About this watch

The Zenith Defy El Primero 21 is a stunning fusion of art and engineering, boasting a full carbon body that's not only futuristic but also incredibly lightweight. The skeleton design reveals the intricate inner workings of the watch, making it a feast for the eyes. At its heart lies the El Primero Caliber 9004, a self-winding movement that's a marvel of precision engineering. With a cam-actuated chronograph capable of measuring time down to 1/100 of a second and a water resistance rating of 100 meters, this watch is perfect for those who lead an active lifestyle. The lightweight carbon material makes it feel smaller on the wrist, while the rubber strap adds another layer of comfort. It's a statement piece that's not just about telling time but embracing a lifestyle that celebrates craftsmanship and innovation.
