Few movements have shaped modern watchmaking quite like El Primero. Introduced by Zenith in 1969 as the world’s first integrated automatic high-frequency chronograph caliber, it set a new technical standard thanks to its 5 Hz regulating organ.

Yet, beyond the chronograph function itself, El Primero has always been defined by something more fundamental: the rhythm, the cadence, and the unique sensation of high-frequency precision. With the Chronomaster Solo Sport, Zenith explores this dimension through a more direct and essential interpretation of the collection. For the first time, the Chronomaster line introduces a three-hand watch designed for everyday versatility, while preserving the high-frequency identity that has defined El Primero for over five decades.
