Chronomaster Solo Sport

Few movements have shaped modern watchmaking quite like the El Primero. Introduced by ZENITH in 1969 as the world’s first automatic integrated high-frequency chronograph calibre, it established a new technical standard through its 5 Hz regulating organ and quickly became one of the most recognisable movements in horology. Yet beyond the chronograph itself, El Primero has always been defined by something more fundamental: rhythm, 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, CHRONOMASTER introduces a three-hand watch built around everyday versatility while preserving the high-frequency identity that has defined El Primero for more than five decades. Freed from the chronograph display, the CHRONOMASTER Solo Sport brings attention back to what has always defined El Primero beyond measurement itself: high- frequency cadence, precision and sensation on the wrist. The result is a watch conceived not around a singular use or occasion, but around the rhythm of everyday life itself.
