About this watch

The Zenith Defy El Primero 21 Black Ceramic / Skeleton / Alligator is a stunning timepiece that showcases exceptional craftsmanship and innovative technology. Its skeleton design allows you to see the intricate workings of the movement, making it a fantastic conversation starter. The black ceramic case adds a modern touch, while the open-back design gives a sneak peek at the beautifully crafted movement. With its dual escapement system, this watch maintains a high level of accuracy, ensuring consistent performance whether using the chronograph or just checking the time. The watch comes with a power reserve indicator for the chronograph and an alligator leather strap that adds a touch of elegance. Whether you’re dressing up for a formal occasion or going casual, this strap has you covered. With its striking contrast between the skeleton design and bold black ceramic case, this watch is easy to read in any lighting condition. At 44 mm in diameter and 14.5 mm in height, the Defy El Primero 21 has a substantial presence on the wrist, but it’s surprisingly comfortable to wear thanks to its ergonomic design.
