About this watch

The Zenith El Primero Chronomaster Power Reserve Black Bracelet is a masterpiece of horological excellence, combining exquisite craftsmanship with cutting-edge technology. Its striking design features a black dial with silver indexes and hands, set in a 42mm round stainless-steel case. The dial's stick and dot indexes ensure optimal legibility, while the chronograph sub-dials add a layer of complexity without cluttering the face.

This high-frequency movement operates at 36,000 vibrations per hour, ensuring incredible accuracy and reliability. The 50-hour power reserve ensures that even when not worn, it keeps perfect time. With its column wheel mechanism and solid pushers, the chronograph functionality is both refined and smooth. The watch's ergonomic design makes it surprisingly comfortable to wear, with a stainless-steel bracelet that fits snugly without pinching. Its water resistance of 100 meters makes it suitable for active lifestyles, while its versatility allows it to seamlessly transition from formal to casual events. This timepiece is not just a statement piece but also a celebration of horological excellence.
