The chronograph, one of the most sought-after watch complications, is something Zenith has mastered for over 50 years. It’s El Primero calibre, the world’s first automatic, integrated high-frequency chronograph movement, was nothing short of revolutionary when it was first unveiled in 1969. Today, this unique legacy lives on through the Chronomaster line, which has evolved to include a number of different designs and, a world-first at the time of its release, a partially open dial revealing the beating heart of the El Primero. The Revival series are literal reproductions of iconic Zenith chronograph watches from the 1960s and 1970s, safeguarding the exact some proportions and looks, as well as the venerable El Primero calibre.
