As its first 2021 debut, Zenith launches Chronomaster Sport, an evolution of the bedrock Chronomaster, the Le Locle watchmaker’s most direct link to its historic El Primero automatic chronograph, which debuted in 1969.
Already sporty in its historical guise, the new 41mm steel Zenith Chronomaster Sport more directly –and boldly – displays its split-second timing abilities with the added utility of a wide black ceramic bezel etched with 1/10-of-a-second measurement marks.
The new bezel enhances the visibility of the timing function, linked to the El Primero’s 36,000 vph frequency, beyond even the clean black ceramic bezels found on the existing Zenith Chronomaster 2 limited edition references. As far as we’re aware, the new Chronomaster Sport is the only production sport watch that offers a 1/10-of-a-second timing scale linked to its central chronograph hand. When activated, the hand rotates once around the dial in ten seconds.
To underscore the robust nature of the new Chronomaster Sport, Zenith here uses the El Primero 3600, the movement Zenith debuted in that earlier Chronomaster 2. The caliber, with a newly blued column wheel and “new architecture,” is more efficient than earlier El Primeros, according to Zenith, and offers a higher power reserve, now rated to sixty hours. Zenith has affixed a new skeletonized rotor to the movement, visible through a clear sapphire caseback.
The new dial
In addition to adding a wide ceramic bezel with 1/10-of-a-second scale to the front side of the new Chronomaster Sport, Zenith has also enhanced the collection’s dial and bracelet to differentiate it from previous Chronomaster offerings.
Both dial options, matte white and black, appear to contrast more starkly with the three subdials. The steel case, with familiar pump-style pushers, now links to an integrated steel bracelet similar to those conceived by Gay Frères, which has historically supplied many of Zenith’s metal bracelets. Zenith also offers a sharp-looking blue or black rubber strap option with a steel deployant buckle.
As noted, Zenith is offering the Chronomaster Sport with either a white dial or black dial in two references. Whether the black or matte white dial, both with signature El Primero tri-color chronograph registers are blue, anthracite and light grey, each graduated to sixty.
