In 1969, Zenith definitively put its name in the history books by presenting El Primero, the first ever integrated automatic watch, also beating at the exceptional speed of 36,000 vibrations per hour and thus displaying 1/10th second precision – an achievement that makes it the world’s most accurate series-produced chronograph to this very day. This El Primero Stratos Flyback is driven by the El Primero Calibre 405 B automatic movement built around a column wheel. While this chronograph naturally beats at the frequency of 36,000 vibrations per hour enabling 1/10th second precision, it is also equipped with a date display, a telemetric scale, and above all with the famous flyback function.
