The El Primero 95.3001.3600/69.C817, seen from the bench

The Zenith El Primero 95.3001.3600/69.C817 represents the chronograph tradition of Zenith, rooted in 1969 with the first high-frequency automatic movement. This model combines titanium and ceramic construction for reduced weight without sacrificing structural rigidity. The El Primero 3600 caliber beats at 36,000 alternations per hour, enabling one-tenth second measurement on a column-wheel chronograph. The 42mm case integrates mechanical complexity with a ceramic outer ring for thermal stability and titanium chassis for rigidity. Features complete chronographic functions with integrated counters, a strategically positioned date window, and a 20mm lug width.
