Defy El Primero 21

This Zenith Defy El Primero 21 reference 95.9005.9004/01.R782 is a technically groundbreaking certified pre-owned luxury watch, offered in very good condition and delivered as a full set with its original box and papers. A flagship of modern high-frequency chronograph innovation, this model showcases Zenith’s mastery of extreme precision and contemporary design.

The watch features a 44 mm case crafted from titanium with ceramic components, combining lightness, strength, and a distinctly modern aesthetic. The openworked skeleton dial reveals the remarkable architecture of the movement, allowing a clear view of the high-speed chronograph mechanism. Bold hands and applied markers ensure strong legibility despite the open design. The watch is fitted with a rubber strap, enhancing comfort and reinforcing its sporty, technical character.

Powering this timepiece is the Zenith El Primero Calibre 9004, an in-house automatic chronograph movement engineered to measure time to 1/100th of a second. It features two independent escapements: one beating at 36,000 vibrations per hour for standard timekeeping and a second running at an extraordinary 360,000 vibrations per hour dedicated to the chronograph. The movement delivers a power reserve of approximately 50 hours for the main timekeeping function, combining extreme precision with solid everyday usability.

This example is presented in very good overall condition, showing only light signs of careful wear. The case, dial, crystal, and rubber strap are well preserved, maintaining the watch’s strong and technical appearance.

Delivered with its original Zenith box and original papers, this pre-owned Zenith Defy El Primero 21 represents an exceptional opportunity to acquire one of the most advanced mechanical chronographs available today.
