About this watch

The Zenith El Primero Chronomaster 42 Aluminium is a stunning representation of Zenith's commitment to excellence, combining modern materials and classic design for a bold yet sophisticated look. At the heart of this watch is the remarkable Zenith Caliber El Primero 400B, famous for its high frequency of 36,000 vibrations per hour, translating to precision that few other watches can match. With a power reserve of 50 hours, you can rely on this watch to keep ticking even after a weekend away. The chronograph feature is a standout aspect, with its column wheel mechanism allowing you to start, stop, and reset the timer with a satisfying click. The analog display offers clarity and elegance in a world dominated by digital screens, while the comfort of the rubber strap and water resistance of 100 m make it a practical choice for daily wear.
