Zenith - El Primero - Grande Class Open - Column Wheel Chronograph - Ref. No: 03.0520.4021 - Miehet - 2000-2010

Welcome to my Top Swiss Chronographs Boutique!

Zenith SA was started in 1865 by Georges Favre-Jacot at the age of 22, in Le Locle (canton of Neuchâtel), Switzerland.
In January 1969, Zenith announced imminent launch of first fully integrated, high-frequency, automatic chronograph movement "El Primero".
Today, Zenith wristwatches meet or exceed rigorous timekeeping C.O.S.C. standards, a reflection Zenith's history of innovative precision timekeeping.
Stylish and sophisticated, the offered iconic timepiece combines the traditional precision of the famed mechanical chronograph and a modern look of first-class materials. It is a gentlemen’s dress chronograph wristwatch that internally utilises one of the most highly regarded movements ever produced. Just look at this movement (through the transparent case-back): this is a true ode to watchmaking!

General professional pre-sale service was made in October 2024: the watch is keeping good time and working perfectly.
Distinctive design.
High recognition level.
One of world's best movements: you just take a look at this marvelous piece of watch-art!
Excellent condition, never worn: the wristwatch comes from luxury watch-shop showcase; that's why the strap is replaced with brand new one (leather straps often suffer from temperature in shop windows due to powerful spotlights).
My personal authenticity and quality warranty: you will get warranty card (as pictured), fully completed and signed on the back.
Insured, registered shipping worldwide.

Everything you see in my pics is included in the package that you'll receive.

NO EXTRA COSTS for EU Buyers!

Personal note: Christmas is approaching, and with it the postal congestion. As a result, very long and less successful parcel deliveries in December. My advice: hurry up to buy and - most importantly - receive your watch on time.
