About this watch

The Zenith Defy El Primero 21 Black Ceramic / Skeleton / Alligator is a marvel of modern watchmaking, showcasing Zenith's commitment to pushing the boundaries with its striking black ceramic case and skeleton dial. This timepiece is a statement, a blend of functionality and artistry. The bold design features an alligator leather strap that adds a touch of elegance, while the 44.00 mm diameter and 14.50 mm height make it substantial without being overwhelming. At the core of this masterpiece is the Zenith caliber El Primero 9004 movement, a self-winding marvel capable of measuring time to a precision of 1/100 of a second. The chronograph runs on its own escapement system, with a balance wheel operating at an astounding 360,000 beats per hour. This innovative movement features dual balance springs made from a carbon-matrix carbon nanotube composite, enhancing precision and reliability.
