Zenith SA was started by Georges Favre-Jacot and is one of the oldest continuously operating watchmakers. Favre-Jacob invented the concept of "in-house movements", believing that only through control of the entire watchmaking process could perfection be achieved. At the 1900 Paris Universal Exhibition, Zenith won its first award for chronometry and in honour of that award, the manufacturer released the Grand Prix Paris 1900 pocket watch, which featured a depiction of the prize on the case. Currently, Zenith has the following collections: Defy, Chronomaster, Elite, and Pilot.
