Zenith El Primero Sport emphasises the dynamic vocation that characterises the chronograph type: it has a steel case with an important diameter of 45 millimetres, water resistance to 20 atmospheres and a tachometric scale on the flange. The company offers it in two dial colours (silvered and slate) in three variants: with a dark brown alligator leather or rubber strap, and with a steel bracelet. Inside beats the automatic El Primero 400 B calibre, with column-wheel chronograph functions and the famous frequency of 36,000 vibrations per hour, shown to view through the sapphire glass back.
