Zenith Chronomaster Open Steel 39.5mm Black Dial 03.3300.3604/21.C822 - BRAND NEW Zenith Chronomaster Open Steel 39.5mm Black Dial…

The Zenith Chronomaster Open 03.3300.3604/21.C822 represents one of the most compelling expressions of horological transparency available in modern watchmaking. Zenith introduced the Chronomaster line as a tribute to the legendary El Primero movement — widely recognized as one of the world's first automatic chronograph calibers — and the Open variant takes that heritage a step further by revealing the beating heart of the watch through an aperture cut directly into the dial. This is a watch that does not simply tell time; it invites you to witness how.

At 39.5mm, the stainless steel case of this reference occupies a sweet spot that appeals to purists who prefer a slightly more restrained diameter without sacrificing presence on the wrist. The case proportions are elegant and wearable across a wide range of occasions, from business settings to weekend leisure, and the polished and brushed finishing typical of the Chronomaster line adds a premium tactile quality that photographs rarely capture fully.

The black dial with index markers delivers maximum legibility and a timeless aesthetic. The dark backdrop creates a dramatic contrast that makes the open-worked aperture — through which the movement's oscillating components can be admired — even more visually arresting. The stainless steel bezel complements the case material seamlessly and maintains the watch's clean, unified identity.

The fabric strap supplied with this reference adds a sporty and contemporary dimension to what is otherwise a classically inspired chronograph. It is lightweight, breathable, and contributes to an overall wearing experience that is relaxed and casual without diminishing the watch's prestige. For collectors who own multiple straps or who prefer variety, the Chronomaster Open pairs well with leather, rubber, and bracelet alternatives.
