ZENITH is now adding its signature colour to the dial of its most popular modern El Primero chronograph, the Chronomaster Sport. More than just a dial change however, the newest version of the Chronomaster Sport also takes a page from the “DeLuca” and “Rainbow” references of the 1980s and 1990s with a blue dial and polished steel bezel.

Winner of the 2021 Grand Prix d’Horlogerie de Genève “Chronograph” prize, the Chronomaster Sport is the culmination of ZENITH’s unrivaled legacy in crafting automatic high-frequency chronographs. Pushing the boundaries of high-frequency precision, it features a 1/10th of a second chronograph function, with the elapsed time graduated over 10 seconds on the bezel. Sporty, contemporary and unmistakably a ZENITH El Primero, the Chronomaster Sport now comes in an all-steel exterior with a striking blue tricolour dial.

Featuring elements inspired by the most emblematic El Primero references and even ZENITH chronograph references produced before the calibre’s introduction in 1969, the Chronomaster Sport with blue dial heavily draws inspiration from two particular El Primero references: the “DeLuca” from the late 1980s and the “Rainbow” of the early 1990s. For the first time in the Chronomaster Sport steel core collection, the engraved 1/10 th of a second bezel on top of the 41mm steel case with pump-style pushers is crafted in stainless steel instead of ceramic. With its polished surface and black filled engraved markers, it takes on a decidedly retro look, recalling those older El Primero models. The three-link steel bracelet with adjustable clasp completes the sporty-chic look.

Metallic blue with a sunburst finish, the dial of the newest Chronomaster Sport masterfully blends contrasts, textures and depths. And yet, it is not out of historical context. Both the DeLuca and Rainbow were made with blue dial options. One of the most iconic El Primero design features – the tricolour dial – is highlighted in a new context. The chronograph counters in shades of grey and blue are as outstanding as ever, with a difference in tone and finish between the blue counter and the blue dial. The date wheel has also been matched to the dial.

The latest in a long line of ZENITH chronographs that have raised the bars of performance and precision, the Chronomaster Sport is equipped with the latest version of the El Primero calibre, dubbed the El Primero 3600. With its high frequency of 5 Hz (36’000 VpH), the movement offers a true 1/10th of second indication. Its autonomy has also been rendered more efficient, with an extended power reserve of 60 hours. The sapphire display back provides an unobstructed view of the movement’s contemporary, architecture features a sleeker and more open design, revealing a blue column wheel and open rotor marked with the five-pointed star Zenith.

The Chronomaster Sport in steel with blue dial joins the core collection and is available at ZENITH boutiques as well as authorized ZENITH retailers around the world.
