Zenith Chronomaster Original Steel 38mm Slate-Grey Dial 03.3400.3610/39.C910 - BRAND NEW Zenith Chronomaster Original Steel 38mm Slate-Grey Dial…

The Zenith Chronomaster Original 03.3400.3610/39.C910 represents one of the most historically significant and collectible chronograph watches available for sale today. Zenith introduced the Chronomaster line as a direct heir to the El Primero legacy — a movement widely recognized as one of the first automatic chronograph calibers ever brought to market, debuted in 1969. The Chronomaster Original collection was designed to honor that heritage faithfully, reinterpreting the iconic tri-color sub-dial layout and vintage proportions for a modern audience while remaining true to the spirit of the original.

At 38mm in stainless steel, this reference occupies a sweet spot that many collectors actively seek: large enough to command attention on the wrist yet compact enough to slide effortlessly beneath a shirt cuff. The case is crafted in polished and satin-brushed stainless steel, delivering the kind of refined two-tone surface texture that distinguishes a dress-sport watch from the crowd. The stainless steel bezel complements the case with understated elegance, keeping the focus squarely on the dial.

The slate-grey dial is the visual centerpiece of this reference. Slate grey is a sophisticated, neutral tone that reads differently under various lighting conditions — appearing almost charcoal in shade and lifting to a cooler, silvery hue in direct sunlight. Brown indices add a warm vintage contrast against the cool grey ground, lending the dial a layered, collectible character. The tri-register sub-dial layout — a Chronomaster signature — sits at the 6, 9, and 12 o'clock positions, each in a subtly differentiated color that echoes the celebrated original El Primero dials of 1969.

Powering the Chronomaster Original is Zenith's automatic chronograph movement, the direct descendant of the storied El Primero caliber. This movement is renowned among horological enthusiasts for its high-frequency oscillation, which allows the chronograph to measure elapsed time with exceptional precision — a technical distinction that sets Zenith apart from many competitors in the luxury sport-watch segment. The movement is visible through a sapphire exhibition caseback, inviting the wearer to appreciate the craftsmanship within.

The watch is presented on a leather strap that reinforces its vintage-inspired identity, providing everyday comfort while keeping the aesthetic cohesive. Whether worn to a formal occasion or a weekend outing, the Chronomaster Original adapts naturally to its environment. This reference ships brand new, complete with box and papers, giving the buyer full confidence in provenance and warranty coverage.
