The El Primero 03.2080.400/01.C494, seen from the bench
The Zenith El Primero 03.2080.400/01.C494 is a 42mm stainless steel chronograph powered by the legendary El Primero 400B calibre, which beats at 36,000 VPH—triple the frequency of standard movements. Launched in 1969, it was the world's first integrated automatic chronograph and remains a horological milestone. The 20mm lug width accommodates the case proportions perfectly, while the column-wheel chronograph mechanism delivers tenth-of-second precision with fluid mechanical response.
