Introduction
Arguably one of the most famous chronograph makers in all of horology, Zenith is best-known for their El Primero automatic chronograph movement. From its status as one of the first automatic chronograph movements ever made (depending on who you ask) and the base movement to feature within the second-generation Rolex Daytona, the El Primero is certainly a modern-day icon. Launched in 1969, its incredible hi-beat rate, amazing accuracy and technical prowess ensured that any watch it was inside was one of the best chronographs money could buy. Offered here we have the Zenith Chronomaster Sport that was debuted in 2023 with a slew of modern design elements that have been combined with heritage-based elements to create a watch that appeals to modern collectors’ requirements for a luxury timepiece while speaking to thoughtful design. As such, the Chronomaster features either a black dial (as opposed to black or silver options that debuted in 2021) with tri-color subdials as Zenith pioneered decades ago, pump-style chronograph pushers and their legendary El Primero chronograph movement that can measure to 1/10th of a second. In addition to that, this timepiece sports a stainless steel 41mm case, a stainless steel bezel and a robust stainless steel bracelet that can safely tackle any wear and tear - as modern collectors have come to expect.

THE DIAL
Featuring a blue dial, the Chronomaster's grey, silver, and dark navy tri-color subdials stand out all the more with their concentric guilloche engraving and stepped design.

THE CONSTRUCTION
As in keeping with modern requirements, the Chronomaster's 41mm stainless steel case wears fantastically on the wrist with its 13.8mm height ensuring that it wears compact for a high-frequency chronograph that features a date function and exhibition caseback.

Our Perspective
A legendary piece of the watchmaking industry in ways that not many watches can compete with, the El Primero movement has become an industry icon that requires a special watch to do it justice, and the Chronomaster succeeds in showcasing its legendary status. Launched in 2023 with some updates, such as its new blue dial and steel bezel replacing the ceramic bezel on its siblings, this is one stylish and historically important watch.
