A reinterpreted version of the ZENITH A386, one of the first round-cased steel El Primero reference from 1969, the Chronomaster Original now reinterprets the iconic tricolour dial in black – a first for the historical 1969 case. Equipped with the latest generation of the El Primero high-frequency automatic chronograph calibre that features a 1/10th of a second chronograph function, the Chronomaster Original with black tricolour dial stands out as a thoroughly contemporary take on one of the most emblematic El Primero references.
