"The Zenith El Primero is one of the most famous and respected automatic chronograph movements in the watchmaking industry. Created by the Swiss brand Zenith, it is often considered one of the most accurate automatic chronograph movements in the world. What sets the Zenith El Primero apart is its high frequency of 36,000 vibrations per hour (10 per second), compared to conventional chronograph movements that operate at 28,800 vibrations per hour. This high frequency allows for more precise timekeeping."
