About this watch

The Zenith Defy El Primero 21 Chroma is a masterpiece of horology, boasting a bold and dynamic design with a skeleton dial that showcases the intricate workings of its impressive movement. The titanium and ceramic materials provide a modern and edgy look, while the rounded case shape adds sophistication. At the heart of this timepiece lies the Zenith caliber El Primero 9004, a self-winding movement capable of measuring time to the hundredth of a second thanks to its balance wheel operating at an astonishing 360,000 beats per hour. The chronograph feature shines with its own escapement system and 50-minute power reserve indicator. With a water resistance of up to 100 meters, this watch is as durable as it is stylish. Its versatility makes it perfect for both casual and formal occasions, and the high-quality strap complements its design beautifully.
