like Defy, Chronomaster, Pilot, and Elite.
