Zenith El Primero Grande Class Chronograph - 2013

Description:

The Zenith Grande Class El Primero (reference 03.0520.4002) is a striking expression of Zenith's legendary chronograph heritage, built around the celebrated El Primero movement that redefined high-frequency automatic chronographs. Crafted from stainless steel, its case offers a bold, substantial wrist presence with a polished finish.

With its fixed smooth bezel, scratch-resistant sapphire crystal, and exhibition sapphire crystal case-back, this Grande Class El Primero bridges Zenith's racing pedigree with modern refinement. Originally engineered around the world's first automatic chronograph movement, this watch remains a versatile classic—equally at home on the wrist for daily wear or as a showcase piece for collectors.
