The El Primero 03.2410.4010/21.C722, seen from the bench
The Zenith El Primero was introduced in 1969 as the first automatic high-frequency chronograph movement. It is powered by the El Primero Calibre 4010 with functions of hours, minutes, small seconds, big date and chronograph with column-wheel. The 03.2410.4010/21.C722 reference represents one of the contemporary variations of this technical collection.
