Chronomaster

The Zenith Chronomaster El Primero Open, reference 03.2040.4061/01.C494, is a striking interpretation of Zenith’s legendary chronograph, combining classical Chronomaster design with an open dial that reveals the high-frequency heart of the El Primero. This certified pre-owned luxury watch is presented in very good condition and is offered as a full set with original box and papers.

Housed in a 42 mm stainless steel case, the watch delivers a refined yet sporty wrist presence, enhanced by polished and brushed finishes. The silver-toned dial is distinguished by its iconic open aperture at 10 o’clock, offering a direct view of the escapement and highlighting Zenith’s technical mastery. The tri-compax chronograph layout remains perfectly balanced, with applied hour markers and faceted hands filled with luminous material ensuring excellent legibility. A discreet date window completes the dial without disrupting its symmetry.

At the heart of the watch beats the legendary Zenith El Primero Calibre 4061, an automatic high-frequency chronograph movement operating at 5 Hz (36,000 vibrations per hour). This calibre is capable of measuring time to 1/10th of a second and is renowned for its precision, robustness, and historical significance. It delivers an approximate 50-hour power reserve and can be admired through both the open dial and the sapphire crystal case back.

The watch is fitted with a black leather strap, reinforcing its elegant character while ensuring comfort for everyday wear. Sapphire crystal protects the dial, offering excellent scratch resistance and long-term clarity.

This pre-owned Zenith Chronomaster El Primero Open, reference 03.2040.4061/01.C494, represents an excellent opportunity to acquire a technically expressive pre-owned luxury watch that combines iconic chronograph performance with a distinctive open-dial aesthetic.
