Zenith Pilot Montre d'Aeronef Type 20

Zenith was put on the map of luxury Swiss watchmakers when they unveiled the El Primero calibre in 1969. The brilliant engineering behind the first high-frequency automatic chronograph movement found in the El Primero was almost lost forever when the company made a shift to quartz watches a few years later, but has since re-emerged as the brand’s driving innovation in the world of luxury watches.
