This certified pre-owned Zenith Defy El Primero 21 ref. 95.9002.9004/78.R584 captures the full spirit of Zenith’s avant-garde engineering and its legendary high-frequency chronograph mastery. As part of the Defy collection, this model combines cutting-edge materials, architectural design, and one of the most innovative movements ever produced by the manufacture. The 44 mm brushed titanium case delivers exceptional lightness and durability, offering a bold presence on the wrist without compromising comfort.
Its openworked dial showcases the spectacular mechanics beneath, revealing the dual-escapement El Primero 21 calibre—one escapement beating at 36,000 vph for timekeeping, and a second at a remarkable 360,000 vph dedicated to the chronograph. This architecture enables the chronograph to measure time to 1/100th of a second, placing the Defy El Primero 21 among the most advanced mechanical chronographs available today. The watch is paired with a high-quality rubber strap, ensuring a modern, sporty, and secure fit.
This example is offered in very good condition, with its titanium case and skeletonised components preserved in excellent shape. It includes the full set, with original box and papers—an essential asset for collectors seeking a certified pre-owned luxury watch with full provenance. Dynamic, technically superior, and unmistakably contemporary, the Defy El Primero 21 is a standout choice for enthusiasts of innovative horology.
