Zenith Defy Anniversary Limited Watch

In 1969, the fastest chronograph movement in the history of mechanical watch manufacturing was born. It was the El Primero 400 manufactured by Zenith. This high-precision movement certified by the Observatory has reached an unprecedented high frequency-36,000 times per hour, and it can accurately count 1/10 seconds. At the same time, on this basis, the brand also successfully launched a calendar, flyback timing, and even a complex tourbillon. El Primero’s reliability makes the brand’s styles with basic timing functions based on it, and it remains a strong technical product for the brand for 40 years. In 2009, a whole series of watches decorated with brand color bars was released, marking the 40-year journey of El Primero in the watch industry.
