The Chronomaster Sport 18.3101.3600/21.M3100, seen from the bench
The Zenith Chronomaster Sport 18.3101.3600/21.M3100 in rose gold evolves the legendary El Primero, history's first automatic chronograph from 1969. Powered by the El Primero 3600 caliber beating at 10 Hz for centesimal precision, this 41mm rose gold case with 20mm lug width combines bicolor ceramic bezel, column-wheel chronograph mechanism, and 50+ hour power reserve. The refined construction, visible through the sapphire caseback, includes anti-reflective crystal, screw-down crown rated to 100m water resistance, and 5N rose gold case resistant to oxidation.
