The El Primero 03.2170.4613/02.M2170, seen from the bench

The Zenith El Primero 03.2170.4613/02.M2170 represents a modern interpretation from 2000–2010 of the legendary 1969 chronograph that revolutionized watchmaking with the first automatic high-frequency movement at 36,000 vph. This model features a 40mm stainless steel case with the Zenith caliber El Primero 4613 movement, displaying hours, minutes, and small seconds without chronograph pushers, emphasizing minimalist elegance. The 20mm lug width is a classic Swiss proportion suited for everyday wear with refined sportiness.
