a few subtle nods to the historical version of the El Primero 1969

These attributes are inherited from its illustrious predecessor, the world’s most accurate series-produced chronograph developed by Zenith in 1969. This complete opening enables clients to grasp and visually appreciate the high frequency of the movement, the signature of the legendary El Primero integrated automatic column-wheel chronograph calibre with its 326 components (including 31 jewels), beating at the swift pace of 5 Hz (36,000 VpH) and thus capable of measuring and displaying the time with tenth-of-a-second precision. The latter is the most modern and contemporary interpretation, representing THE major new launch of 2017. To ensure a better understanding of the fundamentals governing its flagship Chronomaster collection, Zenith offers its legendary El Primero chronograph in three different versions: with an entirely solid (closed) dial, a half-open (Open) dial, and now an entirely open (Full Open) dial.

Providing an unobstructed view of its legendary mechanism, the famous automatic Zenith Chronomaster El Primero “Full Open” is aptly named, since it can now reveal the heart of its performance and precision thanks to a dial that is now entirely open – and openworked.
