Zenith Chronomaster Solo Sport

Zenith’s El Primero movement, introduced in 1969 as the world’s first automatic integrated high-frequency chronograph calibre, is famously associated with the world’s most precise chronographs.  In the new Chronomaster Solo Sport—freed from the measurements of a chronograph display—attention returns to El Primero’s 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.

Its 40mm stainless steel case balances compact proportions with a strong architectural presence on the wrist, while the ceramic unidirectional rotating bezel introduces a more functional and contemporary tension within the silhouette. Framed by dynamic crown protectors, the screw-down crown reinforces the watch’s robust construction and contributes to its 20 ATM water resistance.

At the heart of the watch beats the El Primero 3620 calibre. Equipped with a silicon escapement, a stop-second mechanism, and a bi-directional winding system with a star-shaped rotor, it delivers 60 hours of power reserve. The dial plays a central role in expressing high frequency visually. Crafted from ceramic, its structured surface is built around a motif evoking the rhythm and vibration of the movement beneath. This new pattern was conceived as a true visual signature of high frequency. The same visual identity extends to the seconds hand counterweight, while the shark tooth minute track introduces a highly segmented reading of time inspired by historical Zenith references. Together, these elements create a dial architecture that feels unmistakably tied to the world of El Primero.

The Chronomaster Solo Sport is presented on a steel bracelet with a micro-adjustable Zenclasp™ closure. The watch is available in three versions with ceramic dials and bezels in black, white and brown, featuring hours, minutes, seconds and date indications. The black version is also offered in a no-date variant.
