The Zenith Defy El Primero 21 49.9000.9004/78.M9000 is a remarkable timepiece that combines style and functionality. Its standout feature is the skeleton-style dial, which perfectly complements the all-black design while ensuring readability is not compromised. This watch is designed for those who appreciate both form and function.

Clear and Elegant Markers

The hour and minute markers on this watch are prominently displayed on an outer chapter ring around the dial. At 12 o’clock, you’ll find a linear crescent-shaped power reserve indicator, positioned just above the Zenith and El Primero 21 logos. This arrangement adds a touch of elegance to the watch face.

Enhanced Legibility in Low Light

In low-light conditions, such as darkness or dimly lit rooms, the Zenith Defy El Primero 21 49.9000.9004/78.M9000 ensures that you can still easily read the time. The hands and indices are coated with Super LumiNOVA phosphor, matching the watch’s overall black theme. This luminous material provides ample legibility, making it practical for various environments.

Innovative Movement

At the heart of this timepiece beats the Caliber El Primero 9004, a self-winding movement that brings the El Primero Collection into the 21st century. With a high beat rate of 36,000 vibrations per hour (vph), this movement is precise and reliable. What sets it apart is the addition of a chronograph module that operates at an astonishing 360,000 vph, a system known as the 5Hz + 50Hz. This innovative double-chain design enhances the watch’s accuracy.

Precision Chronograph Function

The movement boasts two distinct systems, each with its own balance wheel, gear train, and mainspring. Most notably, it can display 1/100th measuring chronograph readings on an analog layout, highlighting its precision and capability.
