Zenith Defy El Primero 21 Ultrablue – Ref. 97.9001.9004/81.R946

A statement in high-frequency performance and contemporary design — the Zenith Defy El Primero 21 Ultrablue represents the cutting edge of chronograph engineering. Powered by the in-house El Primero 9004 automatic movement, this precision instrument features dual escapements — one at 5 Hz for timekeeping and another at an astonishing **50 Hz for the chronograph — enabling measurement down to 1/100th of a second.
Crafted in micro-blasted titanium for a lightweight yet durable presence, the 44 mm case showcases an openworked dial with grey counters and rhodium-plated indices coated in Super-LumiNova for superb readability. The striking blue accents on the movement and the blue “Cordura”-effect rubber strap add a bold visual identity to a technical masterpiece. Water resistant to 100 meters, this chronograph delivers performance without compromise.
