For Zenith, “Master of Chronographs” is a testament to the manufacture’s illustrious past and its countless achievements that contributed to the advancement of mechanical chronographs for over 50 years. In particular, it highlights Zenith’s commitment to the pursuit of perpetual innovation when it comes to watchmaking’s most complex and sought-after complications. Since the launch of the revolutionary El Primero calibre in 1969 as the world’s first automatic high-frequency integrated chronograph movement, Zenith has maintained and cultivated its spirit of innovation without ever ceasing break new boundaries and offer even greater levels of precision and performance. It has mastered not only the automatic chronograph, but also the fractional measurement of time by offering 1/10th and 1/100th of a second high-frequency calibres.

With 2021’s introduction of the new and improved El Primero 3600 that boasts a 1/10th of a second chronograph function and improved efficiency, the time had come to adapt and incorporate the latest developments into the emblematic Chronomaster Open. More than a simple facelift, the new Chronomaster Open is imbued with the lines and attributes of the latest generation of the Chronomaster collection. Somewhere between the sleek
sportiness of the Chronomaster Sport and the historically inspired Chronomaster Original for a modern distillation of the essential Zenith El Primero chronograph.

Revisiting the iconic tri-colour dial configuration that debuted with the iconic A386 in 1969 and which remains a distinctive and instantly recognizable El Primero design element, the latest iteration of the Chronomaster Open retains it entirely with a transparent twist inside a more slender 39.5mm case. Instead of cutting out the small seconds counter at 9 o’clock entirely as was the case with the previous versions of the Chronomaster Open, the three counter colours are retained thanks to a hesalite crystal element that serves as a readable sub-dial while allowing a view of the silicon star-shaped escape wheel. The opening itself has also been reinterpreted, foregoing the former version’s applied “frame” and instead opting for circular openings with chamfered edges, revealing the movement with more straight bridges and a more contemporary grey tone.
