The Chronomaster Sport 65.3104.3600/52.C920, seen from the bench

The Zenith Chronomaster Sport 65.3104.3600/52.C920 is a contemporary reinterpretation of the legendary A385, the first automatic chronograph with column-wheel movement launched in 1969. The 41mm case combines stainless steel and black ceramic, delivering structural solidity and scratch resistance. Equipped with the El Primero 3600 caliber beating at 36,000 vibrations per hour, it offers chronograph precision of one-tenth of a second. The integrated 20mm lug width ensures optimal proportions and structural coherence.
