Zenith Chronomaster Open SS Black Dial 2025

The Zenith Chronomaster Open reference 03.3300.3604/21.C822 is a modern chronograph designed for collectors who want the El Primero story on full display, not hidden behind a conventional dial. Introduced in 2022, this 39.5mm stainless steel piece pairs a matte black openwork-style presentation with tricolor character in the counters and a transparent running-seconds window. Power comes from the Zenith El Primero 3604 automatic chronograph movement, engineered for high-frequency precision with a 60-hour power reserve. The watch delivers classic Chronomaster functionality with chronograph timing plus small-seconds style presence on an uncluttered layout that emphasizes legibility. Finished with a black cordura-effect rubber strap, it wears with strong sport-couture versatility while staying firmly in the Zenith chronograph design language. At 100 meters water resistance, it is positioned as a serious daily-wear chronograph rather than a display-only novelty. For buyers and enthusiasts, the open configuration adds both visual depth and mechanical intimacy, making this reference a compelling alternative to fully masked-dial chronographs. With the El Primero 3604 as its beating heart, it also carries one of the most celebrated modern automatic chronograph lineages in contemporary horology.
