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! You don’t need to make any sacrifices with this watch. A wide variety of complications and clever design features cater to even the most particular of customers. A rectangular-cased chronograph, this Port Royal has a great deal to offer. Within its titanium case is housed three central hands, as well as a power reserve indicator, 30-minute chronograph, and two dial windows. These windows in the dial allow you a rare look at the watch’s inner workings and balance wheel. This transparency is further expounded upon with a clear case back.
