The Zenith Chronomaster Sport is, at its core, a modern chronographChronograph A chronograph complication is a feature in a watch that allows the wearer to measure elapsed time in addition to telling the time. It works by having a separate set of gears and levers, called the chronograph mechanism, which is activated by pressing a button or a pusher. The chronograph mechanism starts and stops the chronograph's second hand, which is usually located on the watch's dial, separate from the regular watch hands. The elapsed time is usually displayed on a sub-dial or a register on the watch's dial. [Learn More] built for those who care deeply about precision, and just as much about presence. In recent years, it’s become something of a flagship within Zenith’s lineup: not overly nostalgic, not overly techy, but planted confidently in the middle of what a contemporary automatic chronograph should be.
I spent some limited time with both the Blue and Pink dial variants. The latter is especially difficult to find, so I figured it is worth sharing some real life images from the hands-on here – albeit a brief one.
At 41mm in diameter and 13.6mm thick, the Chronomaster Sport has settled into what many would call a modern sweet spot. Not oversized, but definitely present on the wrist, especially with the polished steel surfaces, gleaming bezels, and sunray-patterned dials. These will not go unnoticed on the wrist. The lug-to-lug is 47mm, longer than a dress watch, but balanced. It feels sporty without becoming bulky.
A quick word on the limited Chronomaster Sport “Pink”, a 500-piece release. This is part of Zenith’s ongoing effort to support breast cancer research. Valiant effort, and certainly a fantastic watch as well. If you can find one, grab one. The second is a standard (yet striking) blue-dial version with the brand’s signature tricolor subdials in grey, blue, and silver. Side by side, it’s a tough choice, but I’d say you can’t go wrong either way!
Both models feature the same case dimensions, the same sapphire crystal on both sides, and the same robust stainless-steel bracelet. And of course, the same El Primero movement. Note the similar-looking yet different bezels.

[Learn More] of Swiss horology, and with the 3600 calibre, Zenith has brought the chronograph into the 21st century without losing its soul. This automatic column-wheel chronograph beats at a high-frequency 5Hz (36,000 vph), the same fast-beating heartbeat that made the original El Primero famous.
What separates the 3600 from almost every other automatic chronograph in the world today is its 1/10th of a second measurement. The chronograph hand doesn’t just sweep, it makes one full rotation every 10 seconds, allowing each of the 100 hashmarks on the bezel to represent 1/10th of a second in real time. It also makes for a fun photography exercise if you get the shutter speed just right and capture the tick marks exactly, good fun and a perfect waste of time.
The 3600 has a full 60-hour power reserveRéserve de marche Also known as Power Reserve. A watch's power reserve refers to the amount of time a mechanical watch can run without being wound. The power reserve of a mechanical watch can vary depending on the size of the mainspring, the efficiency of the gear train, and the rate at which the mainspring releases energy. If a watch has a Power Reserve 'complication' it simply means that the status of the power reserve can be seen on the watch itself (either on the dial or movement side of the watch). [Learn More], a practical upgrade over previous generations. This is also not a small feat, given the high beat rate of this movement. The good-looking movement is visible through the transparent sapphire caseback. The column wheel is visible too (oh, and engaging the chronograph pushers offers that crisp, tactile snap that only a true column-wheel system can deliver).
The Pink version makes a powerful statement with a bold dial and charitable mission, while the blue model leans into legacy and timelessness. Both showcase the brand’s best-in-class movement and thoughtful execution. For anyone looking for a high-performance, mechanically meaningful chronograph, the Chronomaster Sport is impossible to ignore.
