Welcome to my Top Swiss Chronograph Wristwatches 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!
