Zenith El Primero celebrates its 50th anniversary

El Primero, the first automatic movement capable of measuring tenths of a second celebrates its 50th anniversary.

In 1962 at Zenith, the idea of launching an automatic chronograph took root. There was no automatic chronograph on the market at the time. In 1969, Zenith made its stellar contribution to the chronograph saga with the El Primero (meaning ‘the first’ in Esperanto): an integrated automatic column-wheel mechanism beating at the high frequency of 36,000 vibrations/hour (5Hz) enabling it to reach chronometer-certified tenth of a second precision. It is to this day the world’s most accurate series-made chronograph.
