Every detail of the dial contributes to the strong identity of this iconic timepiece.
At the heart of the watch beats the famous El Primero caliber, an automatic chronograph movement oscillating at 36,000 vibrations per hour. This high frequency enables exceptionally precise timekeeping and is one of the most admired technical hallmarks of Swiss watchmaking.
The watch is in excellent condition and has been recently serviced, ensuring optimal performance. It is mounted on a leather Bracelet with its original Zenith folding clasp—an elegant combination that enhances the model’s dressy character while retaining its sporty spirit.
This piece is offered as a 2007 Full Set, complete with its original box and outer case—items particularly prized by enthusiasts and collectors.
Technical, prestigious, and timeless, this Zenith El Primero Grande Class is a watch with character, designed for enthusiasts of exceptional mechanical chronographs.
