The Chronomaster Original 03.3200.3600/21.M3200, seen from the bench

The Zenith Chronomaster Original 03.3200.3600/21.M3200 embodies contemporary horological heritage centered on the legendary El Primero caliber, the first high-frequency automatic chronograph (36,000 vph) launched in 1969. The stainless steel 38mm case features a clean black dial with white counters, showcasing the column-wheel chronograph mechanism with independent, repeatable actuation. Equipped with the El Primero 3600 movement offering hours, minutes, small seconds, date, and chronograph functions, this model delivers decimal chronograph measurement to one-tenth of a second. The 20mm lug width ensures proper visual balance with aftermarket straps.
