Zenith Defy El Primero 21 Ultrablue

The Defy 21 El Primero Ultrablue showcases Zenith's revolutionary dual escapement system in a striking 44mm microblasted titanium case. This chronograph measures time to 1/100th of a second with its central hand completing one full rotation per second - talk about precision timing! The grey openworked dial reveals the blue-colored El Primero Caliber 9004 movement beneath, featuring 293 components and 53 jewels working in perfect harmony. With its dual frequency system running at 36,000 vph for timekeeping and an incredible 360,000 vph for chronograph functions, this TIME LAB Chronometer certified piece delivers Swiss accuracy you can see in action. The 30-minute counter at 3 o'clock, 60-second counter at 6 o'clock, and small seconds at 9 o'clock provide excellent readability, while the power reserve indicator at 12 o'clock keeps you informed. The blue fabric-effect rubber strap perfectly complements the movement's blue details, creating a cohesive sporty-luxe aesthetic that works from boardroom to weekend adventures.
