The El Primero 03.2050.4026/91.C630, seen from the bench

The Zenith El Primero 03.2050.4026/91.C630 perpetuates the revolutionary legacy of the first integrated automatic chronograph launched in 1969, featuring the El Primero 4026 movement operating at 36,000 alternations per hour. The 44mm stainless steel case houses hours, minutes, small seconds, date and chronograph with column wheel and rattrapante mechanism for split-second measurements. The 20mm lug width is precisely determined by the case geometry and attachment points.
