The El Primero 10.2260.400/69.R573, seen from the bench
The Zenith El Primero 10.2260.400/69.R573 is the contemporary evolution of the first integrated automatic chronograph, born in 1969. The El Primero 400B Titanium caliber beats at 36,000 alternations per hour, an unmatched standard among mainstream automatic chronographs. The 45mm case combines carbon and aluminum for reduced weight while maintaining structural rigidity, featuring hours, minutes, small seconds, date, and a column chronograph. The 20mm lug width is precisely proportioned to the case mass, ensuring visual harmony without sacrificing strap area.
