The Chronomaster Original 03.3200.3600/52.C910, seen from the bench

The Zenith Chronomaster Original 03.3200.3600/52.C910 continues a legendary lineage rooted in 1969, when the El Primero calibre revolutionized automatic watchmaking with the first hundredth-of-a-second measurement at 36,000 vibrations per hour. This model features a 38 mm tonneau stainless steel case and houses the El Primero 3600 movement, enabling chronographic timing in hundredths of a second. The 20 mm lug width accommodates straight lugs, offering strap versatility while maintaining the original 1969 spirit.
