Zenith's new tagline is "Master of Chronographs Since 1865" and with the impact the El Primero movement has had on watchmaking, it's a tagline they can use proudly. The book on the El Primero continues to be written and the latest chapters in that story are the revamped Chronomaster Open and the latest version of the Chronomaster Sport. The redesigned Chronomaster Open (above - $10,000-$21,300) makes its debut with a 39.5mm case in steel or rose gold and rethinks the signature three-counter array with a hesalite crystal element that gives you a view of the movement through the dial while also maintaining the design's signature look. Powered by an El Primero 3604, the automatic movement has a power reserve of 60 hours.
The company has also updated its Chronomaster Sport ($12,800-$38,200) line with a trio of new gold models and our favorite, a Boutique Edition with a tri-colored ceramic bezel. This bezel joins a combination of grey, anthracite, and blue to match the colors of the chronograph counters. The watches feature 41mm cases, a matching bracelet, and the El Primero 3600 automatic movement with a 60-hour power reserve.
